WiFi authentication error: tablet or phone on Android can not connect to the network

While connecting to the Wi-Fi channel of devices running on the mobile Android platform, there may be various problems, the most common of which is the WiFi authentication error.

The most common problems occur because of incorrect settings in network security or in the mode of the router, as well as the channel that is selected for the operation of the Wi-Fi network. When you try to connect to the network using a tablet or phone on Android, you may see some errors.

WiFi Authentication Failure (Android)

This is an authentication problem where the "Disabled" designation usually appears, and the device does not connect to the Wi-Fi network. Such a device is often a smartphone, but the error of WiFi authentication on the tablet is not less widespread.

Infinite obtaining of IP-addresses

The connection status is as follows: "Obtain an IP address" or "Connection". However, the device does not connect to the network. As you can see, the WiFi authentication error is not the only one, although widespread.

Error "Saved, protected by WPA \ WPA2"

The device running Android OS connects to the router via Wi-Fi, but the Internet still does not work. In the browser sites are not opened. Most often in such cases, the network level indicator is inactive (for example, gray, and before it was blue). Next, we will try to figure out how to fix the WiFi authentication error , and also to resolve all the problems described above.

Problem solving

Before proceeding with making changes to any settings, we recommend simply restarting your device, which refuses to connect. There is a possibility that we are dealing with some kind of malfunction, and restarting the device will help. If it does not help, let's look at other options. In the event that before everything was connected, but now does not want (and you did not change any settings), we recommend changing the channel to work with the wireless network. Perhaps there was a new router nearby, the network of which interfered with the usual connection.

We advise you to go to the settings of the router, after which they change the channel for this Wi-Fi.

This can be done most often in the "Wireless" tab. Or in another place where you usually set the wireless network settings. The procedure is as follows: change the channel number, save the settings, restart the router, and then try to connect.

The device connects, but the Internet still does not work

You see the status "Connected". It seems that everything is correct, but the Internet still does not work. First of all, you need to make sure that the network is actually present on the router. Often, this problem occurs during the first configuration of the router. Connect to Wi-Fi some other device. In the event that it connects, but the Internet does not work, it's likely that we have a problem with the incorrect settings on the router. If another device goes online, try our other tips in action.

WiFi authentication failed: details

If you can see the error on the phone screen that gives the message "Authentication", most likely, it's a problem with incorrectly set security settings, or with an incorrect password. We recommend, first of all, to check the correct password that you specify in order to connect to the network. There is a possibility that you enter it incorrectly.

While writing the password, follow the specified case of letters. If the password you enter is correct, check the settings for security. We set the security type of WPA2. The password is specified exactly 8 symbols. In addition, try changing the mode of your wireless network. You can change it in the same place where we chose the channel (router settings).

Reboot the router and save the settings after each change you make.

It is also worth checking the settings of the region. Select the country in which you are located. Check if the device works with other Wi-Fi points. It is possible that the problem lies in the tablet or phone.

And if the virus?

We did not mention above that the WiFi authentication error can arise due to the violation of system files and dynamic libraries by various malicious programs (in other words, viruses) that attack your mobile device. In such a case, immediately apply complex measures to combat this error. There are several programs that can solve such problems without too much time. Simply follow all instructions of the antivirus program after it is launched. Use only trusted applications, and then the likelihood of all kinds of malfunctions in the mobile device (including the definition of a wireless network) will be significantly reduced.

Perhaps we did not describe the solution for all problems with connecting to Wi-Fi, but tried to dwell on the most common situations. For more information, contact your service provider or service center.
