A tablet computer is an incredibly convenient invention. With it, you don’t have to be tied to your workplace, as is the case with stationary computing systems, and you also don’t have to carry around extra pounds in the form of a full-size laptop. However, without access to the Internet, the tablet significantly loses its flexibility of use. However, this applies to all mobile devices. In light of this, it is quite clear that if the tablet does not see WiFi, then such a problem should be solved immediately.
Connection procedure
Number of tablet computers running operating room Android systems, tens of times more than their counterparts controlled by the corresponding Windows version or iOS. That is why this article will focus specifically on mass-produced devices. People who are encountering Android-based devices for the first time cannot always use wireless communication correctly. And since in normal state the Wi-Fi module is turned off, beginners have a question: “Why doesn’t the tablet connect to WiFi?” It's actually quite simple. The process of joining an existing wireless network includes several mandatory steps:
- using the transceiver module of the tablet computer;
- scanning the range and selecting the desired SSID name from the list;
- secret combination set.
If the network to which you are connecting is open (Free), then the last point is not required.
How to connect a tablet via WiFi
You need to open the “Application Menu”, which is available on any Android device. Typically, to access it you need to click on the circle icon at the bottom of the screen. Next, carefully look through all the icons and find “Settings”. After clicking on it, a window will open where there is a “Wireless Networks” section.
If you select the WLAN item, you will see an “Off/On” switch. When turned on, it will automatically scan frequencies and display a list of detected networks. You can also see if password access is used and where exactly. If the network is open, then just click on its name and the tablet will connect to it. In case of security (WEP/WPA/WPA2), when you try to join, a password request window will be displayed. By specifying it and clicking the corresponding button, you can link mobile device with the network.
There are more quick way Wi-Fi access. There is no need to search for “Settings” to do this. Just slide your finger down the screen, pulling the curtain, find the WLAN (Wi-Fi) image and click on it. The module will be activated, scanned and a list of networks will be displayed.
Nuances of the alternative method
Nowadays, many Android device owners often replace official firmware custom (made by craftsmen). As a result, not all functions work as usual. For example, if you use a call through the curtain, the tablet often does not see WiFi. The list of detected networks is simply not displayed.
Therefore, in such cases, it is necessary to enable the Wi-Fi module through “Settings”. When using, be aware that some of them have recognized networking bugs. At the same time, in the newest “self-written” software updates often integrate the latest versions Wi-Fi drivers. The conclusion is simple: before studying a lot of information about why the tablet does not connect to WiFi, sometimes it is enough to change the firmware.
The problem of standards
In order for devices to be combined into wireless network, it is necessary that the protocols they support are compatible with each other. Thus, the first models of Android tablets may simply not “know” how to work with WPA2 security, supporting only WEP. In this case, changing the encoding type in the router settings can help. Another thing is also true: a “clumsily” configured access point can ruin the life of the most patient owner of a modern tablet.
Interim solution
So why won't my tablet connect to WiFi? There are many reasons. We have indicated the simplest ones above. In addition to them, the tablet’s ability to work with a wireless network is affected by the power of its transmitter.
Very often, when scanning, the desired SSID is determined, and even a password is accepted, but it is impossible to work with such a connection. This occurs due to the fact that, although the device “sees” the router, the data packets sent do not reach the recipient. The solution is simple - physically move closer to the access point. This “disease” often affects inexpensive transmitters that use cheap transmitters.
A crutch program
But what to do if without apparent reason Has your tablet stopped connecting to WiFi, although until recently everything was working fine? You can try to use the wonderful software solution, distributed free of charge in the Market, is Wi-Fi Fixer. After installing the application, the tablet must be restarted, and the subsequent connection to the network must be made through the interface of this program, which will be displayed in the curtain. In addition, sometimes it helps solve problems with transmission speed.
