A router is a kind of network “computer” designed to transfer data between devices that have different interfaces and protocols.

If the PC is unable to access the Internet or access the router settings page, you need to perform a number of operations with the router and PC.

Most often, a communication problem with the router is determined by the messages “ Network cable Not Connected" or "Without Internet Access" as a crossed out image or exclamation mark in the notification area of ​​the taskbar.

Step 1. The first thing you need to do in this case is to check whether the connectors of the network (LAN, Ethernet) cables are correctly connected to the ports (connectors) of the router.

The router port labeled “INTERNET” or “WAN” is used to connect the cable coming from the Internet provider. This port is usually marked with a different color on the router and is sometimes located some distance away from other ports.

The PC and the router, in turn, are connected by an Ethernet cable, one end of which is connected to the RJ-45 connector on the PC, and the other to one of the LAN ports of the router.

Step 2. Reboot the router, because it is characterized by "". To do this, press the “On/Off” or “Power” button on the device. The router lights should turn off. After 15 seconds, press the router's power button to turn it on.

Reference! If there is no power button on the router, disconnect it from the 220V network for a short time and turn it on again after 30 seconds.

Step 3. Test Internet access. If communication with the router does not appear, this may be due to a failure in the network settings. To eliminate them, you need to run connection diagnostics.

1. Press the combination “Win ​​+ R” on the keyboard (“Win” is located to the left of “Alt”).

   

2. In the window that opens, type “control” and click “OK”.

   

3. The “Control Panel” will launch. If sorted, click on “View network status...”. If icons are displayed, select "Network and Sharing Center...".

   

   

4. Click “Change adapter settings” on the left.

   

5. Right-click on the network icon, and left-click on “Diagnostics” (“Fix”).

   

Windows will analyze the network status and identify problems, reporting troubleshooting or identified problems.

Step 4. Reconnect to the network. If the result is negative, replace, if damaged, the LAN cables connecting the PC and the router. Cables can be damaged by being kinked or caught by furniture.

Step 5. Reconnect. If there is no connection, there is probably a problem with the PC's network card. It is recommended to reinstall its driver or replace it in case of malfunction. This is especially true if the Wi-Fi connection is working.

Windows will find and update the board driver.

Step 6. If there is no connection, connect the provider cable directly to the PC connector and configure the Internet according to the recommendations specified in the agreement with the provider. This will ensure that the Ethernet port on the PC is working properly.

Note! It is also possible that the access problem is occurring on the ISP side.

If the Internet appears, it means that the fault is localized in the router and it needs to be reset to default settings.

Resetting the router to factory settings

Let's consider such a reset using the Linksys WRT160NL router as an example. Please note that the name, password and IP address of the router are unique for this device.

Reference! To find out the name, password and IP address of the router, you need to refer to its documentation (including its label) or find out this data via the Internet.

Step 1. Disconnect the computer and router from the 220V network.

Step 2. Disconnect all wires from the router.

Step 3. Turn it on and wait 1-2 minutes until it loads completely.

Step 4. Press and hold the reset button with a thin object (e.g. a paper clip) for about 5 seconds. The router reset button is located at the bottom right of the product label (marked in red). Release the button and wait for the router to reboot and start for 2-3 minutes.

Step 5. Turn off the router.

Step 6. Connect one PC to the router. To do this, insert one end of the LAN cable into the connector on the PC, and the other into port 1 of the router. Turn on the router and wait until it boots up for 1-2 minutes.

Step 7 Turn on PC. Turn off Wi-Fi if it is turned on on your computer. Usually, to turn Wi-Fi on or off, you need to press one of the “F1”–“F12” buttons, which has an “antenna” icon, sometimes together with the “Fn” button, or slide a special switch.

After resetting the router to factory settings, to check its connection with the PC, you need to run the “ping” command.

Step 8 Press “Win ​​+ R” on the keyboard and type “cmd” in the menu that opens, clicking “OK”.

Step 9 Enter “ping 192.168.1.1” in the window that opens and press the “Enter” key. There will be 3 or 4 lines starting with either “Reply from” or “Request timed out”. If the line says “Response from,” then the computer sees the router.

Reference! If you receive the message “Request timeout exceeded”, and the network card and the LAN cable connecting the PC to the router are working, this means that the router is faulty and requires repair.

Step 10 Open your browser and type the router IP 192.168.1.1, press the “Enter” button.

Step 11 In the login menu, leave “Username” blank, and enter admin in the “Password” field. Click "Login".

The settings interface will open.

Step 12 Try setting up the router using the installation CD or manually according to the provider's instructions and see if it can work normally.

Step 13 When the router is operating normally, exit the browser. The router is OK.

Reference! If you receive a “Response From” but the login menu and router setup page do not open, this means either the router is faulty or its firmware is faulty.

In this case, you need to use the Linksys tftp.exe program to start the router by updating its latest firmware.

Important! After updating the firmware, repeat the steps described above, starting with “ Step 1".

Updating the router firmware

Step 2. Click on the found equipment on the left.

Step 3. Click “Downloads\Firmware”.

Step 5. Click “Agree”. The download of the firmware file will begin.

Step 7 After the page loads, click on the word with the download link “here” (“here”) in the line “i. TFTP Utility - To download the TFTP utility, click here."

Note! The downloaded file can be opened in the “Settings” - “Downloads” parameters.

Step 8 Run the installation file Tftp.exe by left-clicking on the “Open” option.

Step 9 Enter 192.168.1.1 in the “Server” line and admin in the “Password” line.

Step 10 Click the select button (with three dots) in the “File” line, click on the downloaded firmware file in the menu, then “Open”.

Step 11 Click “Update”.

A firmware update indicator will appear and, upon completion, a message indicating that it was completed successfully.

Step 12 Enter 192.168.1.1 in the browser search and click “Enter”. The login menu will appear. Leave the “Username” blank, and enter admin in the “Password” field. Click "Login".

The router settings page should open and access to it should be restored.

