The tablet does not connect to Wi-Fi, what should I do? About possible reasons. Software settings failure

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 the provider, network equipment and the user device. Therefore, to quickly resolve 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 an Ethernet cable to the network card of your 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 your tablet to other Wi-Fi hotspots. An unsuccessful connection indicates problems with the 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 a replacement if you live in 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 a 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 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 “wireless router 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 you use automatic 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 lists 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 what is 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 a reinforced 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 does not allow you to connect 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 if the router’s signal is weak, you will not be able to 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.

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 the 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 troubleshooting methods 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.

We live in a time when almost any operation can be performed using a smartphone or tablet. When you can find absolutely any information on the Internet in a matter of seconds. When, sitting at home, at work, or even while on the road, you can listen to any music or watch any video ever uploaded to the network. What can baffle or frustrate us most these days? Only that moment when, unexpectedly for us, the phone or tablet does not connect to Wi-Fi, and we are unable to access the Internet. Why sometimes a phone or tablet does not connect to Wi-Fi, why errors occur when trying to connect and how to deal with them, we will look at in this material.

There can be many reasons why the device does not connect to the wireless network.

It’s worth clarifying right away that this small collection of guides is of equal value both for those who access the network using a phone and for those who use a tablet for these purposes. The Wi-Fi module in these devices works identically, so if problems arise when connecting to the Internet, the solution is most often the same for all users and devices.

Most often, Android users have problems connecting to the network, but the system itself provides much more information about a particular problem that arose during the connection. That is why we will look at problems connecting to Wi-Fi using Android as an example.

When a user connects to Wi-Fi, an Android phone may display error messages containing various text. It is this text that will help us determine why the device cannot connect to the Internet, and will also help us eliminate the cause of this problem.

After selecting one or another access point, the phone may show the following messages:

• “Obtaining an IP address...”
• "Authentication..."
• "Disabled."
• "Saved, WPA/WPA2 security."

There is also a situation where the connection was successful, but the pages still cannot be opened.

In the case when an Android phone or tablet does not connect to the Internet via Wi-Fi and constantly reports only that an IP address is being obtained, the simplest thing you can do is to delete the network and its settings from the device’s memory and try to connect again. To do this, click on the name of the access point in the device settings and select the “Delete” option in the context menu. After a few seconds, try connecting again. In this case, your phone or tablet will require you to enter the password again, so if you are not connecting to your home router, you should check in advance that the password is spelled correctly.

Authentication

The reason why an Android tablet or phone may constantly display such a message is most likely due to the password. First, you need to make sure that you entered all the password characters correctly and did not make a typo anywhere. If the Internet does not turn on for quite a long time, displaying a similar message, remove the network as stated in the previous paragraph of the instructions and try to connect again. Secondly, if this is not your first time connecting to the selected Wi-Fi network and the connection previously occurred without problems, you should check to see if the password has changed since the last successful connection. This is relevant for cases when a smartphone or tablet is not connected to home Wi-Fi.

Problems not related to the mobile device

All subsequent tips that we will give you in this material are in one way or another related to router settings, so they will be relevant primarily in the case when your tablet or smartphone experiences difficulties connecting to the network directly at your home. That is, where you can independently change the settings of your network equipment.

First, you will need to find out why your gadget does not work with the selected access point, why it refuses to connect to it, and then change some of the router’s settings by logging into its control panel through any browser or through a mobile application, if provided by the manufacturer.

If your Android tablet or smartphone cannot connect to the Internet in your home, there may be a simple reason for this. Even though the router may appear to be working visually, its software may be frozen. In this case, a reboot will help. Unplug the appliance and wait a few seconds (7–10). After that, plug it back into the network and make sure it works by checking the indication. After a few seconds, check if your mobile device can see the access point and try connecting again. If the gadget does not see the network, most likely the router is still turning on and you need to wait from a few seconds to a minute.

Change Password

If your gadget sees an access point, but you cannot remember the password for your wireless network located at home, you can change it at any time in the router settings. To do this, go to the appropriate settings section and set a new symbol combination. There must be at least eight of them. Save the changes and reboot the router. Please note that after this procedure, you will need to enter a new password into each device that works with this access point and receives a wireless signal through it.

Changing the encryption type

In some situations (this is especially true for budget-class Android devices), it may turn out that the built-in Wi-Fi module does not work with certain types of encryption. This leads to the fact that the device sees the access point, but only displays the “Disabled” error and does not connect to the Internet. To fix this problem, you will need to open the settings of your router and change the type of encryption with which your mobile device works. We recommend choosing between WPA/WPA2 and WPA-PSK types. These encryption standards are supported greatest number devices.