Working with settings
When figuring out why the tablet doesn’t connect to WiFi, we can’t help but mention possible failures in the most operating system. Installation third party applications, making changes to the operation of components, obtaining root rights - all this can affect Wi-Fi. You can try to restore functionality by returning to factory settings. To do this, go to “Settings - Personal Data” and enable “Backup and Reset”. In this case, all user data (including the phone book that has not been saved to a file) will be erased. Therefore, you must first prepare copies.
If this does not help, it means that the fault lies in the hardware and cannot be fixed at home.
Of course, on the Internet you can find videos and descriptions of how the owners of a non-working device “baked” Wi-Fi modules in the oven, after which they came to life. But this method is not a panacea, and it cannot eliminate all problems. On practice, regular user creates even more damage when trying to disassemble the tablet, not to mention successful repairs using “folk methods.” So, if the hardware breaks down, a visit to the service center is necessary.
The main reasons why wifi does not work on a tablet
After the “opening”, the specialist will announce the cause of the breakdown. It could be:
- Natural wear of the module: in this case it simply changes to a similar one.
- The cable connecting the wireless communication module to the system board tablet. In this case, it must also be replaced.
- Water getting inside the housing. This is an extremely dangerous situation, since after Wi-Fi, other equipment may also fail.
All these problems can be easily resolved by service center employees. The sooner you seek help, the better it will be for you and for the tablet.
In this article we will talk about such a common problem, what to do if the tablet does not connect to a wireless WiFi network. This is a hot topic today, as tablets are widely used all over the world. In addition, problems with connecting to wireless networks appear quite often and not everyone is able to solve them on their own.
So, when talking about a wireless network, you should understand that we are talking about a WiFi router or other access point. It is worth noting that for security purposes, such connections require entering a key. This means that the first thing you should do if your tablet does not connect to the WiFi network is to check that you entered the password correctly.
As mentioned above, the most common mistake is an incorrectly entered password.
However, there are other problems related directly to wireless equipment and its settings. These include the following:
- A MAC filter is installed in the router settings.
- The router is malfunctioning.
- Encryption type mismatch.
- Channel mismatch.
It’s worth noting that you don’t need to configure anything on the tablet itself. Everything that can affect the connection is contained in the router settings. This is where we will go to troubleshoot problems. And first of all, you should pay attention to the fact that budget routers such as TP-Link, D-Link. Asus, Zyxel and so on are not highly stable. They have a tendency to freeze.
This can happen for many reasons, for example, due to power outages, heavy load (if you download large amounts of information at high speed), as a result of connecting a large number of subscribers, and so on. In any case, you should reboot the router. How it's done. It's simple. Unplug the device from the power supply and wait 7-10 minutes, then turn it on again.

Checking the encryption type
If the tablet does not connect to the WiFi network and says “Saved,” this indicates a mismatch in encryption types. First of all, you should know that modern WiFi devices support WPA-PSKWPA2-PSK2 mixed encryption type. If you select a different mode on the router, then the tablet is easy to connect to. In other words, the tablet sees the WiFi network but does not connect to it.
So, we need to go into the router settings. To do this, we connect to it using a laptop (via WiFi or via cable). Next, open any browser and write the router’s IP in the address bar. The necessary data is available on the device itself or in the instructions. If you do not have a manual, there is no data on the router case, then open the command line. To do this, simultaneously press the Windows + R keys, in the window that appears, write CMD and press “Enter”.
In the menu that opens, write the IPCONFIG command and press Enter. Now you need to find the line “Default Gateway”. This is the data we need.
As a rule, this is 192.168.0.1, but depending on the router model, these values may differ. So, we enter the received data in the browser, after which the system will ask you to enter your login and password. We write admin, admin respectively.
How to easily find out the IP address of a router: Video
Here we are in the router settings menu. It is worth noting that the interface may differ depending on the device model. There may also be differences in the names of some sections. Let's consider further actions using the example of the D-LinkDir-615 router.
In the router settings at the bottom of the screen, click the “Advanced settings” button. We find the section under called WiFi. Here we click “Security Settings”. Here the first line “Network Authentication” is the encryption type. Select from the suggested options WPA-PSKWPA2-PSK2 mixed and apply the changes. After this, reboot the router.