The process of setting up a wired network router

Internet providers use several protocols for user connection:

• (issued) IP address (DHCP);
• fixed user IP;
• PPTP (point-to-point connection);
• L2TP (layer 2 tunnel);
• PPPoE (link layer).

Before connecting, you need to find out what protocol the provider uses, as well as (if available) the user name and password. Typically this information is provided in the contract concluded with the provider.

If DHCP is used, which happens in most cases, then the Internet should work immediately after connecting the router to the cable from the provider, because Routers are configured for DHCP by default. If another protocol is used, you need to register it in the router.

Let's look at using the PPPoE protocol using the TP-LINK router as an example.

Step 1. Connect the router to the PC and the provider's cable. Turn on both devices.

Step 2. Right-click on the connection icon, selecting “Network and Sharing Center...”.

Step 3. Click on the "Ethernet" option.

Step 4. Right-click on the “Connection…” shortcut, left-click on the “Properties” line.

Right-click on the “Connection...” icon, left-click on the “Properties” line

Step 5. Left-click on the line “TCP/IPv4” (in Win XP – “TCP/IP”). Click Properties.

Step 6. Left-click the lines “Obtain an IP address automatically”, “Obtain a DNS server address automatically”. Click OK.

Step 7 Launch your browser, enter 192.168.0.1, press Enter. In “Name...” and “Password” type admin. Click "Login".

Enter 192.168.0.1 into the search field of the browser, press “Enter”, in the login window type admin in both lines, click “Login”

Step 8 Select “Network” – “WAN” on the left.

Step 9 On the right in the drop-down list, select the type “PPPoE/Russia PPPoE” in the “WAN Connection Type” line. Enter (check) the remaining data shown in the photo below. Click "Save".

Step 10 Click on the “Status” section on the left and write down the Mac address of the router, which, if necessary, must be reported to the provider.

Wi-Fi setup process

Step 1. Click on the “Wireless” – “Wireless Settings” section on the left.

Step 2. In the “Wireless Name” line, specify the name of the network that will be displayed by the router for connecting to Wi-Fi. Enter (check) the remaining data indicated in the photo below. Click “Save”.

Step 3. Click on the “Wireless Security” subsection on the left.

Step 4. Scroll down the page and enter (check) the information indicated in the photo. Enter the Wi-Fi connection password in the “PSK Password” line. Click “Save”.

The router's connection to the Internet is complete.

Is your computer terribly slow?

Many people are familiar with the annoying situation when the operating system slows down and slows down, sometimes so much that it loses important data due to the impossibility of saving it. There are ways to get rid of these problems, but it is better not to fall into them.

Helpful steps in this case:

1. Scan your computer for viruses. If your PC is constantly slowing down, it most likely contains malware, adware, or a virus. A scan will identify the problem and usually fix it.

   

2. Get rid of unused programs. It is better to remove unnecessary software along with entries that can slow down your computer.

   

3. Clear the registry. This can have a big effect, and it is better to do the cleaning using specialized software, because... Manual cleaning requires special knowledge.

   

4. Defragment HDD. This will allow you to collect files “scattered” on the disk, which will speed up the OS access to them.

   

5. Don't multitask too much. The user can be productive when working with only a few programs, and the likelihood of the PC slowing down will be significantly reduced.

   

6. Update equipment. Computers on average are designed to last up to 5 years, as technology develops very quickly.

   

7. Reinstall the operating system. This is an extreme measure, but sometimes the only one that brings back the “fast old” PC.

   

As you can see, all that usually needs to be done if the computer “slows down and freezes” is to give it a little attention from time to time, which only takes a few minutes.

Video - Why the Internet does not work on the computer

09.11.2017

The computer does not see the router. Why is Wi-Fi not visible?

Many users sooner or later encounter this problem. There may be various reasons why Wi-Fi on a laptop does not work. Perhaps you recently installed a new operating system, bought a new router or flashed an old one, etc.

In general, if you also find yourself in such a situation, and you I can’t connect my laptop to the Wi-Fi network, then in this article we will look at several methods that should help you connect your laptop to Wi-Fi.

Let's start with the simplest - reboot the router. To do this, you need to unplug the power supply, wait 10 seconds and plug it back in. Then restart your operating system.

Do network diagnostics. Although many will be quite skeptical about this advice, sometimes it can also help. Right-click on the wireless network icon in the tray and select "Diagnosing problems". Windows will scan and if it finds a problem, it will suggest ways to solve it.

If after this, the laptop still does not see Wi-Fi, check Is wireless enabled on the laptop? wifi adapter .

Find the wireless network icon on one of the F1-F12 buttons, for me it’s F2. Also, on the button itself, near the power button or touchpad, there should be a light indicator that indicates that Wi-Fi is on. Specifically in my case, if Wi-Fi is turned off, the indicator light is on. To turn it on, press the combination Fn+F2.

You also need to check that the network card is enabled. To do this, right-click on the wireless network icon in the tray and select "Network and Sharing Center".

In the next window click "Change adapter settings".

If you have "Wireless network connection" highlighted in grey, right-click on it and select “Enable”.

After this, the icon should become colored. This indicates that the network adapter is enabled and the laptop can connect to the Wi-Fi network.

Check your network adapter drivers. Click “Start” and write in the search bar "Device Manager" and follow the found link.

There are several main reasons why computer can be isolated from the rest of the network. Usually the problem lies in incorrect firewall settings and similar programs.

Instructions

Open the Start menu and go to Run. Enter the cmd command in the field that opens and press Enter. Type the command ipconfig /all in the menu that appears and write down the MAC address of the desired network card. Enter its value in the above table.

Clear the Routing Table or Route Table menu items that are associated with this computer ohm Make sure that NAT is enabled for this PC. Save your router settings.

Now check the settings yourself computer A. First, be sure to disable third-party programs that control network traffic. This could be the Outpost Firewall utility or its analogues. Now turn off the Windows Firewall service. As practice shows, it is very difficult to configure it yourself, and the effect of its work is too little.

