The question "why the tablet does not connect to wifi" sooner or later "baffles" almost every active user of android devices. At the same time, there are no obvious "symptoms of the problem": the router worked and still works, the tablet itself looks quite "viable", the Internet is paid for and on the stationary computer it happens normally, only the tablet does not connect to the Internet via wifi.
And in this article we will look at why such a problem occurs, and what the user should do if the tablet does not see wifi.
Why the tablet won't connect to wifi: the main reasons
So, the most common reason that the tablet does not connect to Wi-Fi is - in other words, incorrectly entered.
To eliminate the error, you need to carefully check the correctness of entering the security key: language, case, "layout" of the virtual keyboard, etc. As a last resort, you can delete it again.
Other “popular” reasons why the tablet does not see wifi include:
- 1. Mismatch of encryption types
- 2. Restricting access to the network by the device's MAC address
- 3. Limiting the number of active connections on the network
- 4. Malfunctions of the router
The tablet does not connect to Wi-Fi: what to do?
After checking the connection parameters, there is no need to make any additional settings on the tablet itself - further "diagnostics" is carried out through the web interface of the router.
It is more convenient to set up a network connection through a stationary computer.
So, if the Lenovo tablet does not connect to wifi, you need it. To do this, enter the personal IP address of the router in the search box of the Internet browser and press "Enter".
As a rule, the IP address of the router is indicated on the service label of the device - in most cases it is a combination of 192.168.1.1. or 192.168.0.1
Here you need to check the following parameters:
1. The type of encryption.
Most tablets support 2 types of encryption: WPA and WPA2 personal. If you change the type of data encryption in the router settings, the tablet will not be able to pass verification and connect to the router.
The type of encryption is specified in the security settings of the WiFi network - this is the "wireless network" or WLAN tab.
2. Network access right for MAC address and number of active connections on the wireless network.
This characteristic can be found in the DHCP settings section, which shows which devices are currently connected to your router.
Also in this column are marked all MAC addresses of the connected devices. If opposite the MAC address of your tablet there is a check mark in the "block" item, then this means that you will not be able to connect to the network.
In order for the tablet to seamlessly connect to the Wi-Fi, you need to uncheck the box and save the changes.
Also here you can see if there is a limit on the number of active users of your WiFi network. So, if the maximum allowable number of active connections is set to two, then when you connect a laptop and a cell phone to the network, you should not be surprised that the tablet does not see Wi-Fi - there is simply no "free space" left for it.
The number of active wifi users can also be determined using, and the best protection against virtual thieves will be a strong and unique password.
In addition, when solving the global question "why the tablet does not connect to wifi", do not forget about the standard measures of "curing" electronics: restart the router using the ON / OFF button and reconnect to the network through the "search for available devices".
The tablet computer is an incredibly handy invention. With it, you can not be tied to the workplace, as is the case with stationary computing systems, and also not carry extra pounds with you 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 understandable that if the tablet does not see WiFi, then such a problem should be resolved immediately.
Connection procedure
The number of tablet computers running the Android operating system is ten times more than their counterparts running the corresponding version of Windows or iOS. That is why this article will focus on mass devices. People who first encounter Android-based devices may not always be able to use wireless communication correctly. And since in the normal state the Wi-Fi module is turned off, beginners have a question: "Why does the tablet not connect to WiFi?" In fact, everything is quite simple. The process of joining an existing wireless network includes several mandatory steps:
- activation of the transceiver module of the tablet computer;
- scanning the range and selecting the desired SSID from the list;
- a set of a secret combination.
If the network to which you are connecting is open (Free), then the last item is not required.
How to connect a tablet via WiFi
You need to open the "Application Menu", which is available on any Android device. Usually, to access it, you need to click on the circle image 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 section "Wireless networks".
If you select the WLAN item, you can see the "Off / On" switch. When enabled, it will automatically scan frequencies and display a list of detected networks. You can also see if and where password access is being used. 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, you will be prompted for a password. By specifying it and pressing the corresponding button, you can connect the mobile device to the network.
There is a faster way to access Wi-Fi. There is no need to search for "Settings" for this. It is enough to slide your finger down the screen, pulling the shutter, find the WLAN (Wi-Fi) image and click on it. The module will be activated, scanned and given a list of networks.