Articles on the topic
Often a similar error occurs when the authentication type is correctly set. In this case, rebooting the router will help you. As mentioned above, budget models are not stable in operation.
Checking the MAC filter
The answer to the question why the WiFi network on the tablet does not connect lies in the MAC address filtering settings. The fact is that to increase protection, a special function is enabled that determines the physical address of the computer, opening or closing access to it. To check this, go back to the router settings. In the WiFi section, select "MAC Filter".
To avoid problems in the future, you should turn off filtering.
But if you don’t want to do this, then we do the following. First, let’s look at which mode is selected:
- Allow - the router allows access only to the specified devices.
- Deny - the router blocks network access to the specified tablets.
Now all that remains is to find out the physical address of your tablet and check if it is on the list and, if necessary, add or remove it.

Checking channels
If you have turned off filtering, but the tablet still sees the WiFi network, but does not connect to it, then you should proceed to the next step. This problem often occurs due to channel mismatch. So let's go back to the router settings and try to change them.
To do this, return to the access point settings and in the WiFi section select “Basic settings”. Here we need to find the “Channel” line. Try changing it to something else. It should be noted that it is recommended to set the mode to “Auto”. Thanks to this, the router will automatically use the most suitable channel.
1. Authentication error
This problem is one of the most common, but easily solved.
Solution: enter the correct password
Yes, dear readers, this error is due to an error in the password. Try to check the correct spelling, case of letters and whether you are connecting to the same network for which you have the password.
2. Can’t find a Wi-Fi point
The root of all evil is the discrepancy between the data transmission mode used by the device and the router standard. Modern routers can use three modes for communication: 802.11b, 802.11g, 802.11n. True, Wi-Fi of mobile gadgets usually functions only in one of them. If the tablet works with the 802.11b version, and the network, for example, with any other, then it simply will not see it.
Solution: change the broadcast standard
Fortunately, in most cases you don’t even need to know which operating mode is set in your device. Any router also contains a fourth standard, which is called 802.11b/g/n mixed; it combines all three options into one. When using it, any device will connect without problems and will delight its owner with access to the Internet.
In a nutshell, I’ll tell you how to set up an access point. To do this, you will need a computer that is already connected to the network you need. Type 192.168.0.1 or 192.168.1.1 into the address bar of your favorite browser, this will bring up the router page, which will require a password and login. Typically, the word "admin" is used on both lines. Once in the user interface, you need to find the item with control, there will be an option to change the mode of the wireless module.
3. Can't get network address
There may also be a situation where the device sees the access point, but cannot connect to it.
Solution: specify a static IP
In the list of available connections, find the one you need, then press and hold it until a pop-up menu appears. We are interested in the “Change network” item in it.
Check the box " Extra options", and then change the "DHCP" parameter to "Static" in the "IPv4 Configuration" column. True, that’s not all, check that the code in the “IPv4 address” item fully corresponds to the bottom column “Gateway”, except for the last number, you can come up with it yourself, but only in the range from 2 to 255. Don’t forget to check that everything numbers are separated by dots, like in this example: “192.168.1.128”.

Today, wireless networks help you stay out of sight and constantly stay connected, opening access to the Internet and providing a reliable connection with various devices. And although Wi-Fi has almost reached perfection during its existence, it still remains a rather capricious type of communication. The problems that arise in this regard are almost identical for phones, computers and tablets. Most often, this is a network without Internet access, there is no access to sites when connected, and the phone or tablet does not connect to the Wi-Fi router.
Today, wireless networks help not to fall out of sight and constantly stay in touch, opening access to the Internet and providing a reliable connection with various devices. And although Wi-Fi has almost reached perfection during its existence, it still remains a rather capricious type of communication. The problems that arise in this regard are almost identical for phones, computers and tablets. Most often, this is a network without Internet access, there is no access to sites when connected, and the phone or tablet does not connect to the Wi-Fi router.