Open the Start menu and go to Control Panel. Find and open the “Administration” item, which is located in the “System and Security” menu. Open Services. Find the service " Windows Firewall", right-click on it and select "Stop". Now open its properties and set the “Startup type” field to “Disabled”.

Check the network adapter settings. Make sure that the specified IP address is within a valid zone. Try changing its value to the address of one of the network computer ov, after turning off the second PC. Reboot computer and try again to access network resources.

The list of reasons why a computer/laptop freezes is quite long: failure of operating system system files, overload of system resources, bad sector on the hard drive, overheating of internal parts, exposure to viruses, and others. If your laptop freezes, you need to restart it.

You will need

• - administrator rights.

Instructions

Laptops, unlike desktop computers, do not have a Reset button on the case. Therefore, when the system freezes, the user has only one option: turn off the device completely. To do this, you need to press the power button and hold it down until the laptop turns off (usually no more than 30 seconds). As a rule, the button is kept pressed all this time. Users often do not wait for the shutdown time and think that their laptop is not turning off.

If the shutdown occurred due to severe overheating (this can be felt by abnormally hot air near the ventilation holes of the laptop on its own. Such actions will void the warranty on the device if the warranty period has not yet expired. Contact specialists at the service center, and they will definitely help you solve this problem , however will have to pay.

What to do if WiFi does not work on your laptop: Video

An article about the reasons for this. that the computer or laptop does not see the Internet entry point through the router. Ways to fix the problem.

Navigation

There are times when when connecting a computer or laptop via router, to the Internet access point, the entrance remains unavailable. In this case, you should find out the reasons why router does not see the entrance to the World Wide Web.

Lack of internet can lead to big problems at work

The reasons may be different. For example, the router is working, but there is no Internet access point on the computer device.
Reasons for the above situation:

• working programs are not installed.
• error of technical equipment (hardware).
• lack of Internet connection.
• WiFi module failure and many other problems.

We will look at the most common Internet access problems and their elimination. Let us give an example of solving problems for router companies Tp-Link.

Solutions to the problem when the driver program is not installed

• We are waiting for the computer device to correct the breakdown itself.
• We accept a message about fixing problems or a hint about further actions.

Solving the problem of hardware error

A hardware error or error is a problem with the components for assembling a computer device (video card, processor device, etc.).

Errors occur when there is a heavy load on the device, operation at elevated air temperatures, incorrect settings, failure of the radiator fan, and so on. As a result, the computer simply breaks down, it follows that WiFi hotspot absent.

The solution of the problem:

• If the computer does not work due to system overheating, the broken part should be replaced. Repairs can be made at a service center.
• If a computer or laptop does not work due to a disconnected antenna, check whether the antenna is connected to the adapter and whether the connection terminals are clogged with dust or dirt.
• If the above actions do not lead to the desired result, the devices do not see the Network access point, contact a technical support center and a specialist.

After reviewing general access point questions WiFi, we'll tell you why it may not work wireless network on routers companies Tp-Link.
Example, Tp-Link router connected, in working mode, the Internet does not pass through.
The problem is solved in the following way:

• check switching on WiFi on a computer device
  check if you see other networks.
• when purchasing a new router, the network will have a standard name. Turn off the router, noting which network will disappear.
• reboot your router.
• access to Net will recover.
• if the problem persists, check the router's connection to the electrical network and turn on the key ON/OFF on the device (option No. 1).

Check the router's connection to the network electric current and turn on the ON/OFF key on the device

• check that the wireless network is turned on router, a key built into the body (see figure, option No. 2).

Check that the wireless network is turned on on the router using the key built into the case

• access to Net will recover.

In the event that the above actions do not lead to positive result, you will need to check the settings.
Scheme:

• go to settings router.
• enter the login address in the browser line 192.168.1.1 (0.1).

Go to the specified login address 192.168.1.1 (0.1)

• specify the username and password (standard username - admin or a new name).
• on the settings panel, enter the mode Wireless ("Wireless mode").
• set icons on lines “Enable wireless broadcasting of the router” (Wireless Router Radio) And "Enable SSID Broadcast."

Set the icons on the lines “Enable Wireless Router Radio” and “Enable SSID Broadcasting”

• reboot your device.
• activate the key "Save".
• signal transmission WiFi network using Tp-Link router, will be in action.

We have looked at the main problems and their solutions that make it impossible to access Net through router on a computer, laptop.

We hope you find the information useful! Good luck on the Internet!

We have already looked at solutions to many problems that may arise when connecting a laptop to a Wi-Fi network, or during use. But, there is one popular problem that I have not written about yet. This is when the laptop does not see the Wi-Fi network. In principle, the problem applies not only to laptops, but also to desktop computers that are connected to Wi-Fi via an adapter (external or internal). The problem when the laptop does not see Wi-Fi can be encountered in Windows XP, Windows 7, Windows 8, and even in Windows 10. If you have Windows 10 installed and the computer does not see your router, then see separate instructions:. Since the solutions there are practically the same, it doesn’t matter what system your laptop is running on. Now we will try to figure out why the laptop does not see wireless networks, using Windows 7 as an example.

Before moving on to any settings, let's try to figure out what problem you specifically have. There are two options:

• When no Wi-Fi network is displayed in the list of networks available for connection. That is, the computer does not find Wi-Fi at all. But, are you sure that there are wireless networks within the radius? Other devices see them.
• And when the laptop does not see only your Wi-Fi network, but sees other neighboring networks.

I will divide this article into these two parts. You can immediately go to the required section with the solution to your problem.

Another important point. If you have an error on your computer "No available connections" , and a red cross next to the Wi-Fi connection icon, then there is a separate solution to solve this error.

Why doesn't my laptop see wireless networks (not a single one)?

The most popular reasons:

• There are no available networks within the radius (we have already ruled this out)
• The wireless adapter driver is not installed and therefore cannot find wireless networks. Or the driver is installed, but does not work correctly.
• Wi-Fi on the laptop is simply turned off.
• It happens that the Wi-Fi receiver is simply faulty or disabled (for example, while cleaning a laptop from dust).

