The tablet does not connect to wifi kept secure. Why can't my tablet connect to wi-fi? Error fix options

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 gives a series of errors when connecting. In this article, we will look at the most common problems that arise when accessing the Internet and how to solve them.

Why won'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 the Android device has never connected to it. Enter a new password and check if the device connects to the Internet.

2. Viruses

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

3. Failure in the power grid

Inexpensive routers are characterized by unstable operation. Power surges can cause the tablet not to see 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 type of encryption

To check the type of encryption, go to the router settings. To do this, enter the IP address of the router in the address bar of your browser. This data can be found on the label of the device or in the instructions. In the tab that opens, select the "Advanced settings" item. Then, in the Wi-Fi section, click Security Settings. To see the encryption type, go to the "Network Authentication" menu. Choose WPA-PSK\WPA2-PSK2 mixed from the suggested options. Reboot your router. 5. Wrong time and date settings

In some cases, the tablet won't connect to the wireless network because the date and time are incorrect. After correcting these parameters to the correct ones, network operation will resume.

6. Checking the MAC filter mode

Another reason why the user on the tablet does not see Wi-Fi may be changes in the 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 for 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 banned MAC address, it closes access to Wi-Fi for this device.
If the "Allow" or "Deny" modes are selected in the router settings, check if the MAC address of your device is allowed to access 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 channels match. This problem occurs when the signals of two routers operating on the same channel intersect. Interference occurs that blocks access to the wireless network.

Look on your tablet to see if there are other wireless networks nearby. If your neighbors have Wi-Fi, then your routers may be operating on the same frequency.

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

Reboot your router.
If the channel is set in the “Auto” mode in the settings, then 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. Change WiFi 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 line "Wireless Mode" put down the item 802.11b\g\mixed. In this mode, the router provides Internet access for all types of devices.

Technology does 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 will look at why this can happen and how to fix such problems.

Some general information

To begin with, you need to understand that wifi technology has different standards and protocols. That is, today there are many different versions WiFi. However, only three standards are used in everyday life:

802.11b is the oldest standard that operates at 2.4 GHz and has a maximum throughput up to 11 Mbps.
802.11g is a standard that was approved in 2003. Allows you to achieve data transfer rates up to 54 Mbps. Operates at a frequency of 2.4 GHz.
802.11n is the most fast option wireless connection, which allows you to achieve speeds 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 the frequency difference. That is, if the router only operates at a frequency of 5 GHz, and the tablet only supports 802.11b or g (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 when buying a tablet, specify its technical characteristics.

It should be noted that many modern routers can work in mixed mode. That is, in wifi 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

Do not forget that different tablets, like routers, have different antennas. The access point may have a weak antenna, due to which it can cover a rather small area. At the same time, some tablets, due to their design features, may have a weak antenna, which is muted metal case resulting in very poor reception.

If, for example, a laptop antenna 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 even closed 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 can detect this access point. If it detects, then the problem is in 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 protect your home network, the owners hide the hotspot. Therefore, first of all, you should go to the router settings and check if the wireless mode is enabled and if 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”), then the router will not distribute the network at all. If you uncheck the second line ("Enable SSID broadcast"), then 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 in manual mode.

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

Solving problems on the side of the router

We have already discussed the basic settings of the Wi-Fi router above. That is, you check which Wi-Fi mode the router uses, and also 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, restart the access point. Just unplug the router from the outlet for 7-10 minutes, then plug it back in.

If after that the tablet still does not see the Wi-Fi network, then you should reset the router to factory settings. If this does not help, then 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. Even if the software update does not help, you will have to buy a new router. When choosing, pay attention to which modes and wifi standards supports hotspot.

Tablet side problem

If you have determined that the problem lies precisely in the tablet, that is, it does not see any network at all and does not go online even in close proximity to access points, then there are several options.

The first thing to do is simply reboot your device. The fact is that due to the accumulated cache (garbage), the tablet may not turn on at all wireless adapter, because of which the search for networks does not even start. That is, the tablet does not catch Wi-Fi. A reboot flushes the cache and repairs minor system crashes.

