The tablet does not receive wifi. Android doesn't see any Wi-Fi networks

All modern tablets and mobile devices have a built-in module by default that is responsible for connecting to Wi-Fi. However, the inability to connect to Wi-Fi does not always mean that the module is faulty; sometimes the problem may lie in the software part of the device.

About possible reasons

The tablet and smartphone usually connect to Wi-Fi immediately if the corresponding function is enabled in their settings. Connection may not occur for several reasons:

• There are no available networks nearby;
• You are trying to connect to a password-protected network. In this case, you need to find out the password from it and try again. Most often it will end in success;
• Your tablet may not be configured to automatically connect to unfamiliar Wi-Fi networks. In this case, you need to go to “Settings” and try to manually connect to the desired network;
• Hardware failure in the tablet firmware;
• Failure in the router settings;
• Perhaps the owner of the network to which the device usually connected by default has changed some of its data. In this case, you will need to try to reconnect to it using new data.

In fact, there are not many reasons why a tablet may not see and/or connect to a Wi-Fi network. Some of them you can solve on your own, in other cases you will have to turn to the manufacturer of the device or router for help.

Method 1: Check that your network data is up to date

If you or the owner recently changed any router data, for example, the Wi-Fi password or some protocols in the modem firmware, then you may encounter the problem of the tablet being unable to connect to a wireless network.

Fortunately, this problem solved quickly:

Method 2: Setting the current date

Wi-Fi may not work on the tablet also due to incorrectly configured date and time. However, this very rarely causes problems with connecting to the global network.

The solution is to set the date and time correctly:

Method 3: Contact tablet manufacturer support

If you suspect that the problem is in the tablet itself, then try to get an answer on this issue from the device manufacturer. Perhaps they will recommend you service center or they will tell you which ones additional settings can be done to get rid of the problem.

Let's consider appealing to technical support Samsung:

Method 4: Reset the system to factory settings

This is the most extreme method, which is recommended to be used if you have already tried everything and nothing has helped. It is also worth understanding that if you reset the settings yourself, you lose not only all user information, but also the warranty on the device.

If you still decide to reset the settings, then use this step-by-step guide:

It is worth understanding that the method of resetting the settings to factory settings does not always help. For example, if the problem is in the router or in the hardware of the tablet, then this method will be useless.

Some of the methods discussed will help you find out the cause of malfunctions in the tablet and solve it using tips from the manufacturer. It is also possible that the tablet will have to be returned to a service center.

Often, users do not have problems connecting their tablet to Wi-Fi: they need to visit the appropriate section in the menu, select an access point, and then enter personal data. However, it happens that the tablet does not connect to Wi-Fi, and then there is cause for concern. There may be several reasons for this phenomenon. Below we will consider each problem problem and solutions separately.

It is important to know! In most cases, the reason for the lack of connection to the Internet lies in the settings of the router or the gadget itself. Much less often, connection problems arise due to a non-functional built-in module.

Time and date settings are incorrect

Incorrect time and date settings often cause problems with Internet connection for owners various devices. So, what to do in this case? First, look for opportunities to solve the problem:

1. First, visit the settings section of your personal gadget
2. Now you need to go to the “Date and time” item
3. Configure the correct settings
4. Connect to Wi-Fi networks

If the Wi-Fi network appears, the tablet works - the problem is solved. But what if the device still doesn't work? Continue reading the instructions below.

Password difficulties

It happens that the tablet does not connect to the Wi-Fi network due to the user’s carelessness: he can change Old Password new, but forget to indicate changes in the gadget settings. In this case, the device will connect to the World Wide Web using former password. Is it worth explaining that such intentions of an electronic device will not be successful?

To get rid of complexity, you will need Wi-Fi settings, then deleting the old profile. Reconnect the gadget.

Software glitch

In progress software glitches and malfunctions can also occur, which can also cause the tablet not to see the Wi-Fi network. You can eliminate such a nuisance using a useful utility - Wi-Fi Fixer. In order to take advantage of the program's capabilities, download it to your tablet, then install and launch the application.

The main page is where information regarding connection status is located. The Known item provides information regarding access points ever used to connect a specific device.

Now you will need to reboot your device.

Incorrect device settings

There are other reasons why the tablet does not see Wi-Fi, one of which is the failure of some settings. To forget about this problem, you will need to make a radical decision and reset the settings. This path represents the most radical, most effective option for solving a complex problem.

