Lenovo tablet does not turn on Wi-Fi. The tablet does not connect to the Internet via wifi. Setup Tips

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 enter the access code correctly, you should consider the following possible causes of failure, 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 can 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 a newer encryption mode is selected on the tablet than on the tablet, the user will not be able to authenticate, 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 on your 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);

• In the quick settings tab, 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.

Return to the router's initial settings window. 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 the previous setup methods did not help you solve the problem with connecting your tablet and router, you should try the last possible solution to the problem, which will most likely return your device to the ability to connect to the router.

It's possible that your tablet and router are using different wireless versions.

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.

What to do if Wi-Fi is connected but the Internet does not work on Android

What to do if the tablet does not connect to WiFi - Instructions with examples

Hello! Yes, I will write again about problems with Wi-Fi :). Someone needs to fight capricious wireless networks, which usually provide more inconvenience during setup than pleasure during use. Very, very many different problems arise, and most of them are difficult to even explain.

Today I will write about one of these problems. And I will give some recommendations that may help you solve it. But I can’t guarantee anything, I hope you understand.

What does the problem look like?

I think that after reading the title of this article, you can already understand what this article is about. I began to notice comments in which people wrote that their devices, be it a laptop, a computer with an adapter, a phone, a tablet, or a game console, did not see their home Wi-Fi network. It is simply not in the list of networks available for connection. At the same time, the device sees neighboring networks. But why? I thought for a long time, but could not come up with a logical explanation for this problem.

By the way, such nonsense can occur even after some work with Wi-Fi, that is, everything was working, you turned off the laptop (for example), and turned it on, but it no longer sees your network.

Here you need to act quickly and save your phone or other equipment from flying into a wall or window :)

Attention! This article is about when a device does not see a wireless network, but only one network, for example, while other neighboring networks are detected.

The device does not see Wi-Fi [possible solution]

Roman left the following comment on the site:

To be honest, I didn't know what to recommend. But then I thought again and realized that, as a rule, the most incomprehensible problems arise due to the channel on which the wireless network operates, or rather due to interference on the channel.

And I advised you to experiment with channels, as written in the article. Roman changed channel (unfortunately, he didn’t write which one he installed, but it doesn’t matter, you need to experiment) and everything worked for him. The laptop saw the network. A free channel can be determined using the InSSIDer program.

I don’t know if changing the channel really helped, or just rebooting the router 🙂 but the problem was solved. By the way, Reboot the router first if any problems arise. A simple reboot often helps.

There was also a comment where the game console stopped seeing the home wireless network. But I don’t know how it all ended.

You can also try experimenting with the mode of operation of the router, I wrote about this in the article.

Perhaps you have already encountered this problem and somehow solved it differently, or please leave your thoughts on this issue in the comments. And I will update the article and add useful material.

Bye everyone!

The laptop (phone, tablet) does not see the home Wi-Fi network (it sees the neighboring ones) updated: February 7, 2018 by: admin

Hi all! As I already said, I work as a sys. I am an administrator at an Internet cafe, and naturally I understand computer equipment and local networks.

So, recently my Aunt called me and asked me to come set up the D-link wi-fi router that she had just bought in the store. I arrive, set it up, everything is fine. Aunt is happy. Surf the Internet on a netbook via Wi-Fi

But it was not there! The next day he calls and says the phone doesn’t see wi-fi and the laptop doesn’t see wi-fi! It only finds some neighbors’ access points and that’s it, well, I come, I think, let me check the router at home, I take it home and connect it. Everything is ok, everything works! I'm shocked =) I come back to Auntie and connect it again, it doesn't work... So I went to a friend and it worked for him too... Then I started rummaging through the settings of the router, but I couldn't find anything.

Then my Uncle comes into the room and says there is a security company downstairs, maybe their equipment is blocking them? I think for sure! The problem is there, you won’t see Wi-Fi Aunt And I’m leaving...

But a few days later, 1 more person called me with the same problem! And after a long time I found a solution to this problem! In this article, I will now explain everything step by step how to solve this problem!

Nowadays, a Wi-Fi router has appeared in almost every apartment, and when you turn on the router in a neighboring apartment, your Wi-Fi Internet may disappear (everything will work fine through the cord in the computer).

Solution

I’ll show you the example of a wi-fi router D-link DIR 300

The problem was that when setting up the router, the Wireles channel is selected by default automatically (auto), shown in the screenshot:

We need to go to the router (web interface), if you did not change the local IP address when setting up the router, then it remains the default 192.168.0.1 , write this IP in the browser and go to the router’s Web interface.

We go to the item as in the screenshot and change the channel, set a number different from the one set automatically (I always got it the first time and everything started working).

It is impossible to remember a tablet from the 2010s that did not have a Wi-Fi module. Fast wireless Internet is a must-have feature for portable smart devices. It’s all the more offensive when it doesn’t fulfill its task and doesn’t provide access to the Internet.

We do not consider the case where the device does not turn on Wi-Fi at all. Here there can be only one recommendation: quickly take the tablet to a service center. Another unpleasant option is more common: the device seems to find the desired Wi-Fi, but cannot connect to the Internet.

Let's try to describe the most common problems with Wi-Fi connections and ways to solve them. Some of them will only require changing the settings of your tablet or router. Others will force you to spend a certain amount, but incomparably less than on repairing a tablet (or even more so buying a new one).

Why might Wi-Fi not perform its function?

How to solve: go into the router settings and change the Wi-Fi channel (for example, instead of automatic selection, assign a static 6th channel). Choosing a different network mode also helps: instead of 11bg mixed, put 11n or 11g. This method is applicable when you have problems with your own router and you have full access to it.

Bad signal. Formally, there is a Wi-Fi connection, but it is not possible to connect to the Internet through it. Reason: interference, especially if the router is behind a wall or several.

How to solve: bring the tablet close to the router and check the connection. If everything works without any obstacles, you are better off moving the router or using a signal repeater. Today, repeaters are inexpensive enough to install in one or more problem rooms.

Technologies do not stand still. Mobile devices, with which you can easily and quickly access the Internet, are an integral part of every modern person. 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. However, 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 the wireless mode is turned on 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.
