This article will tell you why WiFi does not turn on or connect on your Android tablet or phone, although the device sees a wireless network

This article is suitable for phones and tablets of all manufacturers of Android devices: Samsung, LG, Sony, Huawei, Xiaomi, HTC, ZTE, Fly, Alcatel and others. We are not responsible for your actions.

Wi-Fi module in a smartphone or tablet on the Android system is one of the most important this moment components. We are surrounded by wireless networks at home, at work, in public transport and favorite coffee shops.

In the Android system, Wi-Fi may stop working at the most inopportune time. Let's look at the reasons for this:

The Wi-Fi module itself is out of order.
Installing the wrong firmware.
Operating system failure.
The system or network connection settings have gone wrong.
Password entered incorrectly.

The problem most often lies in the settings. Of course, when a smartphone falls into water, there is a possibility that something has happened to the module. If there were no mechanical effects, and Wi-Fi disappeared suddenly, then the error most likely has a software cause.

When Wi-Fi does not start on Android, first of all you need to do:

Check if airplane mode is enabled.

Increase

Check your Wi-Fi router settings.
We look to see if the Wi-Fi router is working (if possible), restart it.
Reboot your tablet or smartphone.
Check if the time and date are correct.
Delete the network profile and re-enter the password on the product.

Increase

Often the reason for not working Wi-Fi is quite simple. But it does not always consist in the downed time or in the wrong password. If after the above steps the Wi-Fi icon is still gray, you should move on to more drastic operations.

Restore settings

Incorrect date and time is not a common mistake, but still needs to be checked. Perhaps the whole problem is that the device does not show them correctly. To check, you need to open the "Settings" of the tablet / smartphone and look at the "Time and date". If the settings are incorrect, then change them.

Increase

You may have changed network passwords, but did not enter them into the gadget. Go to "Settings wireless connection", then delete old profile from which you were unable to connect to the network. Now try again to connect to Wi-Fi.

Increase

If the “airplane mode” is not active, and the time, date and password are set correctly, then you can reset the gadget to factory settings. You must first save the data to another device or cloud storage.

Android users are still facing the issue eternal loading when they try to update or install applications through the Play Market. This also affects the performance of the network. To resolve the issue, you need to delete temporary files and clear the cache of the Play Market.

Router settings

If the router parameters are set incorrectly, this may lead to the inoperability of the Wi-Fi network. For correct setting router, you must complete all the settings that are indicated in its instructions. Take the box from under the router and find the documentation to set everything up correctly.

For example, open the "Device Management Menu", select the "Uninterrupted Mode Settings" item. Now you should change the parameters in two lines. We set the parameter "auto" to "Channel", and for "Mode" we specify the value "11 bgn mixed". Go to the "MAC Address Filtering" menu and change the value to "disabled".

Increase

Android engineering menu settings

If the gadget runs on a MediaTek processor (this is not possible for most devices with Qualcomm processor), you can go to engineering menu and set the Wi-Fi settings directly through it. The menu is opened by entering the combination "*#*#3646633#*#*" in the dial pad.

If the tablet does not have such a panel, you can use special utilities to enter engineering mode. Thus, the settings are checked and set in the "connection" section.

Through the engineering mode, you need to configure something only in a situation where you are an advanced user of the Android platform. This mode is intended for developers, and any changes at random can disable the gadget.

Setting up Wi-Fi on an Android TV box

The TV-box works on Android, just like tablets with smartphones. It may also have connection problems. Here it is recommended to use an external Wi-Fi adapter or connect a cable, but this will only affect the speed improvement.

If not at all WiFi connections, then we execute the algorithm:

Let's go to the file manager.
We find the WIFI folder, in it we define the wpa_supplicant.conf file.
We delete the file.
We wait for some time, we launch a search on the Wi-Fi set-top box.
The product will find the connection automatically.

Software failures

This is another common reason for Wi-Fi not turning on. Unstable work software can be identified simply: download to the device and install the software.