It is important to know! Before you reset your tablet, you need to do backup copy important information, since they will all be deleted later.

You are required to visit the settings, where you select the “Backup and Reset” tab

The next item that should interest you is “Reset settings”

Now try to find out as much system information as possible that appears on the tablet screen. Confirm the decision and try to connect to the Internet again.

Virus programs

This is another reason why the tablet cannot connect to the Internet. Why is this happening? Many users of Android OS devices tend to think that their gadgets are protected from viruses and malware, but this opinion is incorrect. Of course, it is unlikely that the cause of your discomfort will be a large malware program, but small pests that interfere with the correct operation of the device are not excluded.

In order for your tablet (Lenovo or another brand) to connect to the network, you need to download and install special application for devices running on operating system Android - antivirus. In use antivirus program there is nothing complicated or time-consuming: run the application, scan the device for virus software. If you find suspicious files, follow the instructions that appear on the screen.

Router settings

If your tablet stops connecting to the Internet, a possible cause of the problem may be a problem with the device connecting to Wi-Fi. The tablet does not search for Wi-Fi? Probably not correct settings router. In this case, there is a sequence of actions:

1. Device settings are the area that interests us first. Connect to the equipment wirelessly or using a cable. Find tips on the procedure in the instructions included with your specific router model. Often it is enough to enter 192.168.0.1 in the address bar
2. Now go to the “Wireless Mode Settings” item, where you will need some changes: “Mode” - “11bgn mixed”, “Channel” - “Auto”. Next is “MAC Address Filtering”, select “Disabled”

Most likely, by following the instructions above, you will be able to get rid of the reason why your device does not connect to the Internet. If the gadget still cannot connect to the Internet, we recommend contacting a service center to diagnose the problem and possible repairs.

Your tablet does not see the Wi-Fi network, or the connection fails? Is the signal weak or unstable? One or more problems indicate that there are problems with the mobile device and/or network equipment. To solve the problem, we have prepared comprehensive material where you will find the cause and method of eliminating the breakdown.

How to identify a malfunction

When using the Internet, the chain consists of a provider, network equipment And user device. Therefore for quick solution problems, it is important to determine on which side the malfunction occurred.

Find out if there are any interruptions in the availability of the Internet on the part of the provider. To do this, connect the Ethernet cable to network card computer or laptop. If this is not possible, call your provider and ask if there are any interruptions in the Internet at your address.

Connect another device to the router, preferably with the same Wi-Fi module specification. If other equipment connects and works fully, the problem should be considered in the mobile device.

Connect the tablet to other points Wi-Fi access. An unsuccessful connection indicates problems with mobile device. If the connection cannot be made only with the home router, then the problem must be looked for in the equipment used.

What to do when problems are on the provider’s side

Solution 1: Report the problem to your Internet provider, replace the Ethernet cable

If there is no Internet, report the problem to your service provider. If the breakdown cannot be resolved remotely, call a repairman at home, for example, to replace the Ethernet cable. A reason to think about replacement if you live in an apartment building and the cable is laid outside. It's important to note that most providers have tools to remotely diagnose cable integrity.

Solution 2: Check modem/settings

If the Internet is provided through telephone line, check the operation of the modem. Connect the equipment directly to your PC or laptop, check the connection settings. If there is no result, take the modem to a service center for diagnostics.

What to do about problems with your router

Solution 1: Reboot your router

A router is a miniature computer, so failures and system errors during operation are inevitable. In this case, the problem is solved by restarting the system. It is advisable to turn off the power for 2-3 minutes.

Solution 2: Check your internet settings

For the Internet to work correctly, you must set the correct settings in the management console. This procedure is required if you are setting up the router for the first time. The settings should be rechecked periodically, as failures often lead to settings being reset.

Solution 3: enable Internet distribution via wireless network, DHCP protocol

In the settings, it is important to activate the “router wireless broadcast” and “SSID broadcast” functions. Also enable the DHCP protocol if the option was not previously activated.

Solution 4: Change channel

If the router settings have a fixed channel, it is recommended to change the value or set the mode to auto. If used auto mode, reboot the router to automatically change to a less busy channel.

Solution 5: Switch broadcast band

Some routers allow you to work only in one or two broadcast bands - 2.4/5 GHz. If the frequency range of the router and the tablet do not match, the connection will not be established. Therefore, set the frequency in the router settings that is supported by the tablet.