Nuances of an alternative method
Nowadays, many owners of Android devices often replace the official firmware with a custom one (made by craftsmen). As a result, not all functions work as usual. For example, if you use a shutter call, then often the tablet 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 the "Settings". When using, keep in mind that some of them have acknowledged networking errors. At the same time, the latest "self-written" software updates often integrate the most recent versions of Wi-Fi drivers. The takeaway is simple: before reading a ton of information about why the tablet won't connect to WiFi, sometimes it's enough to change the firmware.
The problem of standards
In order for devices to be able to integrate into a wireless network, the protocols they support must be compatible with each other. So, 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 "clumsy" configured access point can ruin the life of the most patient owner of a modern tablet.
Intermediate solution
So why won't the tablet connect to WiFi? There are many reasons. We have indicated the most simple ones above. In addition, the ability of the tablet 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 is due to the fact that, although the device “sees” the router, the data packets being sent do not reach the addressee. The solution is simple - physically move closer to the access point. This "disease" often suffers from inexpensive ones in which cheap transmitters are used.
Crutch program
But what if, for no apparent reason, the tablet stopped connecting to WiFi, although until recently everything worked fine? You can try to use a wonderful software solution handed out for free in the Market - Wi-Fi Fixer. After installing the application, the tablet needs to be rebooted, and the subsequent connection to the network is performed through the interface of this program, which will be displayed in the shutter. In addition, sometimes it helps to solve transmission speed problems.
Working with settings
Understanding why the tablet does not connect to WiFi, one cannot fail to mention possible failures in the operating system itself. Installing third-party applications, making changes to the operation of components, obtaining root rights - all these can affect Wi-Fi. You can try to restore efficiency by returning to factory settings. To do this, go to "Settings - Personal data" and use "Restore and reset". In this case, all user data (including the phone book not flushed to a file) will be erased. Therefore, you must first prepare copies.
Wi-Fi wireless technology has gained wide popularity for a long time, so almost every smartphone or tablet can connect to such a network. This is very convenient, since you just need to find the desired access point, enter the password and use the Internet. This article will discuss what to do if Lenovo tablet does not connect to Wi-Fi.
Description of the problem
When connecting an Android device to a Wi-Fi network, the message “Saved, WPA / WPA2 Security” usually appears. In some cases, even with this notification, there is no Internet connection on the tablet and it is necessary to somehow solve the problem. We will talk about this below.
Why isn't Wi-Fi working?
If your browser does not open web pages after you connect your tablet to the hotspot, there are several steps to take to try and fix the problem. The problem can be either in the wrong settings or in the router itself.
Solutions
Below are the main methods that should help solve the problem. Let's get straight to the point.
If a Lenovo tablet or phone successfully connects to Wi-Fi and a corresponding notification appears on the screen, then you can try to restart the router. Sometimes after that, pages in the browser start to open, which means everything works correctly.
Wrong password
Everything is simple here. If, when connecting to an access point, the message "Wrong password" appears, etc., then the entered combination is not correct. If the password is entered correctly, then you need to use one of the solutions described below.
An error in Wi-Fi operation often occurs due to the wrong region in the settings. To change the region, you need to go to the device web interface. If you do not know how to open the settings of the router, then read the instructions (it is usually located in the packing box of the router).
Let's consider the process of changing the region using the example of a router from the manufacturer TP-Link. You need to open the "Wireless mode" tab and select the required country in the "Region" item. Do not forget to confirm the saving of the new settings with the dedicated button.
Wi-Fi network operation mode
The router may operate in a mode that is not supported on Lenovo gadgets. There are 3 modes in total: b / g / n. The main difference is the speed of sending data. B is the slowest mode, g is the medium, n is the fastest mode.
Changing the operating mode can solve the wi-fi problem. After changing the settings, you need to restart the router and Wi-Fi on the tablet.
Tablet does not see Wi-Fi
It may well be that the router is turned on and working properly, but the phone or tablet does not see the access point. In this case, you need to check the settings - this is one of the main reasons for the incorrect operation of Wi-Fi. You may need to change the operating mode or channel of the router.
Outcome
This article describes the most effective ways to solve the problem of not working Wi-Fi on Lenovo devices. If you know others - write in the comments.
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 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 installed in the gadget and then connect to the selected access point by writing a password.
However, sometimes wifi, that is, access 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 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 a WiFi wireless network. Sometimes WiFi does not turn on in a tablet computer, both due to the presence of problems in the device itself, and due to malfunctions of network equipment.
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 owner of the tablet himself is the culprit 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 a Wi-Fi network security, for example, using Wpa2 protection. It is recommended to set a check mark on the line “Show password” when dialing the access code. In most cases, this ensures that the password is spelled correctly.