Suitable for this wifi utility Fixer. This small application is designed specifically to resolve issues with unstable Internet on the Android system. Neither your content nor your settings will be affected.

Increase

After launching the application, the main window will open, which shows the status of the Internet connection. The item "Known" contains important information about all connections.

Increase

All the user needs to do is restart the gadget and reconnect via Wi-Fi.

Also, Wi-Fi may not work due to recently downloaded applications. You need to go to the application manager on the device and see which application during the flight has the most activity.

This application should mercilessly consume battery power, so the tablet or smartphone is discharged faster. It will be enough to uninstall the application or install a different version with which the error was not observed.

It is also recommended to check if applications are installed on the product that restrict Internet access. Through a number of firewalls, you can set restrictions even without having root rights. Additionally, it is recommended to check the gadget for viruses. Some malware With network connection over Wi-Fi can cause problems.

Installing the wrong firmware

Custom firmware can cause problems with the functioning of the Wi-Fi module. It may block the connection. Manufacturers are advised to work only with official firmware versions, as custom versions are not always reliable. If there are problems after flashing, then you need to roll back the device to the factory settings or flash it again, only to the official one.

Wi-Fi technology is very widely used in the life of a modern person, because it allows you to easily and quickly solve the problem of connecting to the Internet without using conventional wires. This is especially true in the case of using laptops, with the help of which you can access the Internet in any convenient place due to the presence of a built-in Wi-Fi adapter.

That is why the situation when Wi Fi does not work on a laptop leads to significant inconvenience and even some problems. The reasons why on laptop computer may not work Wi-Fi, there are quite a few. It is simply unrealistic to solve the most serious of them on your own without the help of specialists, but there are quite a lot of those that can be completely eliminated on your own. Let's consider them.

Problem with laptop or router?

A fairly common problem is that the laptop has stopped connecting to WiFi networks, the problem is not with the laptop itself, but with the settings of the router, which distributes the network. Thus, the laptop can be configured correctly, but Wi-Fi still does not turn on precisely because it has nothing to connect to.

To exclude the possibility that the problem is related to this, you should try to connect to the network from any other device that is equipped with WiFi adapter– from another laptop, smartphone, tablet, etc.

If Wi-Fi does not work from another gadget, then the problem lies precisely in the Wi-Fi router distributing the Internet. If the connection is successful, the problem is in the laptop and before solving it, you first need to determine why Wi-Fi stopped working.

Hardware enable adapter

Based on this diagnosis, it can be precisely determined that this problem arose precisely because of the laptop. When Wi-Fi does not work on it, you can try using several methods.

The first one is to check if the adapter is enabled wireless connection on a laptop. Almost all modern models have light indicators of the WiFi module and there are special key combinations for its hardware activation.

Usually, a lit indicator indicates that the module is on. If the indicator does not glow at all or shines in red, then the Wi-Fi does not work precisely because of the adapter wireless network. It needs to be enabled.

Most often, such indicators are located directly on the keyboard, side or front panel of the device. Sometimes they are located on the monitor case or near the touchpad.

To enable the module of such a network, press the key combination Fn and one of the system F1-F12. The specific combination depends on the laptop manufacturer. Usually, the corresponding antenna icon is located on the desired key. If it is not there, then to enable Wi-Fi, you should try to press the standard button for specific model combination:
Fn+F3 for Acer;
Fn+F2 for Asus, Dell or Gigabyte
Fn+F5 on Fujitsu devices;
Fn+F12 on HP laptops.

After pressing the appropriate keys, we check whether the indicator of the wireless connection module lights up or whether it stops glowing red. After that, you should try to connect to the network again. If this does not help, go to the next step.

Software inclusion

When Wi-Fi stopped working and its hardware inclusion does not give positive results, it is also necessary to implement its software inclusion, which is carried out directly from the operating system under which the laptop is running.