Solution 6: Disable MAC Address Blocking

Sometimes, when blocking unwanted consumers, it is easy to mistakenly add your own tablet to the blacklist, which will not allow you to connect to the Wi-Fi network. If your router list contains blocked MAC addresses, find out the corresponding value in the Wi-Fi settings. Check the data and, if necessary, remove the MAC address from the blacklist.

Solution 7: Reduce load/temperature

You won’t be able to use a Wi-Fi network if the router is loaded with another connected device – a PC or laptop. Then you need to limit the speed or temporarily stop downloading/uploading information.

Take care of acceptable temperature conditions. If your router is overheating, consider active or passive cooling.

Solution 8: Increase transmitter power

If the access point appears and disappears from the "available to connect" list, or the connection drops after connecting, the transmitter power is likely muted. Open your router settings and increase the transmitter level. If the router antennas are of a replaceable type, install an enhanced version.

Solution 9: Reset router/update firmware

Sometimes viruses and system failures prevent you from changing settings. When changing parameters, the values ​​are saved, and after moving to other settings, they return to their original position, which makes the setting meaningless. In this case, it is recommended to set the parameters manually from scratch.

If the reset did not affect the operation of the router, then it is worth updating the firmware. If there is no result, have the router repaired or think about buying a new device.

What to do if there is a problem with your tablet

Solution 1: Check that the password you are entering is correct

A common mistake when connecting to an access point is the wrong password. By default, the tablet settings are set to “hide password”, which makes it easy to make mistakes when entering. Therefore, it is recommended to allow the display of the password, as well as take into account the case when entering characters.

Solution 2: Reboot the system

Sometimes a system failure occurs in the tablet, which prevents you from connecting to the network, or the connection is successful, but there is no access to the Internet. In this case, restarting the operating system usually helps.

Solution 3: Disable power-saving features

To save energy, most tablets are equipped with power saving modes. Typically, the effect is achieved by disabling modules that actively waste power, including Wi-Fi. Therefore, it is recommended to deactivate the corresponding mode or use a performance preset.

Solution 4: change the broadcast range/turn on displaying networks with a weak signal

If the tablet is designed to work with the 2.4 and 5 GHz bands, it is recommended to set the band to automatic selection. Also, do not use the “hide access points with weak signal” option, because when weak signal router, it will not connect.

Solution 5: change firmware/radio module

Changing the firmware or radio module often helps improve Wi-Fi performance. If problems with connecting to Wi-Fi began after flashing, it is recommended to return the originally used firmware back.

Solution 6: Replace the Wi-Fi module/motherboard

If the above methods are unsuccessful, then replacing the motherboard with a working module will solve the problem. In some tablets, the Wi-Fi module is presented as a separate board. Then there is no need to change the motherboard, just unsolder the old module and solder in a new or used one, but in good condition.

Often it is not possible to find a suitable module. In this case, “implanting” a USB Wi-Fi module helps, as in the images below. One end of the wire should be soldered to the USB contacts, the other to the contacts on motherboard. If there are no markings near the soldering points, you should first find a diagram.

Conclusion

When using the Internet, the chain of participants consists of three links - the provider, network equipment and the user device - a tablet. To quickly resolve connection problems, it is important to determine which link the fault occurred. The article contains detailed methods Troubleshoot if the tablet does not connect to wifi. Solutions are grouped into categories for step-by-step execution and better understanding for beginners and advanced users.

Connecting a tablet to Wi-Fi in most cases does not cause any problems: in the corresponding section of the electronic gadget’s menu, the required point is selected, a password is entered, and Internet access is opened. Along with this, in some cases connection with wireless network becomes impossible for a number of different reasons. After reviewing the information below, you will learn why your tablet may not connect to Wi-Fi and what to do to resolve any problems.

Important note! The root of the problem in the vast majority of cases lies in the settings of the router or the tablet itself, and very rarely the lack of connection is caused by the inoperability of the built-in Wi-Fi module or a temporary shutdown of the router.

Incorrect time and date settings

It is extremely rare that problems with connecting to Wi-Fi occur due to incorrectly set time and date. Start looking for a way out of this situation from this moment. Open the settings section of your tablet and go to Date and time. Set the correct settings and try connecting to Wi-Fi.

If everything is fine, congratulations. Wi-Fi connection not working? Continue reading the instructions.