How to properly connect your tablet to a Wi-Fi router? To do this you need to do the following:
1. Check Wi-Fi settings on the router itself, making sure that the wireless network is activated and the DHCP server is connected. This will avoid the need to register an IP address each time you connect.
2. Go to the tablet settings, turn on Wi-Fi, hold down the “WI-Fi” icon for a few seconds and go to the wireless network settings.
3. Select a router from the list of available networks (enter a password if necessary).
4. Click “connect”.
If for some reason there is a need to manually enter IP settings, you must check the “additional” box. This will open access to advanced settings. Then, opposite “IP settings”, select “custom”. In the window that opens, you must specify the IP of the router, which will act as a DNS server in this subnet. After that you can connect.
If you did everything correctly and samsung tablet or the other does not connect to the wifi router, then there are several ways to solve this problem.
If your tablet does not connect to Wi-Fi before contacting a service center, you can:
1. Check if Wi-Fi is connected on the tablet itself.
2. Check if power is supplied to the access point.
3. Check whether the function of filtering devices by MAC address is activated in the router settings.
4. Connect to an open access point after first disabling WPA encryption.
There are situations when the tablet “loses” connection with a Wi-Fi point. Of course, this is a rather unpleasant situation for every user. As a rule, this happens at the most inopportune moment. Several recommendations will allow the user to cope with this problem on their own.
If the connection between the tablet and the Wi-Fi point is interrupted, you can:
1. Switch to another Wi-Fi point. If after this the problem disappears, then the cause of the trouble lies in your access point. In this case, you can change the network settings or update the firmware of the connected device.
2. Connect to any other open access point, for example, to a neighbor’s or select a less used channel.
3. The reason may be the device adapter. In some cases, a faulty adapter creates interference, which causes the “loss” of communication between the router and the tablet.
We hope that these recommendations will allow you to avoid the situation when the tablet does not connect to the wifi router zyxel, Rostelecom, Beeline or Asus, and if such a nuisance happens, deal with it yourself.
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, as well as specific recommendations on what to do if the owner of the gadget is faced with such a situation, using an example Lenovo tablet, which does not connect to wireless WiFi networks. IN tablet computer Sometimes WiFi 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 password accurately, 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
In case the tablet is either Lenovo smartphone 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. These gadgets are designed to provide maximum security determine the MAC address and if it is not determined, then exit to global network overlaps, which is often a problem why network access on 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.
To do this you need to do the following:
- Enter the router settings;
- In the “Chanel” item, change the value (it is advisable to try all possible values). After specifying one of the modes, be sure to click “Save”;
- Next, restart the router and tablet computer;
- 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 are most popular version 802.11n connections, as well as with the prefix “b” and “g”.
The following steps must be taken:
- Open the router settings menu;
- View the connection version and, if necessary, change it to the one corresponding to the tablet software;
- Restart devices;
- Test the functionality of all modes.
After purchasing a tablet, you will most 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, and Android device 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 may 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 version wireless communication, which is set 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.
The tablet does not connect to WiFi not only when there are problems with the network. Perhaps the problem lies with the tablet itself.
Let's look at how to solve the problem that has arisen.
Users of Android tablets quite often encounter non-working WiFi. You can solve almost all the causes of the problem yourself.
Incorrect password entry
One of the most common mistakes is the user's fault - entering the wrong password.
If you don’t know why you can’t access the Internet via WiFi, when entering your password, click on the “show password” checkbox to make sure that all letters and numbers are entered correctly.
If you are entering your passcode correctly, you should consider the following: possible reasons breakdowns, which are presented below.
There is no need to make any adjustments to the tablet itself, this can only aggravate the situation.
All actions will be carried out exclusively with the router.
Problems with the operation of the router may occur due to its incorrect configuration, when too many subscribers are simultaneously connected and using the device, power outages and other problems.
Disconnect the router from the network for a few minutes and then turn it on again, this method can also solve the connection problem.
Checking the encryption algorithm used
If your tablet does not connect to the router, and the status bar says saved, the problem is due to different types of encryption that the tablet and router use.