To implement software turn on WiFi, which stopped working, on Windows 7, 8 or 10, you need to perform the following sequence of actions:

1. On the notification panel, which is located near the clock, the network connection status icon is selected;

2. From the list that opens, select the item "Network and Control Center and public access" or " Network settings» depending on the version of the operating system;

3. The next step is "Change adapter settings".

Among the list of all existing connections pay attention to the color of the "Wireless" icon network connection". If your WiFi does not work and the wireless adapter is disabled, then the connection icon will not be highlighted. In this case, click on its icon right click mice, from the opened context menu select "Enable". In this case, the color of the connection icon should change.

At the same time, the wireless network adapter turns on, it remains to find the desired one in the list of available wireless networks and connect to it.

If, after such actions, Wi-Fi, which has stopped working, continues to be inactive, you need to move on to the next method to solve the problem.

Installing and updating the driver

Quite often, the Wi-Fi wireless connection does not turn on due to the lack of a driver or when it is very outdated. To determine the presence installed driver, it is necessary from the context menu of the "My Computer" icon, which is located on the desktop or in the "Start" menu, select the "Properties" item. Next, in the window that opens, select the "Device Manager" command from the menu on the left.

In the new window that opens with a list of connected devices, you need to find the name of the laptop's wireless network adapter. Usually its name is "Wireless network adapter” or “Wireless Network Adapter”, along with which the manufacturer of the device must be indicated: Realtek, Atheros, Qualcomm, or something else.

Having found the desired item and clicking on it with the right mouse button, "Properties" is selected from the context menu. In the window that opens in this case, the item "The device is working properly" should be present. But even if there is a mark about the normal operation of the device, this is far from a guarantee that the correct driver version is installed and Wi-Fi is turned on correctly. To check it, in the properties window wireless device go to the "Driver" tab and pay attention to the items "Date of development" and "Supplier".

In the event that the supplier is Microsoft or the date of development of the program is several years behind the current one, go to the official website of the laptop manufacturer and download the latest official version drivers.

The same should be done if among the list installed devices there was no wireless adapter.

If the module is in the list of devices wireless communication present but marked in yellow exclamation mark, this means that the device is disabled, causing the network to stop working. In this case, having opened the device properties window, you need to click the "Enable" button.

Another reason why Wi-Fi stopped working on a laptop may be that the power saving mode is enabled, which prevents the wireless connection from working. To disable it, you need to do the following:
1. Open Control Panel;
2. Select the "Power" icon;

3. In the window that opens, select the "High performance" or "Balanced" mode.

External signal obstructions

It's also worth noting that a broken wireless network can also be the result of more than just laptop problems. The wireless connection signal depends on some external factors that can weaken it. Ceilings, walls, floors, and similar obstacles significantly degrade the signal quality of the access point and laptop.

As you know, signal quality personal computer displayed as several marks - the more there are, the better the signal is. If the wireless connection level is displayed as 1 or 2 marks, then you can not try to use WiFi - in this case, it will not work properly.

In this case, you need to move the router closer to your workplace, move your workplace closer to WiFi router Or buy a new, more powerful router.

If nothing helped

If none of the tips above helped, you can use a simple, but at the same time often effective solution: restart both the computer and the wireless router. Please note that after a reboot, the router turns on for up to 5-10 minutes before it starts distributing the network. Be patient. Also, despite the opinion of many skeptics, sometimes the troubleshooting function that is in operating system Windows.

Thus, most of the above existing solutions problems related to the fact that Wi-Fi stopped working on a laptop. Almost all of these methods and recommendations can be used by anyone who has encountered a similar problem, since this does not require any special skills.
If nothing helps, and the wireless network does not start working, there is only one way out - to go for help to a quality service center where they can solve any problems with the laptop.

Wifi internet not working on android. Solution

1. Initially try connecting and disconnecting the wireless network on a computer or phone. Turn airplane mode on and off. Reboot your device. In some cases this works.
2. Check your proxy settings. If your device has a proxy server checked in the wireless network settings, most likely the internet won't work.. You need to go into the settings and, if necessary, disable the proxy server. To do this, open the panel with a list of Wi-Fi networks and the network you are connecting to. Next, click on the desired network and hold it for a while. A menu will open on the screen where you need to find an item like " Network change". This will help open the proxy server setting (it should be disabled).