Change channel

For some situations in which a mobile gadget does not connect to the Internet via a wireless network, it will also be useful to change the channel through which the signal is heard. The reason for changing the channel may be a situation when the device sees the access point, but the connection does not occur. This is also due to compatibility issues between network equipment and the Wi-Fi module. In total, in the router settings you will find up to 12 channels, but, as a rule, not a single budget Android gadget works with a channel higher than the ninth. Consider this information when setting up your network.

Disabling MAC and IP filters

In a situation where the network equipment has been tested and is functioning correctly, the mobile gadget sees the access point, several similar devices access the network through the same device, but the smartphone still does not connect to the target network, it is worth looking into the MAC and IP address filter in the parameters router. Sometimes network equipment is configured in such a way that only specific devices located in your home, whose MAC and IP addresses are registered in a special section of the control panel of the modem or other network equipment, can gain access to the Internet. Disable all unnecessary filters and restart the router. Don’t forget - it turns on from a few seconds to a minute, and only after that you should check whether the access point is visible to the mobile device.

Conclusion

As you can understand from our short instructions, almost any problem that arises when connecting a mobile device to a wireless network can be solved in a couple of minutes, having the necessary information and access to the network equipment settings. We hope that our instructions helped you eliminate errors and now you can easily access the Internet from any of your gadgets. If this still doesn’t work out, we recommend going through the entire list from beginning to end and trying to use all the tips without exception.

Once you get your tablet, you'll likely want to use wireless connectivity. Often, users find themselves in a situation where the device does not see the network or displays a number of errors when connecting. In this article we will look at the most common problems that arise when accessing the Internet and ways to solve them.

Why doesn't my tablet connect to the wireless network?

1. Entering the wrong password

The most common reason for wireless Internet failure on a tablet. Most often it occurs if the user has changed the password, but the Android device has never connected to it. Enter a new password and check if your device connects to the Internet.

2. Viruses

Sometimes the reason why your device won't connect to the Internet can be due to malware. To fix this problem, you need to scan the gadget with an antivirus.

3. Power failure

Inexpensive routers are characterized by unstable operation. Voltage surges can lead to the tablet not seeing the network. To solve the problem, reboot the router by disconnecting it from power for 2-3 minutes. Then turn it on again. Sometimes a reboot needs to be done several times.

4. Wrong encryption type

To check the encryption type, go to the router settings. To do this, enter the router's IP address in the address bar of your browser. This data can be found on the device sticker or in the instructions. In the tab that opens, select “Advanced settings”. Then, under Wi-Fi, click Security Settings. To view the encryption type, go to the “Network Authentication” menu. From the proposed options, select WPA-PSK\WPA2-PSK2 mixed. Reboot your router. 5. Time and date settings are incorrect

In some cases, the tablet does not connect to the wireless network due to incorrect date and time values. After correcting these parameters to the correct ones, network operation will resume.

6. Checking the MAC filter mode

Another reason why a user on a tablet does not see Wi-Fi may be changes in MAC address filtering settings. To exclude this option in the router settings in the “Wi-Fi” section, go to the “MAC filter” item. Check which mode is selected. The following values ​​are possible:

• Disabled – by default, there is no restriction for MAC addresses.
• Allow – access to the wireless network is allowed only to those devices whose MAC addresses are registered on the corresponding tab. Other devices are not allowed to access the Internet.

Deny – there is a list of MAC addresses that are restricted from accessing the Internet. If the router sees a prohibited MAC address, it closes the Wi-Fi connection for this device.
If the “Allow” or “Deny” modes are selected in the router settings, check whether the MAC address of your device has access to the wireless network. Or change the mode to Disabled. After these manipulations, check how the gadget connects to the network.

7. Channel diagnostics

If the tablet sees the network but does not connect to it, check the channel matches. This problem occurs when the signals of two routers operating on the same channel intersect. There is interference that prevents access to the wireless network.

Check on your tablet to see if there are other wireless networks nearby. If your neighbors have Wi-Fi, then perhaps your routers operate on the same frequency.

To change the channel in the router settings, go to the “Wi-Fi” section to the “Basic settings” tab. Find the “Channel” line, try choosing a different value.