If this does not help, then you should move on to more drastic measures. It should be said 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 network adapter. Connecting to networks occurs automatically. Therefore, if none of the above helps, then you will have to do a factory reset.

Another reason why Wi-Fi does not catch on the tablet may be that the antenna terminal has moved away 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 master could simply forget to connect the antenna. In this case, you need to disassemble the gadget: check if the antenna is connected and clean the contacts.

Of course, such reasons are extremely rare, but still they should be considered. Also, do not forget that sometimes, due to intensive work, the network adapter can simply burn out. You will not 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 to fix the problem, it's time to bring your gadget in for repair.

V modern world mobile technologies are increasingly being used. Tablets with a variety of operating platforms are a huge success among users from all over the world. With the help of these devices, you can solve various tasks and, among other things, they are very convenient and transportable. However, despite the fact that tablets are extremely in demand, many of their users, especially beginners, cannot figure out how to properly connect Wi-Fi on a tablet in order to enjoy good and high-speed Internet.

Currently, no one is surprised by the Wi-Fi network, and a module is installed in all modern devices. wireless connection. Wi-Fi can be found everywhere: at home, at work, in places of recreation, at stations, subways and many other places. The hotspot is very easy to find.

Setting up Wi-Fi on a tablet

To connect the tablet via Wi-Fi to the Internet, you need to perform a list of simple operations:

First you need to enable Wi-Fi on the device - this can be done if there is a special widget that will be placed on the gadget's desktop (sometimes you can open widgets by swiping down on the main screen). You can also activate the module in the settings: just click on "On".
After the wireless connection is activated, a list of available connections will appear on the gadget's screen.
Click on the appropriate network.
If it has a password, then you need to enter it.

If all actions are performed correctly and the password is entered correctly, the device will be connected to Wi-Fi.

Connecting your tablet to your home network

Before using the home point Wi-Fi access, you need to activate and configure it through the router:

Enter the following numbers in any Internet browser on your PC: 192.168.1.*. (The IP address of your router is indicated on the router itself or on the box)
After that, a window will appear where you need to specify the logs and the key to open access to the router.
If the password is unknown, then on the Internet you can find out the standard login / password for any router model.

All further operations to set up the router will depend on which specific device is used to distribute the Internet via Wi-Fi.

You need to go to the router settings and find the WLAN section (maybe Wireless Lan).
Here you need to check the box next to Active Wireless LAN or to activate (set the value as Enable).
Determine what type of protection the network will have (best is WPA2-PSK).
In the SSID column, you need to enter the name of the wireless access point.
Specify the key below and confirm it if necessary.
Save settings.

After the router has been set up, all that remains is to connect to a new wireless network.

Quite often, tablet owners face the following difficulty: the tablet does not connect to Wi-Fi - the connection to the network continues indefinitely. Decide this problem possible through the following:

The Wi-Fi network needs to be renamed (preferably in English letters). As practice shows, some gadgets do not want to connect to wireless networks, in the name of which there is at least one Russian letter.
The problem may be with the router. Restart it.
The DHCP server may need to be enabled. To do this, go back to the router settings (DHCP Setup) and check the box next to Enable.
The gadget may not work with a certain type wifi encryption networks. To change the type of protection, you need to go to the security settings and try to enter some value. In order for the new parameters to be active, you need to restart the router.
Another way is to enter the IP address and DNS servers manually. To do this, open the connection settings on the device. They are located in a special window that appears when connecting to a Wi-Fi network. You should open the user's IP settings, and enter your address in the following form: 192.168.1.***. It is also necessary to fill in the "Gateway" and "DNS" fields with data, which you need to get from your Internet provider.

Connecting to a Wi-Fi network in public places

Wi-Fi is characterized by faster and better data transfer compared to cellular network. The use of a wireless network provides the opportunity to achieve significant savings (if there is no unlimited tariff plan). In addition, many tablets do not have 3G capability, so connecting to Wi-Fi in public areas is a must. Most networks are secure, so you'll need a password to connect.

