A lot of users, when trying to connect their Android smartphone or tablet to a Wi-Fi network, encounter many different problems and errors. In this article, we will try to deal with the problem that appears after connecting the Android device to Wi-Fi. When Wi-Fi does not work on a smartphone or tablet. More precisely, the Internet does not work when connected via wireless network. A very popular problem.
We connected our smartphone to the home Wi-Fi network, or at work, there is a connection, but the Internet does not work. Websites do not open in the browser, Google Play Store does not work, other applications that require 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 the YouTube video does not play. Typically, 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 doesn’t work on their smartphone, what they mean is that Android connects to Wi-Fi, but doesn’t 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 other articles. Or, check your router if it is . Now we will look at exactly the case when an Android smartphone connects to Wi-Fi without problems, but problems arise with Internet access.
In fact, there are many reasons and solutions. The whole difficulty is that the problem can appear either due to some problems in the settings of the tablet or smartphone itself, or because of 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.
If you have a tablet, then these tips will also apply.
1 First of all, you can try turning off/on Wi-Fi on the device. Enable/disable airplane mode. Reboot your smartphone. Sometimes it helps.
2 Checking proxy server settings. If a proxy server is enabled on your smartphone in the properties of your wireless network, then the internet will not work. You need to check, and if it is enabled, then disable it manual setting proxy servers. Go to settings, where a list of Wi-Fi networks is displayed, and the network to which you are connected. Usually, you need to click on the desired network, and hold it. A menu will appear in which you need to select something like Change network. Next, you will most likely need to check the box next to Additionally. The proxy server setting will appear. It should be disabled. See screenshots, yours may be slightly different.
If it is set to “manual”, then the Internet on the phone will not work.
3 Check the date, time, and time zone settings. These are the parameters due to which the Play Market most often does not work on Android, wifi icon gray , and the Internet does not work in other programs.
Your phone or tablet should always have the correct date and time settings. It is also recommended 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 correct settings, Play Market starts working. This has 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 haven’t encountered this myself and haven’t tested it. But many people write that it helps. The Internet starts working.
5 Setting up automatic IP acquisition. When there are problems with IP, Android usually does not connect to Wi-Fi at all. But it doesn't hurt to check.
Open the Wi-Fi settings on your device and go to the properties of your network (as I showed above). By checking the box next to Advanced (you may not need to do this), you will see the item IPv4 settings, Or something like that. It should be set to automatically obtain IP - DHCP.
6 I saw reviews that help a lot of people setting static DNS addresses. This method helps in cases where you have a gray Wi-Fi icon on your smartphone or tablet instead of a blue one, and the Market does not work. Also, not all sites may open.
Go to properties required Wi-Fi networks, as I showed above. Check the Advanced box (if it is needed) and find the item IPv4 settings (yours may be slightly different). You need to select an item Manually, and find the fields DNS1, And DNS2. Write the following addresses in them:
You can also change the DNS in the router settings, if it makes it easier for you.
7 You can do more full reset settings of your Android device. If you are not too lazy to configure it again, install applications, etc. But, if nothing helps, then you need to reset it, this can solve the problem with the Internet.
8 Update. In the comments, they shared unusual tips that helped get rid of the Wi-Fi problem on Android. The solution is really very strange, but you can try.You need to select in the phone settings as the main memory phone's built-in memory, not an SD card. I can’t specifically tell you where this can be done on your smartphone. Maybe you don't have such a function at all. But look somewhere in the settings, in the "Memory" section.
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 at all Wi-Fi network, or does not connect to it. By the way, before setting it up, you can simply try rebooting the router.
1 Try changing the channel in your router settings. Very often, it is because of the channel that problems arise with connecting to Wi-Fi. There is a detailed article on this topic:. You don’t even have to look for a free channel (this takes a long time), but simply install some static one, for example - 6. In the article at the link, 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 Wi-Fi network settings page. Set your region in settings.
3 Here you can also try changing the wireless network operating mode. These settings are available on any router. You can try different variants. For example, put n only.
Here you need to experiment. Don't forget to save the settings and reboot the router.

Description:
Today, wireless networks help not to fall out of sight and constantly stay in touch, opening access to the Internet and providing 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 you stay out of sight and constantly stay connected, providing 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 the tablet to Wi-Fi router? To do this you need to do the following:
1. Check the 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. Listed available networks select a router (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 one doesn't connect to wifi router, that is, 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 hotspot. 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 a situation where your tablet does not connect to a wifi router from zyxel, Rostelecom, Beeline or Asus, and if such a problem happens, you can deal with it yourself.
All modern tablets and mobile devices have a built-in module by default that is responsible for connecting to Wi-Fi. However, the inability to connect to Wi-Fi does not always mean that the module is faulty; sometimes the problem may lie in the software part of the device.
The tablet and smartphone usually connect to Wi-Fi immediately if the corresponding function is enabled in their settings. Connection may not occur for several reasons:
In fact, there are not many reasons why a tablet may not see and/or connect to a Wi-Fi network. Some of them you can solve on your own, in other cases you will have to turn to the manufacturer of the device or router for help.
If you or the owner recently changed any router data, for example, the Wi-Fi password or some protocols in the modem firmware, then you may encounter the problem of the tablet being unable to connect to a wireless network.
Fortunately, this problem solved quickly:
Wi-Fi may not work on the tablet also due to incorrectly configured date and time. However, this very rarely causes problems with connecting to the global network.
The solution is to set the date and time correctly:
If you suspect that the problem is in the tablet itself, then try to get an answer on this issue from the device manufacturer. Perhaps they will recommend a service center to you or tell you which additional settings can be done to get rid of the problem.