Reboot your router.
If the channel is set to “Auto” mode in the settings, the router itself will search for an available free channel and use it. Therefore, in most cases it is recommended to use this mode.
8. Changing Wi-Fi version

The reason why the tablet does not see the wireless network may be that it does not support the wireless version that is installed in the router settings. On the “Wi-Fi” tab, go to “Basic Settings”. In the “Wireless mode” line, enter 802.11b\g\mixed. In this mode, the router provides Internet access for all types of devices.

Today it is already obvious to everyone that if a tablet or smartphone does not connect to the Internet via WiFi, then the user immediately loses most of the entire functionality of this device. Connecting a device to a wireless network is usually not accompanied by difficulties; you just need to turn on the Wi-Fi adapter built into the gadget and then connect to the selected access point by writing a password.

However, sometimes Wi-Fi, that is, accessing the Internet via Wi-Fi, does not work due to some problems. Below are the most common reasons, why the tablet does not connect to WiFi, and specific recommendations are given on what to do if the owner of the gadget is faced with such a situation, using the example of a Lenovo tablet that does not connect to the WiFi wireless network. WiFi on a tablet computer sometimes does not turn on, both due to problems in the device itself and due to network equipment failures.

Owners of Lenovo gadgets very rarely encounter WiFi problems in the device itself, but if this function does not work, then it happens that many causes of problems are very quickly resolved by the users themselves by simply adjusting some settings.

It is important to write your password carefully

Very often, the tablet owner himself is the culprit for why a fully functional device does not connect to a wireless access point. There are many cases when Wi-Fi on the tablet does not connect due to incorrect writing of the network access code. Nowadays, it is very common to set up Wi-Fi network security, for example, using Wpa2 security. It is recommended to check the “Show password” line when dialing the access code. This ensures that the password is written correctly in most cases.

If you are absolutely sure that you entered the exact password, but the Internet cannot turn on, you must first check the operation of the router. Often difficulties arise due to incorrect router settings, overload, power surges, etc.

Restarting the router

If a tablet or smartphone from Lenovo or another brand does not connect to the WiFi wireless network, a message about this is immediately displayed on the display. The router that the user intends to connect to needs to be restarted. In most cases, after this procedure, the Internet begins to function normally on the device.

Analysis of the security system of a protected Wi-Fi network

When a gadget cannot establish a connection with the router and at the same time it says saved in the status bar, then we can draw a conclusion about the devices used by the router and the device. various types coding.

The following sequential steps must be performed:

MAC address settings

Most often, errors when filtering MAC addresses appear when tablets from Lenovo and Asus manufacturers work with cheap router models. In order to ensure maximum security, these gadgets determine the MAC address and if it is not detected, the access to the global network is blocked, which is often a problem why network access in the tablet does not turn on.

The following steps need to be taken:

If the problem cannot be successfully resolved, then you need to try temporarily turning off filtering in the “Network” tab.

And restart both devices.

Checking channels

If there is no positive result after completing all the steps described above, it is recommended to configure the channels.

1. To do this you need to do the following:
2. Enter the router settings;
3. Next, restart the router and tablet computer;
4. Make an attempt to connect.

If all attempts fail, you will have to resort to resetting your tablet PC.

The connection mode is set incorrectly

It happens that the router and tablet use various modifications of Wi-Fi communication. In this case, the device does not detect the version used by the router.

There is the most popular connection version 802.11n, as well as with the prefix “b” and “g”.

The following steps must be taken:

1. Open the router settings menu;
2. View the connection version and, if necessary, change it to the one corresponding to the tablet software;
3. Restart devices;
4. Test the functionality of all modes.

Technologies do not stand still. Mobile devices, with which you can easily and quickly access the Internet, are an integral part of every modern man. But what is a tablet without Wi-Fi? Just a piece of plastic and metal. Unfortunately, it often happens that the tablet does not see Wi-Fi. Next, we'll look at why this might happen and how to fix these problems.

Some general information

First, you should understand that Wi-Fi technology has different standards and protocols. That is, today there are many different versions of Wi-Fi. However, only three standards are used in everyday life:

1. 802.11b is the oldest standard, which operates at 2.4 GHz and has a maximum throughput of up to 11 Mbps.
2. 802.11g is a standard that was approved in 2003. Allows you to achieve data transfer rates of up to 54 Mbit/s. Operates at a frequency of 2.4 GHz.
3. 802.11n is the fastest wireless communication option, which allows you to achieve speeds of up to 300 Mbps. This standard operates at a frequency of 5 GHz.