Then, check the box next to the category " Advanced features" and go down a little lower, to the tab " Proxy server". If the settings say " manually“, the Internet most likely will not start. Study the image carefully, there will probably be some differences in your case.

If it is deleted, download it again, go to the program, click " Stop and then safely delete it. Many users note that because of it there are problems with the idle Internet via wi-fi. After these steps, the Internet can work.

5. Set get IP address to automatic mode . If the problems are IP related, then the device most often cannot even connect to Wi-Fi. To check this, go to the wireless network settings and find the characteristics of your network. Place a check next to " Advanced features” (you probably won’t need to do this), after which you will see a category like “ IP parameters» « IPv4 settings", where automatic IP acquisition should be set - DHCP.

6. Some say that loading static DNS addresses will solve the problem. This method works in situations where the Wi-Fi icon on your device has a gray tint and the Market does not open. In addition, individual resources may not start.

To do this, you need to go to the parameters of this wireless network. Place a check next to " Advanced features” (if necessary) and select the category “ IPv4 settings". Next, find the items "Manual", and DNS1, DNS2, where specify the following addresses: 8.8.8.8 and 8.8.4.4 so as in the picture:

You can change the DNS in your router settings if that makes it easier for you.

7. Also try to reset all the settings of your smartphone, provided that you have time for new installations of programs, etc. However, if other methods do not work, then the reset must be done.

Reconfiguring the router as a solution to the problem of broken Internet on a phone or tablet

Do not forget that the Internet from your router must function on other devices. If it refuses to run on other devices, you need to check the router settings, since this is not Android's fault. Generally, the following recommendations show positive results when your phone or tablet doesn't find a wireless network at all, or can't connect to one. Also, before setting up, try rebooting the router.

1. Change the channel in the router toolbar. Often, it is he who causes problems with connecting to Wi-Fi. You don’t even have to look for an available channel, because this procedure will take a lot of time, just set any static one, for example - 7. To do this, go to the “ wirelees" (on different modems, the tab will be similar), then in " Wirelees Setting"and select any in the window" Channel» and press « Save«.

2. In the same place where you can change the channel, you can most often change the region. Such settings are mainly located on the page with tools for the wireless network. Specify the required region.

3. Immediately, try resetting the Wi-Fi operating mode. Such settings are provided on any router. Experiment and try several different versions. For example, set the option n only. In this case, be sure to save all changes and reboot the router.

Some of the above tips should definitely help if you have problems with the Internet while connecting to Wi-Fi.

A lot of users, when trying to connect their Android smartphone or tablet to WiFi networks, faced with many different problems and mistakes. In this article, we will try to deal with the problem that appears after connecting an Android device to Wi-Fi. When Wi-Fi does not work on a smartphone or the same tablet. More precisely, the Internet does not work when connected via a wireless network. A very popular problem.

Connect your smartphone to home wifi network, or at work, there is a connection, but the Internet does not work. Websites won't open in browser Google Play The market does not work, other applications that need Internet access also refuse to work. True, there are exceptions when, for example, sites open in the browser, but the Play Store does not work, and YouTube videos do not play. As a rule, the Wi-Fi icon in such cases is gray and not blue, as it should be. We will also talk about this.

When many people write that Wi-Fi does not work on a smartphone, they have to enter exactly that Android connects to Wi-Fi, but does not load anything. If your mobile device does not see any Wi-Fi networks, or some errors appear when connecting, then this is a completely different topic, we will definitely talk about these problems in another article. Or, check your router if it is. Now we will consider exactly the case when an Android smartphone connects to Wi-Fi without problems, but there are problems with accessing the Internet.

In fact, there are a lot of reasons and solutions. The whole difficulty lies in the fact that the problem can appear both due to some problems in the settings of the tablet or smartphone itself, and due to the settings of the router. We will first check whether the settings on the mobile device itself are correct, and if this does not help, then we will change the settings of the router.