Let's consider appealing to technical support Samsung:
This is the most extreme method, which is recommended to be used if you have already tried everything and nothing has helped. It is also worth understanding that if you reset the settings yourself, you lose not only all user information, but also the warranty on the device.
If you still decide to reset the settings, then use this step-by-step guide:
It is worth understanding that the method of resetting the settings to factory settings does not always help. For example, if the problem is in the router or in the hardware of the tablet, then this method will be useless.
Some of the methods discussed will help you find out the cause of malfunctions in the tablet and solve it using tips from the manufacturer. It is also possible that the tablet will have to be returned to a service center.
Your tablet does not see the Wi-Fi network, or the connection fails? Is the signal weak or unstable? One or more problems indicate that there are problems with the mobile device and/or network equipment. To solve the problem, we have prepared comprehensive material where you will find the cause and method of eliminating the breakdown.
When using the Internet, the chain consists of a provider, network equipment and the user device. Therefore for quick solution problems, it is important to determine on which side the malfunction occurred.
Find out if there are any interruptions in the availability of the Internet on the part of the provider. To do this, connect the Ethernet cable to network card computer or laptop. If this is not possible, call your provider and ask if there are any interruptions in the Internet at your address.
Connect another device to the router, preferably with the same Wi-Fi module specification. If other equipment connects and works fully, the problem should be considered in the mobile device.
Connect the tablet to other points Wi-Fi access. An unsuccessful connection indicates problems with mobile device. If the connection cannot be made only with the home router, then the problem must be looked for in the equipment used.
If there is no Internet, report the problem to your service provider. If the breakdown cannot be resolved remotely, call a repairman at home, for example, to replace the Ethernet cable. A reason to think about replacement if you live in an apartment building and the cable is laid outside. It's important to note that most providers have tools to remotely diagnose cable integrity.
If the Internet is provided through a telephone line, check the operation of the modem. Connect the equipment directly to your PC or laptop, check the connection settings. If there is no result, take the modem to a service center for diagnostics.
A router is a miniature computer, so failures and system errors during operation are inevitable. In this case, the problem is solved by restarting the system. It is advisable to turn off the power for 2-3 minutes.
For the Internet to work correctly, you must set the correct settings in the management console. This procedure is required if you are setting up the router for the first time. The settings should be rechecked periodically, as failures often lead to settings being reset.
In the settings, it is important to activate the “wireless router broadcast” and “SSID broadcast” functions. Also enable the DHCP protocol if the option was not previously activated.
If the router settings have a fixed channel, it is recommended to change the value or set the mode to auto. If used auto mode, reboot the router to automatically change to a less busy channel.
Some routers allow you to work only in one or two broadcast bands - 2.4/5 GHz. If frequency range the router and the tablet do not match, the connection will not be established. Therefore, set the frequency in the router settings that is supported by the tablet.
Sometimes, when blocking unwanted consumers, it is easy to mistakenly add your own tablet to the blacklist, which will not allow you to connect to the Wi-Fi network. If your router list contains blocked MAC addresses, check the corresponding value in Wi-Fi settings. Check the data and, if necessary, remove the MAC address from the blacklist.
You won’t be able to use a Wi-Fi network if the router is loaded with another connected device – a PC or laptop. Then you need to limit the speed or temporarily stop downloading/uploading information.
Take care of acceptable temperature conditions. If your router is overheating, consider active or passive cooling.
If the access point appears and disappears from the "available to connect" list, or the connection is lost after connecting, the transmitter power is likely muted. Open your router settings and increase the transmitter level. If the router antennas are of a replaceable type, install a reinforced version.
Sometimes viruses and system failures prevent you from changing settings. When changing parameters, the values are saved, and after moving to other settings, they return to their original position, which makes the setting meaningless. In this case, it is recommended to set the parameters manually from scratch.
If the reset did not affect the operation of the router, then it is worth updating the firmware. If there is no result, have the router repaired or think about buying a new device.
A common error when connecting to an access point is wrong password. By default, the tablet settings are set to “hide password”, which makes it easy to make mistakes when entering. Therefore, it is recommended to allow the display of the password, as well as take into account the case when entering characters.
Sometimes it occurs in the tablet system failure, which does not allow you to connect to the network, or the connection is successful, but there is no access to the Internet. In this case, restarting the operating system usually helps.
To save energy, most tablets are equipped with power saving modes. Typically, the effect is achieved by disabling modules that actively waste power, including Wi-Fi. Therefore, it is recommended to deactivate the corresponding mode or use a performance preset.
If the tablet is designed to work with the 2.4 and 5 GHz bands, it is recommended to set the band to automatic selection. Also, do not use the “hide access points with weak signal” option, because when weak signal router, it will not connect.
Improve often Wi-Fi work Changing the firmware or radio module helps. If problems with connecting to Wi-Fi began after flashing, it is recommended to return the originally used firmware back.
If the above methods are unsuccessful, then replacing the motherboard with a working module will solve the problem. In some tablets, the Wi-Fi module is presented as a separate board. Then there is no need to change the motherboard, just unsolder the old module and solder in a new or used one, but in good condition.
Often it is not possible to find a suitable module. In this case, “implantation” helps. USB WiFi module as in the images below. One end of the wire should be soldered to USB contacts, second to contacts on motherboard. If there are no markings near the soldering points, you should first find a diagram.
When using the Internet, the chain of participants consists of three links - the provider, network equipment and the user device - a tablet. To quickly resolve connection problems, it is important to determine which link the fault occurred. The article contains detailed troubleshooting methods if the tablet does not connect to wifi. Solutions are grouped into categories for step-by-step execution and better understanding for beginners and advanced users.