But, most often, of course, the problem is a disabled wireless adapter, or the absence of the necessary driver. This is what we will consider now.

Checking the wireless adapter driver

If you see a connection icon in the form of a computer with a red cross on your notification panel, then the driver is most likely not installed.

To check, we need to go to the device manager. Open menu Start, right click on Computer, and select Control. In the new window, go to the tab device Manager. Open section Network adapters , and see if there is an adapter whose name contains the words “Wi-Fi” or “Wireless”. It looks something like this:

If such an adapter is not there, as a rule, in this case only one adapter (network card) is displayed there, then it needs to be installed. If it is there, then it should be without any icons, like in my screenshot above. If there is an icon near the Wi-Fi adapter, then right-click on it and select Engage. Most likely you will have to install the required driver. We have separate installation instructions: .

If everything is fine with the driver, then let's Let's check if Wi-Fi is turned on on your computer.

Right-click on the network connection icon, and select Network and Sharing Center. Then, select Change adapter settings.

After this, the computer should see wireless networks, and you can easily connect to your Wi-Fi network.

You may have wireless networks turned off by a keyboard shortcut on your laptop. You need to check, I wrote about this in more detail in the article:. And if you have a “ten”: .

After these steps, everything should work for you. The main thing is that the Wi-Fi network icon with a yellow asterisk appears, this means that there are networks available for connection.

The laptop does not see my Wi-Fi, but does see others. Solution to the problem.

If above we considered the situation when wireless networks are not displayed on the laptop at all, now we will figure out why the laptop does not see only one Wi-Fi network that we need. And other networks, neighboring ones, are displayed in the list of available ones. This problem most often appears on mobile devices: smartphones and tablets. But computers are no exception.

In this case, the problem must be looked for on the side of the Wi-Fi router. Almost always, the solution is the same: change Wi-Fi network channel. If the router itself, or you are in manual mode If you set the settings to static channel 13, then the computer most likely will not see the network. Therefore, you need to check and change the channel in the router settings. I wrote in the article how to change the channel on different routers:

For example, change the channel on Tp-Link. You can change it in the settings, on the Wireless tab (Wireless mode). Try to put static channel (just don't put 12 and 13), or set to Auto.

If it doesn’t help, you can also change the name of the Wi-Fi network. You can also do this in the settings, on the wireless network settings tab.

While developing wireless networks, developers came up with the wifi standard. This is when one or more computers connect to a wireless access point and access the Internet through it. Or through a router. Before finding out the reasons why the laptop does not see wifi, we think it would be logical to learn something about this technology.

How should the term be understood correctly?

When we ask ourselves why the laptop does not see wifi, we mean that there is no Internet network. In truth, this is not entirely true. It’s just that wifi is and if a device is equipped with it, then it is certified to work in these networks, that is, it is a guarantor of normal functioning for the intended purposes. Just as there are copiers from Xerox, and there are copiers from other suppliers. However, out of habit, people call any paper multiplier a “copier”.

WiFi equipment

Among most devices for wireless access, two categories of equipment can be distinguished: “access point” and There is also an extended access point - a multifunctional wifi device.

The hardware of the equipment is similar, it differs in the firmware and, as a result, in the quality of work. If you have problems with the network and you think that the laptop does not see the wi-fi router, then the problem is not always in the machine itself. The router firmware may be flawed, which causes unstable communication with the access point.

Optimal choice equipment with high-quality software should include:

• Reputation of the manufacturer (branded models are less likely to glitch).
• Careful study of even top-class models. It is recommended to have a review with a specialist.

How to connect to wifi. Connection setup

One way is to use the services of cable network providers, and then install wifi equipment on the wired connection.

The next option is to connect through the appropriate access point on the provider’s local network, if such a service is provided by them.

The access point is a hardware radio wave amplifier with the function of receiving and transmitting content. A radio signal is received from the PC wifi standard, which she accepts. The signal is unified for equipment from different manufacturers, which allows you to avoid developing thoughts like “the laptop doesn’t see wifi, it’s probably because my equipment is incompatible with the access center.”

Connecting wifi in windows xp via laptop

Step-by-step setup is discussed below.

1. Enable with a hardware button or key combination (depending on the model). In this case, as a rule, the indicator light should light up - a light bulb indicating that the receiver is turned on.
2. For some laptop models, enabling the wi-fi module is provided by special instructions regulating the procedure. If necessary, check whether this is the case in the relevant documentation.
3. If your receiver uses Wimax technology, you can configure this operating mode using special software.
4. Enable the wireless access service (right click on the My Computer icon - management - services and applications - services - wireless setup - start, if the service is not running).

If the laptop does not see wifi router, and the system reports this, which means that most likely a special driver utility from the wifi equipment manufacturer is responsible for managing the wireless connection. Open “Network Neighborhood” - “view available wireless networks”.

If the router does not respond at all, then the problem is purely technical. In this situation, you should look for a problem in the wires, power supply, or take the router for repair. As a rule, it is easier to replace the router with a new one than to send it to service centers for inspection.

Drivers

As you know, any equipment requires software that guarantees stable operation. If the laptop does not detect WiFi, then you should check the drivers. Even if they are installed, it is recommended to update them.

You can check drivers through the control panel. In the “device manager” section there is a line “network adapters”, which should contain the name of the router if the problem is with the drivers. Right-click on it and look at the driver version. Compare it with the real version, which can be found on the Internet.

If the version is outdated, then download a new one and install. It is best to download from official sources. Drivers for hardware are distributed by developers free of charge, and there is no point in risking the “health” of your operating system in vain.

Signal distance

If, after searching for a network, the answer appears: “No connections available,” think about the signal. In apartments, this option is not very relevant, since modern routers have a strong signal and distribute it quite far. But in private homes or other places where the distance can be quite large, the signal simply may not reach the laptop. Therefore, you should not be surprised if the Internet suddenly disappeared while you were walking around the house or yard.