Android: Internet over Wi-Fi does not work. Solving a problem on a smartphone

If you have a tablet, then these tips will also work.

1 First of all, you can try turning off / on Wi-Fi on the device. Enable/disable flight mode. Restart smartphone. Sometimes it helps.

2 Checking the proxy server settings. If a proxy server is enabled on your smartphone, in the properties of your wireless network, then internet won't work. You need to check, and if enabled, then disable manual setting proxy server. Go to settings, which displays a list of Wi-Fi networks, and the network you are connected to. Usually, you need to click on desired network, and hold. A menu will appear in which you need to select something like Change network. Next, most likely you will need to check the box next to the item Additionally. The proxy server setting will appear. It must be disabled. See screenshots, yours may be slightly different.

If there is "manually", then the Internet on the phone will not work.

3 Check the date, time, and timezone settings. These are the parameters due to which the Play Store on Android most often does not work, gray wifi icon, and the Internet does not work in other programs.

Your phone or tablet should always have the correct date and time settings. And also, it is advised to use the 24-hour time format if you have it disabled. Be sure to check these settings on your device. You can set it to automatic.

After the correct settings, the Play Store starts working. It's been verified.

4 There is such an application - "Freedom". If you have it installed, then in the application itself you need to click Stop. And if you deleted it, then install it back, go to the application, click Stop and then you can delete it. I myself have not encountered this, and have not tested it. But, many write that it helps. The Internet is starting to work.

5 Setting automatic IP acquisition. When there are problems with IP, then Android usually does not connect to Wi-Fi at all. But, it doesn't hurt to check.

Open the Wi-Fi settings on the device and go to the properties of your network (as i showed above). Check the box next to Advanced (maybe you don't need to do this), you will see the item IPv4 settings, or something like that. Automatic IP acquisition should be set there - DHCP.

6 I saw reviews that helps a lot setting static DNS addresses. This method helps in cases where you have a gray Wi-Fi icon on your smartphone or tablet instead of blue, and the Market does not work. Also, not all sites may open.

Go to the properties of the desired Wi-Fi network, as I showed above. Check the Advanced checkbox (if it is needed) and find the item IPv4 settings (yours may be slightly different). You must select an item Manually, and find fields DNS1, and DNS2. Write down the following addresses:

DNS can also be changed in the router settings, if it makes it easier for you.

7 More can be done full reset settings of your Android device. If you are not too lazy to set it up again, install applications, etc. But, if nothing helps, then you need to do a reset, this can solve the problem with the Internet.

8 Update. In the comments, they shared unusual tips that helped get rid of the problem with Wi-Fi on Android. The solution is really very strange, but you can try.

It is necessary in the phone settings, as the main memory, select built-in phone memory, not the SD card. I can not specifically suggest where this can be done on your smartphone. Maybe you don't have that feature at all. But look somewhere in the settings, in the "Memory" section.

We change the settings of the router if the Internet does not work on a smartphone (tablet)

Let me remind you once again that the Internet from your router should work on other devices. If it does not work at all, on any device, then you need to configure the router. Android has nothing to do with it. Basically, the tips that I will write below help in cases where the smartphone does not see the Wi-Fi network at all, or does not connect to it. By the way, before setting up, you can try to simply restart the router.

1 Try changing the channel in your router settings. Very often, it is because of the channel that there are problems connecting to Wi-Fi. There is a detailed article on this topic:. You don’t even have to look for a free channel (this is a long time), but simply set some kind of static one, for example - 6. In the article by reference, I showed how to change the channel on different routers.

2 On the same page where you can change the channel, you can usually change the region. These settings are usually located on the page with Wi-Fi settings networks. Set your region in settings.

3 Here you can also try to change the mode of the wireless network. These settings are available on any router. You can try different options. For example, put n only.

This is where you need to experiment. Don't forget to save your settings and reboot your router.