If more than new mode encryption than on a tablet, the user will not be able to pass authentication, thereby making it impossible to access the Internet.
This problem is common on Samsung and Lenovo tablets.
Follow the instructions to configure the same encryption types and resolve the issue:
- Enter your router settings. To do this, you need to connect to it using your personal computer or laptop;
- Open your browser;
- Enter the router's address in the address bar and press Enter (the IP address is indicated on the back of the router panel or in the instructions).
If you do not find such data, then remember that the router, depending on the manufacturer and model, can only accept one of two local hosts: 192.168.1.1 or 192.168.0.1;
- To accurately see the local IP, go to the command line and enter the IPCONFIG command in it.
Find the field called “default gateway” and look at its value in the right column - this is the local address of the router in home network. An example of working with the command line is shown in the figure below;
- Enter the found address in the browser;
- Enter your browser admin username and password. You can view your login information in the instructions for the device (router);
- On the tab quick settings Check the type of encryption your router is using. Set the type to the same as on your tablet. The type of encryption that the Android device uses is indicated under the name WiFi in the connection window.
An example of viewing the type of encryption that the router uses is shown in the figure below;
If you set all the settings correctly, device authentication will proceed normally, and you will find that the tablet sees the network and connects to it.
MAC filter
Incorrect filtering of so-called MAC addresses is another common cause of errors when connecting an Android device to a router.
As a rule, the problem occurs on Asus and Lenovo tablets during their interaction with inexpensive budget versions of routers.
To increase the level of connection security, you need to determine the Mac address - the physical address of the computer on the Internet.
If this address is not determined for some reason, the router closes access to the Internet.
This may be the reason why the tablet stopped connecting and an error appeared.
To adjust your MAC address settings, follow these instructions:
- Go to your router settings. How to do this is described in detail in the previous instructions in the article;
- Go to the “Network” tab. The names of the tabs may differ depending on the model of the router used. In the “Network” tab, make sure that the MAC addresses of the device and computer are identical;
- Click on the save button, reboot the router and device;
- Connect to your router again. Everything should work stably.
Important! You can find out the physical address of the user's tablet on the manufacturer's official website or in the instructions for the device. Physically, an address is a unique identifier.
You can also disable filtering in the router settings. Do this if you couldn't find your device's Personal ID.
You can disable filtering in the “Network” tab in the main settings of the router.
Typically, disabling filtering solves the problem.
To start using the Internet, restart your tablet and router.
On the tablet, enter the access password again; the connection process after deleting the Mac address settings may take several minutes.
Setting up channels
If even after disabling filtering you are unable to establish a connection to the Internet, check the channels.
A mismatch between the channels used can also cause problems when connecting to the Internet from a tablet.
Go back to the window initial settings router. Find the line called “Chanel” and change its value.
Try to try all the values: select one of the channel modes, save the settings. Restart your tablet and router.
Try connecting again. Do this until you try all the available channel setup modes that are presented in the router management window.
Automatic mode allows the router to automatically determine the most suitable channel for establishing communication with the subscriber device.
If the network still does not work, try doing a hard reset of your tablet - that is, returning to factory settings.
There may be a problem with the software of your Android device. You can reset the settings in the tablet settings menu.
The connection mode is set incorrectly
If all previous methods settings did not help you solve the problem with connecting your tablet and router, you should try the last one possible ways solution to the problem, which will most likely return your device to the ability to connect to the router.
Perhaps the tablet and router are operating different versions wireless communication.
The tablet may simply not see or not support the version of communication used by the router, so it does not connect to the Internet.
There are several connection mode options: 802.11n, 802.11b, 802.11g. Go to the router settings and check the connection mode option used.
Change it to anything else. Reboot all devices and try connecting again.
Thus, test the performance of all available versions of the channels.
It is necessary to carry out all the actions proposed in the article one by one, since all problems are a consequence of each other.
All the instructions described in the article will help you solve the connection problem and improve the quality of your Internet connection.