As you can see, some of the standards operate at different frequencies. This means that one of the reasons why the tablet does not see Wi-Fi may be due to frequency differences. That is, if the router only operates at a frequency of 5 GHz, and the tablet only supports 802.11b or g mode (2.4 GHz), then it is not surprising that the gadget cannot see the access point. There's nothing you can do about it here. Just check its technical specifications when purchasing a tablet.

It should be noted that many modern routers can operate in mixed mode. That is, in the Wi-Fi settings in the router, you can select the 802.11bgn mode. This means that the access point will distribute the network on two frequencies at once, so that both old and new mobile devices can connect to it.

Weak signal

Don’t forget that different tablets, like routers, have different antennas. The access point may have a weak antenna, which means it can cover a fairly small area. At the same time, some tablets, due to the nature of their design, may have a weak antenna, which is muffled by the metal case, which is why the reception will be very weak.

If, for example, a laptop has an antenna that runs around the entire screen, then, of course, the signal level will be very strong. But if the antenna itself in the tablet is much smaller, and is also covered with a metal cover, then the reception signal will be insufficient. This is another reason why the tablet does not find the Wi-Fi network.

In this case, you should move closer to the router (get close) and check if the tablet detects this access point. If it does, then the problem is a weak antenna. In this case, you can try to strengthen the antenna. But you will do this at your own peril and risk, since not all methods are simple and safe.

The problem may lie elsewhere. In this case, the source of difficulties can be both the router itself and the access point to which it is trying to connect.

How to identify the problem

Often the tablet does not see Wi-Fi due to the fault of the access point itself. One of the reasons was described above (difference in supported frequencies). But sometimes, in order to secure their home network, owners hide the access point. Therefore, first of all, you should go to the router settings and check whether wireless mode and whether the network is hidden. All this is checked in the Wi-Fi settings in the router.

If you uncheck the first line (“Enable wireless broadcasting”), the router will not distribute the network at all. If you uncheck the second line (“Enable SSID broadcast”), the network will be hidden. That is, Wi-Fi will be distributed, but devices will not see the network name. You must connect to such a network manually.

If everything is turned on in the router settings, then it’s worth checking whether the tablet can see at least one network at all. This is done simply. Just go to your friends' house or to a cafe that has Wi-Fi, and so on. If your tablet sees other networks, then the problem is with your router. If the tablet does not find a Wi-Fi network anywhere at all, then the problem is with the tablet.

Solving problems on the router side

We have already discussed the basic settings of a Wi-Fi router above. That is, you check what Wi-Fi mode the router uses, as well as whether wireless broadcasting is turned on and whether the network is hidden. If all these parameters are in order, then you will not be able to configure anything else. In this case, you should reboot the access point. Simply unplug your router for 7-10 minutes and then plug it back in.

If after this the tablet still does not see the Wi-Fi network, then you should reset the router to factory settings. If this does not help, you will have to update the software, since, most likely, there was some kind of malfunction in the system. You can find instructions for updating the software, as well as the firmware itself, on the official website of the router manufacturer. If even updating the software does not help, you will have to buy a new router. When choosing, pay attention to what Wi-Fi modes and standards the access point supports.

The problem is on the tablet side

If you determine that the problem lies specifically in the tablet, that is, it does not see any network at all and does not access the Internet even in close proximity to access points, then there are several options.

First of all, you should simply reboot your device. The fact is that due to the accumulated cache (garbage), the tablet may not turn on the wireless adapter at all, which is why the search for networks does not even begin. That is, the tablet does not receive Wi-Fi. A reboot resets the cache and restores minor system glitches.

If this does not help, then you should move on to more drastic measures. It’s worth saying right away that the Android system is designed in such a way that there are no settings like on a PC. You cannot reinstall Wi-Fi adapter drivers, reset network settings, or configure the network adapter. Connection to networks occurs automatically. Therefore, if none of the above helps, then you will have to do a factory reset.

Another reason why the tablet does not receive Wi-Fi may be that the antenna terminal came off as a result of a fall (probably, there is no such tablet that has never fallen). Also, the contacts could oxidize due to high humidity or, if the device was disassembled for repair, then during assembly the technician could simply forget to connect the antenna. In this case, you need to disassemble the gadget: check whether the antenna is connected and clean the contacts.

Of course, such reasons arise extremely rarely, but they are still worth considering. Also, do not forget that sometimes, due to intensive work, the network adapter may simply burn out. You won’t be able to check this at home, and without such an adapter, the tablet, of course, will not be able to access the Internet. Therefore, if you have tried all available measures and nothing has helped fix the problem, it is time to take your gadget for repair.