How to connect a Wi-Fi tablet to a wireless network

The first step is to open the device configuration and go to the wireless connections section.
You need to make sure that the Wi-Fi function on the tablet is activated. This means that the tablet device will search for available networks in active mode. If such a point is found, it will be shown here, indicating whether the network is password protected or has public access.
You need to touch the name of the network to which you want to connect.

In the tablet settings, you can activate a function that will periodically notify the user about the presence available networks in the current area. To connect to the network, you need to touch this notification. If you need to deactivate the notification function, you can open the settings tablet device, the "Wi-Fi" section, and uncheck the box next to "Notify me when new networks are detected."

If there is exact information that there should be wireless networks in the current area, but for some reason they are not displayed on the device, then you need to turn it off and then activate it again Wi-Fi function. To connect to a secure network with a password, you need to know the access key. Just enter it in the appropriate field and touch the "Done" icon. To disconnect from a network, you must touch and hold its name, and then select the "Delete" command.

Some points may be hidden and not displayed on the device. In this case, even if the function of notification of available networks is active, the access point will not be displayed. To connect to such a connection, you need to select the "Add" function in the Wi-Fi settings, and then specify the network name and password.

When entering the network name and passkey, be aware that they are case sensitive. You must enter this data very carefully, since the slightest mistake will prevent access to the wireless connection. The function of adding and connecting to an invisible network may not work on some gadgets. This is due to the lack of required software, which must be preinstalled by the gadget manufacturer.

How to activate Wi-Fi without a router, even if there are no others wireless networks? In such a situation, you can resort to the help of others. mobile device, for example, a smartphone. It is necessary to make it so that it becomes an access point and distributes Wi-Fi itself. The required function is present in many devices as standard parameter. If not, then you can install third party application, of which there are many.

Summarize

In most cases, connecting to Wi-Fi on a tablet does not cause any difficulties. It is enough to use the standard functions of the tablet device. If you still have any difficulties with how to connect Wi-Fi on your tablet, it is recommended that you carefully read the above instructions and tips. Wireless Internet connection is much more convenient and cost-effective compared to mobile networks. You can comfortably download movies, play online games, listen to music and watch videos online.

Wi-Fi wireless technology has long gained wide popularity, so almost every smartphone or tablet can connect to such a network. This is very convenient, because you just need to find the desired access point, enter the password and use the Internet. This article will discuss what to do if the Lenovo tablet does not connect to Wi-Fi.

Description of the problem

When connected Android devices To WiFi networks the message "Saved, WPA/WPA2 secured" usually appears. In some cases, even with this notification, there is no Internet on the tablet and you need to somehow solve the problem. We will talk about this below.

Why is Wi-Fi not working?

If you can't open web pages in your browser after connecting your tablet to a hotspot, you'll need to take a few steps to try to fix the problem. The problem can be both in the wrong settings, and in the router itself.

Solutions

Below are the main methods that should help solve the problem. Let's get straight to the point.

If the Lenovo tablet or phone successfully connects to Wi-Fi and a notification appears on the screen, you can try restarting the router. Sometimes after that the pages in the browser start to open, which means everything works correctly.

Wrong password

Everything is simple here. If the message “Wrong password”, etc. appears when connecting to the access point, then the entered combination is not correct. If the password is correct, then you need to use one of the solutions described below.

An error in Wi-Fi 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 router settings, then read the instructions (it is usually located in the router's packaging box).

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 desired country in the "Region" item. Do not forget to confirm saving the new settings using the special 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 in the speed of sending data. B is the slowest mode, g is the average, n is the fastest mode.

Changing the mode of operation can solve the problem with Wi-Fi. After changing the settings, you need to restart the router and Wi-Fi on the tablet.

The 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 incorrect wifi work. You may need to change the mode of operation or the channel of the router.