Mac address

There are situations when I was able to connect, but the router does not see the Internet through my WiFi or has stopped seeing it. When using services from some providers, the user cannot simply change the network adapter, since the Mac address changes.

The Mac address is written on each router and the user just needs to call the operator to bind a new address to replace the old one. You may be asked to dictate it in full or to specify only the last few values ​​of the entire number.

Antivirus or third party programs

Third-party programs installed on a laptop may conflict with drivers or interfere with the correct establishment of an Internet connection, which often happens when the device sees wifi but does not connect. In addition, sometimes antiviruses interfere with creating a connection. If possible, it is better to try connecting to the Internet without a router first. If everything is fine, then the programs are not to blame.

In addition to those listed, there can be many reasons. Basically, the variety of reasons is due to problems with the operating system. Therefore, if all else fails, try reinstalling your operating system. Perhaps all the problems come from here.

The laptop does not see the WIFI network on Windows7/Windows 8/WindowsXP

For those who are wondering why the laptop does not see wifi in Windows 7, first of all, you need to try manually turning on the wireless network.

To do this you need:

In Windows 8, activity is checked through the “PC Settings” item. Next, you need to select the “wireless connection” line and move the slider on the right side of the menu to the “On” state.

The wireless network when using Windows XP does not require manual activation and, as a rule, connects just like Windows 7. It is enough to activate it through the control panel or through the wireless icon via bottom panel systems.

How to set up a wireless network

For comfortable use of the network, some users resort to settings. Usually, standard settings are enough, but if you want, you can delve into your personal account. It is through your personal account that parameters are changed.

The login and password are specified by the router manufacturers, and you can find this data in the instructions. The address that will take you to Personal Area. It is best to replace the default data so that no one can use it.

All other settings are made on the laptop itself, and they are installed using the Network Control Center.

WiFi without internet due to Windows

There are rare cases when the operating system itself does not want to determine wireless connection and shows that there is no external network at all. This option may exist when using non-licensed OS. Some people prefer to use amateur assemblies, which do not load the system as much and allow you to squeeze more out of the hardware.

Another reason could be a clogged system. System folders, over time, become clogged with unnecessary files, and if defragmentation is not carried out, the processor will be increasingly loaded. Antiviruses also cannot keep a laptop clean forever.

In any case, all problems with the OS can be solved by a simple reinstallation. After Windows reinstallation everything should work. Thus, the solution to the problem lies only in the functionality of the router, enabled WiFi on the laptop, or the presence of the necessary software. If these points are observed, WiFi will not present difficulties and will delight the user with stable operation.

A fairly common problem among owners of laptops with Windows 10, Windows 7 or 8 (8.1) - at one point in the notification area, instead of the usual wireless Wi-Fi connection icon, a red cross is displayed, and when you hover over it, a message stating that there are no available connections.

Moreover, in most cases, this happens on a completely working laptop - just yesterday, perhaps, you successfully connected to an access point at home, but today this is the situation. The reasons for this behavior may be different, but in general terms, the operating system believes that the Wi-Fi adapter is turned off, and therefore reports that there are no connections available. And now about ways to fix this.

If Wi-Fi has not been used on this laptop before, or you have reinstalled Windows

No access to Wi-Fi network

If the laptop does not see the wireless network, then the first thing you need to do is check whether the adapter is turned on on the laptop. Take a look at the row of keys F1-F12: on one of the keys there should be a designation of the antenna receiving the signal. Find this key and press it in combination with the Fn button - for example, Fn and F2.

Some laptop models use a hardware switch instead of hot keys, which is located in the front of the case. After pressing a keyboard shortcut or using a hardware switch, a message should appear indicating that Wi+Fi is on/off. Naturally, you need to put it in an active state.

But that's not all: sometimes the wireless connection in the system is turned off, while the adapter itself is working. To resolve this issue:

1. Open Network and Sharing Center.
2. Go to the "Change settings" section.
3. Find your wireless network and make sure it is working.

If the adapter is turned on, the wireless network is active, but you still cannot access the Internet, then it makes sense to check the Wi-Fi drivers. This is especially true if connection problems began after reinstalling Windows.

1. Right-click the Computer icon.
2. Open the Manage tool.
3. Go to Device Manager.
4. Find the wireless connection module among the network adapters.

Even if it says that the equipment works correctly, do not be lazy to go to the official website of the laptop and download drivers for the Wi-Fi module of your particular laptop model.

Checking router settings

If the laptop does not pick up the wireless network, but you see that everything is fine in the system, then you should pay close attention to the router. Make sure the alarm device is working properly. Go to its web interface and look at the Wi-Fi settings.

1. Enter the router's address in the browser (192.168.0.0 or another specified on the router).
2. Open advanced settings and make sure Wi-Fi is turned on.
3. Save the correct configuration and close the router interface.

After applying the new configuration, try connecting to your wireless connection again. For it to appear in the list of available networks, turn off and turn on the Wi-Fi adapter on your laptop.

Local network problems

We've figured out the wireless connection, now let's look at a more complex situation - the device doesn't see local network, although you connected the Internet cable to the network card connector. What to do in this case?

First check if the wire is damaged. Often it is the faulty state of the cable that leads to the fact that the laptop cannot detect the local network. If the wire is broken or cut, it needs to be replaced.

The second step is to check the network card connector into which the Internet cable is inserted. If you removed the wire carelessly or dropped the laptop, the connector could be damaged. The problem is resolved at the service center, where they will replace your broken port. Another unpleasant situation of this kind is a burned out network card. It is also better to entrust the operation of replacing it to specialists: after all, a laptop is not a computer where modules can be changed at home.

But before you go to the service, be sure to check the network card drivers: they may have failed. This can be done through the “Device Manager”, the launch procedure for which we described above. The principle is the same - download drivers for the network card from the official website of the laptop manufacturer and install them, and then check again whether the local network is detected.