In the case of absolute certainty of the exact set of the password, and at the same time the Internet cannot turn on, you first need to check the operation of the router. Difficulties often appear due to incorrect settings of the router, its overload, power surges, etc.
Restarting the router
If the tablet or smartphone from Lenovo or another brand does not connect to the wireless WiFi network, a message about this is immediately displayed on the display. A restart of the router to which the user intends to connect is required. In most cases, after this procedure, the Internet begins to function normally in the device. 
Analysis of the operation of the security system of a protected Wi-Fi network
When the gadget cannot establish a connection with the router and at the same time writes is saved in the status bar, then we can conclude about the various types of encoding used by the router and device.
You must perform the following sequential steps:
MAC address settings
Most often, errors in filtering MAC addresses appear when Lenovo and Asus tablets are working with cheap router models. In order to ensure maximum security, these gadgets determine the MAC address, and in the case when it is not determined, then the access to the global network is blocked, which is often a problem, why access to the network in the tablet is not turned on.
The following steps must be taken:
If it was not possible to successfully solve the problem, then you should try to temporarily disable 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 tune the channels.
This requires the following steps:
- Enter the router settings;
- Change the value in the "Chanel" item (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 are unsuccessful, you will have to resort to resetting the tablet PC settings. 
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 version of the 802.11n connection, as well as with the "b" and "g" prefix.
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.
Not only does the tablet fail to connect to WiFi when network problems occur. Perhaps the problem lies in the tablet itself.
Let's consider how to solve the resulting breakdown.
Android tablet users often encounter non-working WiFi. You can solve almost all the causes of the problem yourself.
Incorrect password entered
One of the most common mistakes the user is to blame is entering the wrong password.
If you do not know why you cannot access the Internet via WiFi, when entering the password, click on the "show password" checkbox to make sure that all letters and numbers are entered correctly.
If you enter the access code correctly, you should consider the following possible causes of breakdown, which are presented below.
You do not need to make any adjustments with the tablet itself, this can only aggravate the situation.
All actions will be carried out exclusively with a router.
Problems with the operation of the router can occur due to its incorrect configuration, when too many subscribers are simultaneously connected and using the device, power outages and other problems.
Unplug the router from the network for a few minutes and then plug it back in, this method can also solve the problem with the connection.
Checking the used encryption algorithm
If your tablet does not connect to the router, and the status bar says saved, the cause of the problem is the different types of encryption that the tablet and router use.
If a newer encryption mode is selected on the tablet than on the tablet, the user will not be able to authenticate, thereby accessing the Internet will be impossible.
This problem is common on Samsung and Lenovo tablets.
Follow the instructions to configure the same encryption types and resolve the issue:
- Enter the router settings. To do this, you need to connect to it using your personal computer or laptop;
- Open your browser;
- Enter the address of the router 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 did 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 see the exact 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 on the 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 username and password from the browser admin panel. You can view the login information in the instructions for the device (router);
- On the quick settings tab, check the type of encryption used by the router. 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, the devices will be authenticated normally, and you will find that the tablet sees the network and connects to it.
MAC filter
Incorrect filtering of the 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 in the process of their interaction with inexpensive budget versions of routers.
To increase the level of protection of the connection, it is necessary 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 will block access to the Internet.
This may be the reason the tablet stopped connecting and the error appeared.
To correct the MAC address settings, follow the instructions:
- Go to the router settings. How to do this is described in detail in the previous instructions of the article;
- Go to the "Network" tab. The names of the tabs may differ depending on the model of the router you are using. In the "Network" tab, make sure that the MAC addresses of the device and the computer are identical;
- Press the save key, restart the router and the device;
- Connect to the router again. Everything should work stably.
Important! You can find out the physical address of a custom 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 configuration. Do this if you could not find the personal identifier for your device.
You can disable filtering in the "Network" tab in the basic settings of the router.
Usually, disabling filtering will fix 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.
Channel setup
If you still cannot connect to the Internet even after disabling filtering, check the channels.
A mismatch in the channels used can also cause problems when connecting to the Internet from your tablet.
Return to the initial router settings window. Find the line called “Chanel” and change its value.
Try to try all values: select one of the channel modes, save the settings. Reboot your tablet and router.
Try to connect again. Do this until you have tried all the available channel tuning modes that are presented in the router control 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 hard resetting your tablet - that is, returning to factory settings.
There may be a problem with the software of the Android device. You can reset the settings in the tablet settings menu.