Password problems

A fairly common case: the user decided to set a different password to connect to Wi-Fi, but forgot to make the appropriate changes to the tablet settings. The device will try to connect to the Internet using the old password and, of course, it will not be able to do this.

To solve the problem, go to your Wi-Fi settings, delete the old profile and try connecting again.

Software settings failure

Connection problems may occur due to a software glitch. There is a good service utility - Wi-Fi Fixer. You just need to download it and install it - no additional settings are required.

On home page information about the connection status at the current moment is provided, in the Known section - information about Wi-Fi hotspots, to which the tablet has ever been connected.

Restart your device and try connecting to Wi-Fi again.

Incorrect tablet settings

Failures in some settings may result in difficulties connecting to Wi-Fi. The fastest, most effective and drastic way to solve the problem is to reset the settings.

Attention! Before resetting, be sure to back up the required files and contacts - everything will be deleted.

In Settings, open the “Backup & Reset” tab.

Select Reset Settings.

Review the proposed system information, confirm your intentions, and then try connecting to Wi-Fi again.
Presence of malicious software

Those who claim that Android is virus-free are mistaken. There are viruses, but most of them are not large-scale malicious programs that make the device’s operation completely impossible, but so-called. “minor pests” that make incorrect changes to some functions.

Download the application (Antivirus for Android). Launch and scan your device for malware. If you find suspicious files, follow the application's instructions.

WiFi router settings

Quite often, problems connecting tablets to Wi-Fi arise due to incorrect settings router. Do the following:

Go to your device settings. To do this, connect to the router via a wireless connection or cable (you can from a computer, laptop, any smartphone or tablet, etc.). You will find connection recommendations in the instructions specific to your router. In most cases, to do this you need to enter 192.168.0.1 in the address bar of your browser;

Go to “Wireless Settings” (the name may differ depending on the brand and model of the router). Make the following changes: “Mode” - “11bgn mixed”, “Channel” - “Auto”. Next, open the MAC Address Filtering tab and select Disabled.

Have you tried all the above methods, but still can’t connect to Wi-Fi? Most likely, the problem is in the tablet's radio module. In this case, you need to contact a specialized service center with a request for diagnostics and repairs.

Sometimes the tablet does not see Wi-Fi for a trivial reason. This could be a difference in frequencies or a cache buildup in the device. If the tablet does not see home network Wi-Fi, then first try rebooting the device. Typically, an overloaded gadget may simply not connect to the network due to garbage in the memory. You don’t need to think that if you can’t see Wi-Fi, then it’s a matter of build quality.

The tablet does not see Wi-Fi - the main reasons

There are several main reasons why the device does not connect to the network. First, we will list them, and then we will analyze each case separately. So, the reasons:

• Frequency difference between modem and planet;
• Hardware problem – a malfunction in the tablet’s hardware;
• The problem is in the router settings;
• Software failure (tablet, modem).

It is not necessary that there be only one reason. Sometimes they are combined. But in any case, you should act carefully, excluding possible reasons. If your tablet stops seeing Wi-Fi, then first do a small test. Check that it doesn’t see your router, or any other source either. This way you will understand where the fault itself is – in the tablet or in the modem.

Why doesn't my tablet see Wi-Fi?

We have already written about the difference in frequencies. Please note that the device and source may operate at different frequencies. Please clarify this point in the parameters. If this is so, then the question disappears. Also, the tablet does not see the Wi-Fi network due to incorrect router settings. You can configure the modem yourself, or contact your provider. As for the software failure, first try rebooting the device and router.

You can read about us on the website. If the tablet does not see any Wi-Fi network, then try to get rid of the cache. Rebooting often helps. Finally, all the fuss may be due to problems in the tablet’s hardware. This can cause the tablet's Wi-Fi unit to fail. Possible oxidation on the contacts to the signal receiver. And problems with the antenna are quite possible. If you can work with a tester, then you need to open the device and check the contacts (search for short circuits).

Why doesn't the tablet see Wi-Fi or sees it but doesn't connect?

Why does my tablet see Wi-Fi but not connect to the Internet? There could be two reasons for this. Different frequencies or a problem in the router settings. The same can happen if the tablet does not see the operator’s network. Now you know why the tablet does not see Wi-Fi. In the next post we will look at the topic - why the phone stopped seeing wifi networks. If you have any questions, ask.