A fairly common problem in laptops is when it stops seeing the list of Wi-Fi networks. Moreover, this can happen completely spontaneously. Just yesterday everything was working, and today it says that there are no connections available. In this article, we will look at this situation in detail, and also give some tips on how to make the laptop start seeing Wi-Fi again.

Possible reasons why the laptop does not see WiFi

Now we will give a list of the most common reasons why your laptop might have problems displaying WiFi networks.

1. The Wi-Fi adapter is disabled using a special key combination or a special lever.
2. There are problems with the drivers for the Wi-Fi card.
3. The occurrence of errors and conflicts in operating system.
4. Wi-Fi card malfunction.

We have described the main causes of this problem in order of their prevalence.

Now we will look at each option in more detail, and also give you the correct sequence of actions that need to be taken in case of problems with Wi-Fi on a laptop.

Troubleshooting

The first thing to do in such a situation is to determine what the problem is - with the laptop or. To do this, you need to try connecting to your Wi-Fi, for example from a phone or tablet.

If WiFi is visible and works normally with other devices, then the problem is in the laptop. If there is no Wi-FI on other devices, then you need to check the router settings.

Now that it has become clear that the problem is on the laptop, we will try to solve it.

Checking whether the Wi-Fi adapter is turned on

First, check the condition of the special lever on the sides of your laptop. It is present in laptop models approximately 2000-2010 years old.

It looks something like this:

Wifi switch on laptop

Wifi button on laptop

Wifi button on laptop

If there is one, try switching it to the opposite state by moving it to the side.

If there is no wifi switch on the laptop body, then try turning it on using a key combination on the keyboard. Usually these are buttons FN+F2.

Keyboard shortcut to turn on Wi-Fi

But instead of F2, there can be any other F button in the top row of the keyboard with an image of an antenna. Try pressing it separately, as well as together with the FN button.

If you have an operating system Windows 8.1 or Windows 10, then please note that the “ In airplane" was turned off.

Airplane mode

Trying to change the Wi-Fi driver

To do this, go to the device manager and find in the section “ Network adapters”your wifi card. It can be called differently, but the name must contain the words “ Wireless" or " Wi-Fi“.

Reinstalling the Wi-Fi card driver

Right-click on it and in the menu that opens, select “ Delete“.

After that, click on the update hardware configuration icon in the top line of Device Manager.

“Update hardware configuration” button

This will reinstall the drivers on the Wi-Fi card.

Problems with the operating system

Quite rare, but still possible, are cases where Wi-Fi does not work due to problems in the operating system. This may be the result of an unsuccessful update or malware on the laptop.

In this case, it is worth trying to use System Restore, if, of course, it is enabled and there are restore points.

System Restore

The most effective method in this case is to reinstall Windows.

Problems with WiFi adapter

If none of the above options helped you, then most likely your Wi-Fi adapter has failed and will need to be replaced.

This is what a wi-fi card looks like in a laptop

By the way, now it's very big choice USB Wi-Fi adapters on Aliexpress for a couple of dollars.

A fairly common problem among owners of laptops with Windows 7 or Windows 8 (8.1) - at one point in the notification area, instead of the usual wireless Wi-Fi connection icon, a red cross is displayed, and when you hover over it, a message stating that there is no .

Moreover, in most cases, this happens on a completely working laptop - just yesterday, perhaps, you successfully connected to an access point at home, but today this is the situation. The reasons for this behavior may be different, but in general terms, the operating system believes that the Wi-Fi adapter is turned off, and therefore reports that there are no connections available. And now about ways to fix this.

If your wireless network was working and now there are no connections available

If everything worked recently and now you have a problem, try the methods listed below in order. And if these options have already been tried, go to the seventh point, from which we will begin to describe in detail (because everything is not so simple there for novice computer users).

7. Remove the wireless Wi-Fi adapter from Device Manager, install it again

To launch the manager, press the Win+R keys on your laptop keyboard and enter the command devmgmt.msc, and then press Ok or Enter.

In Device Manager, open the “Network adapters” section, right-click on the Wi-Fi adapter, see if there is an “Enable” item there (if there is, turn it on and do not do everything else that is described here, the message “No connections available” should appear) disappear) and if it is not there, select “Delete”.

After the device is removed from the system, in the device manager menu, select “Action” - “Update hardware configuration”. The wireless adapter will be found again, drivers will be installed on it and, perhaps, everything will work.

8. See if the WLAN Auto Configuration service is enabled in Windows

In order to do this, go to the Windows control panel, select “Administration” - “Services”, find “WLAN Auto Configuration” in the list of services and, if you see “Disabled” in its parameters, double-click on it and in the field Set the “Startup Type” to “Automatic” and click the “Run” button.

Just in case, look through the list and if you find additional services that have Wi-Fi or Wireless in their name, turn them on too. And then, preferably, restart your computer.

We hope one of these methods will help you solve the problem when Windows says there are no Wi-Fi connections available.

The misunderstanding, which we will touch on in our article, increasingly worries users of laptops connected to a wireless network. This misunderstanding is of a technical nature - the essence of the problem is the unexpected refusal of the built-in or external router to receive and transmit data.

In this case, the network icon in the tray takes on a characteristic appearance - a ladder crossed out by a red cross - and when you hover over this cross with the mouse, a message appears stating that there are supposedly no available connections in Windows 7. This behavior of the network comes as a complete surprise to the user. We will teach you how to deal with this problem, but in the meantime, draw your attention to the fact that it often appears immediately after reinstalling the operating system. It may very well be that the cause of the network failure is incorrect installation of drivers or installation of drivers that are not entirely suitable for your adapter model.

In this case, find out the model of your adapter and download the latest drivers for it. To do this, go to the laptop manufacturer’s website - they will probably be found there. Download and install everything that is offered to you. The fact is that in addition to the drivers necessary to ensure the operation of the network, drivers may also be required to support function keys.

Many laptops use function keys like “Fn” to control the adapter. If you do not use these keys, then controlling the adapter becomes a hassle. The so-called flight mode is also activated by the keys. Without installing the appropriate programs, you lose most of the functionality. It's no wonder that the WiFi module begins to behave strangely.

First attempts to fix the problem

To get started, we can suggest trying the following:

• Rebooting the router sometimes helps. To reboot, simply unplug the power cord from the outlet and plug it back in.
• Call the standard Windows diagnostic tool from the context menu of the connection icon.
• Sometimes the WiFi hardware switch on the laptop panel is turned off. Check its condition.
• To do this, you can try to run the service utility supplied by some computer manufacturers along with the drivers.
• Go to the "Network connections" section of the control panel. Check if the wireless connection icon is active. If not, activate it from the context menu.
• Check the drivers again.

In theory, these events should liven up your network. However, this may not happen. In this case, follow our further recommendations.

Device Manager - to help

Like any computer device, the wireless adapter is registered in a Windows snap-in called “Device Manager”. You can access the dispatcher in different ways:

• Right-click on the “My Computer” icon. In the context menu, select “Properties”. In the window that opens, select the “Hardware” tab and click on the “Device Manager” button.
• But you can do it differently. Without further ado, call up the “Run” command window and enter devmgmt.msc in the command field – this is the name of the snap-in. The “Run” window itself is called up either with the mouse from the “Start” menu, or with the “Win” + “R” key group.

As a result, a dispatcher window will open, something like the one in the figure:

• Go to the "network adapters" node.
• Expand this node.
• Find in its list a device whose name includes the word “Wireless” - this is the wireless adapter.
• Then right-click on its name and select “Delete”.
• Then go to the main menu of the dispatcher window.
• And in the “Actions” item, click on the “Update hardware configuration” item.

If after this the network remains unavailable, try tinkering with the system services settings.

WLAN Auto Configuration Service

The service in question may also be responsible for the problem. It is located in the same place as all other Windows services, at the address “Control Panel” => “Administration” => “Services”. Find the “WLAN auto-configuration” service in the list and find out whether it is running. To do this, right-click on the service name and select Properties in the context menu that opens. A window similar to the one below will open:

Make sure the Startup Type field is set to Automatic. If this is not the case, then set this parameter, and then restart the service by first clicking on the “Stop” button and then on the “Start” button. Save the changes made by closing the window with the “Ok” button.

If everything is done correctly, the wireless network should become active. If this is not the case, then it is worth looking for other reasons for its inoperability - it may be the equipment itself.

Technology, especially computer technology, can sometimes behave extremely capriciously and present various surprises. Just yesterday you could use your laptop without any problems, access the Internet using a home wireless connection, receive and send hundreds of files and photos, and use social networks. And today there is no connection to the Internet, and in a place where yesterday there was not a single error in the system tray, a mysterious message is shining: “There are no available connections.” And what to do in such a situation is not entirely clear. We will try to analyze the causes of this problem in as much detail as possible and talk about the most effective ways to solve it.

First, we address those who encountered a similar problem after purchasing a brand new laptop or just reinstalled Windows. If in one of these situations you see the message: “No connections available” on your laptop, then most likely there is a problem with network driver, which could easily be missing from the system after reinstalling Windows. Another reason in laptops of various models may be a mechanically disabled Wi-Fi adapter. You can learn how to understand which of the two situations was the primary source of the problem in your case from the instructions below.

If a laptop running Windows reported problems with the connection very unexpectedly, and yesterday everything was in perfect order, there may be several more problems, and we will tell you about each of them today.

Any device can experience difficulties in operation and even freeze, similar to how Windows sometimes freezes. Since the router that distributes the Wi-Fi signal is, in fact, the same computer with an operating system and processor, it can also stop working or freeze. At the same time, a working indication on its body can mislead the user and create the appearance of normal operation of the device, but no signal comes from it at this moment.

The display on the device does not always indicate network problems

In order to return the router to normal operating condition, you need to unplug it, wait a few seconds (7-10) and turn it back on. After giving the device a minute to turn on and start all systems, try checking again for available networks on your laptop.

If you receive a Wi-Fi signal directly from your provider, contact support and describe the situation, mentioning that you have no available connections. The operator will be able to remotely reboot his equipment.

The problem is with the network adapter being turned off.

Please note that many modern laptop models running Windows provide a mechanical way to enable and disable the Wi-Fi connection function. This allows you to save battery power. Find the toggle switch at the ends of your laptop case that is responsible for turning on the wireless adapter, and turn it on. If such a toggle switch is not provided, then it may help you special key at the top of the keyboard with a picture of a wireless signal. In the case where such a button is not on the keyboard, then the manufacturer has probably provided a certain key combination. Most often this is the Fn function key and the F2 or F3 buttons. You can find out more about this information in the manual for your specific model.

After mechanically turning on the wireless network adapter, try searching for available connections again.

The problem is a software-disabled network adapter

Also, the Wi-Fi adapter in your laptop can be deactivated in Windows itself programmatically. To enable it and repeat attempts to find available networks, you need to launch the Panel Windows management, go to Network and Sharing Center, and then in the column located on the left side of the open window, click on the link “Change adapter settings”.

You will see information about all the network adapters and connections contained in your laptop. Find "Wireless Connection" and enable it using the right-click menu.

After that, also try to find available Wi-Fi networks using the system tray icon. The problem you are facing may have been resolved and then you will see an available network. But it may well happen that the adapter refuses to turn on, the items in the context menu after right-clicking the mouse turn out to be inactive, or the adapter turns on but still does not see available Wi-Fi networks. In this case, proceed to the next points of our instructions.

The problem is the driver is not working correctly or is missing.

A specialized program is responsible for each function of the Windows operating system. And a system program called a driver is responsible for the operation of each component in your laptop. It is she who corrects the operation of devices, gives them system commands and monitors the correct execution of these same commands. If your system is missing a driver or has a driver version installed that doesn't quite fit your network adapter, you may also experience difficulty finding, connecting to, and transferring networks.

There may be situations in which the driver was installed, configured, and the system worked quite correctly, but after another simple reboot you saw the message “No connections available” and you cannot access the network. Probably, your operating system has a program that is responsible for automatically updating and installing drivers for various devices, and after a reboot, a driver version was installed that does not match the network adapter model, or a test assembly that does not yet work as desired.

To update and install drivers for various components of your laptop, we always recommend using the two most reliable sources - the website of the manufacturer of the computer itself or the website of the manufacturers of its individual components.

Go to the manufacturer's website, download the latest version of the software for the network adapter, making sure first that it is intended for the same version of Windows that is installed on your laptop. After this, install and restart your PC. To avoid problems when installing a new driver, we recommend that you first remove the existing one by finding your network adapter in Windows Device Manager, right-clicking on its name and going to Properties > Driver > Uninstall.

After installing the latest driver and rebooting your PC, search for available networks again to make sure that all systems are working correctly and that you can connect to the network.

The problem is an incorrect system configuration or a violation of registry settings

When all the previous methods have been tried, but none of them worked desired result, you can resort to a really serious and in-depth search for faults and system problems. This is especially recommended for those users who are confident that before the failure, the network adapter performed its functions correctly and you did not interfere with its operation. In this case, the cause could be third-party programs and applications, their installation or removal, or reconfiguration of individual parts of the system. Any of these actions could not have the best effect on the network operation on your laptop, and then you should resort to the following actions.

If you have a backup of your system using specialized software, try restoring the system to the state it was in when the last checkpoint was created. This procedure will undo all recent changes to the system and return it exactly to the state in which your network adapter performed all its functions correctly. Please note that restoring a copy that is too outdated may deprive you of a large number of settings, programs and parameters that have appeared in the system recently.

If you do not have such a backup, refer to the built-in system Windows recovery, which creates checkpoints during certain key procedures performed on the computer. To do this, open “Your Computer Properties” by right-clicking on the “My Computer” icon on the desktop, and then look for “System Protection” in the column on the left in the window that opens. Click the "Restore" button and select the system state point that needs to be restored on your PC.

If system protection was disabled and checkpoints were not created, we recommend running a full OS scan and checking the integrity of Windows files. There is a special service for this, which can be started using the command line.

Open Command Prompt, manually enter the command sfc /scannow and press Enter on your keyboard. If the system contains damaged files or some parts of the registry are not working correctly, the scanning service will try to detect them and restore them to their original state. This procedure can take quite a long time, and upon completion, a mandatory system reboot will be required.

As a rule, troubleshooting problems with no available connections does not require serious skills and is rarely a reason to contact a service center. You can restore the wireless network adapter using one of the methods given here. If the desired result cannot be achieved using one of the instructions, it may be necessary to combine several methods at the same time. This depends directly on the specific laptop model, its configuration and system parameters.

Quite often, many users of computers running the seventh and eighth Windows versions It may happen that a cross appears instead of the usual wireless connection icon, indicating that there are no connections available.

Moreover, this happens mainly on a fully working computer. At the same time, up to
At that moment everything was working fine and it was possible to connect to the Internet, but now there is no such option. This problem can occur for various reasons, however, it all comes down to the fact that the operating system does not see the Wi-Fi module and considers it turned off, as a result of which it displays a message about the lack of connections. But this problem can be fixed. There are several methods for this.

If Wi-Fi has not been used on this laptop before, or Windows has been reinstalled

If a wireless connection has never been used on a laptop, and now a Wi-Fi router has appeared and you need to connect to it, but this problem arises, then you need to search the Internet for advice on why Wi-Fi does not work on a laptop.

The main thing that needs to be done in this case is to install all the necessary drivers, which need to be downloaded from the manufacturer’s official resource, but not the driver pack. At the same time, it is necessary to download drivers not only for the Wi-Fi module, but also to maintain the functionality of the laptop keys, which are designed to turn on the wireless adapter.

If your wireless network was working and now there are no connections available

If everything was working fine up to this point, and then suddenly a problem appeared. this problem, then you need to check all the methods described below in turn. You can try disconnecting the router from the electrical network, and then turning it on again. In addition, it is worth trying to use the “Troubleshooting” section, which appears when you click on the Wi-Fi connection icon with a cross.

In addition, you need to check whether Wi-Fi is turned on on the laptop, if it has one, and whether you can turn it on using the function keys. Also worth a visit proprietary program Wi-Fi network management, if available. In addition, you need to make sure that the wireless connection is in the list of connections.

In the “eight”, in addition to all the methods described, you should go to the “Control Panel” and select “Options”. In this section, you need to click on “Change PC settings”, and then select “Network” or “Wireless”, depending on the version. Here you need to check that all modules are active. In 8.1 you need to check if
Is Airplane Mode enabled?

In addition, it is worth visiting the official website of the laptop manufacturer and downloading drivers for the Wi-Fi module from it and installing them. It's worth doing, even if you already have such drivers, it's still worth trying.

If after doing all this, nothing has changed, then you can try another method. It is not the simplest, so for inexperienced users it will not be so easy to complete.

Remove the wireless Wi-Fi module from the device manager and install it again

To open the device manager, you need to press Win+R and enter the command devmgmt.msc, after which you need to click OK. Then you need to go to “Network adapters”. Here you need to right-click on the Wi-Fi module. It is worth checking that there is no “Enable” item in the context menu. If there is one, then you need to use it and not perform the steps described below. If this is not the case, then you need to select “Delete”.

After removing the device from the operating system, in the device manager you need to select “Action” and click “Update hardware configuration”. This will start a search for the Wi-Fi module, after which all the necessary drivers will be installed on it. Perhaps after this everything will start working.

See if the WLAN AutoConfig service is enabled in Windows

To perform this method, you need to go to the “Control Panel”. In this section you need to select “Administration”. After this, you need to click on “Services”. In this section you need to find the “WLAN Auto Configuration” service. If it says “Disabled”, then you need to double-click on it and in the “Startup type” line set it to “Automatic”. After this, you need to click “Run”.
