When connecting devices using the Android mobile platform to the Wi-Fi channel, various problems can occur, the most common of which is the WiFi authentication error.
Most often, problems arise due to incorrect settings in the network security or in the router’s operating mode, as well as the channel that is selected for the Wi-Fi network. When you try to connect to the network using a tablet or Android phone, you may see some errors.
WiFi Authentication Error (Android)
This is an authentication problem, which usually means “Disabled” and the device does not connect to the Wi-Fi network.
A smartphone is often such a device, but a WiFi authentication error on a tablet is no less common.
Infinite IP Addresses
The connection status is: “Obtaining 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, although common.
Error "Saved, protected by WPA \ WPA2"
A device running Android OS connects to the router via Wi-Fi, but the Internet still does not work. In the browser sites do not open. 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 , as well as eliminate all the problems described above.
Solution of problems
Before you start making changes to some settings, we advise you to simply restart your device, which refuses to connect.
There is a possibility that we are dealing with some kind of failure, and rebooting the device will help. If it doesn’t help, let's consider other options. In the event that everything was connected before but doesn’t want to (but you haven’t changed any settings), we recommend changing the channel for working with a wireless network. Perhaps a new router appeared nearby, the network of which interfered with the usual connection.
We advise you to go to the settings of the router, and then change the channel for this Wi-Fi in them.
This can be done most often in the “Wireless” tab. Or in another place where you usually set up wireless networks. The procedure is as follows: change the channel number, save the settings, reboot the router, and then try to connect.
The device is connecting, but the Internet still does not work
You see the status "Connected". Everything seems to be correct, but the Internet is still not working. First of all, you need to make sure that the network is really present on the router. Often a similar problem occurs during the first setup of the router. Connect some other device to Wi-Fi. If it connects, but the Internet refuses to work, most likely we are faced with a problem with incorrect settings on the router. If another device goes online, try our other tips in action.
WiFi Authentication Error: Details
If you can see an error on the phone screen that displays the message “Authentication”, most likely, we are talking about problems associated with incorrectly configured security settings, or with an incorrect password.
We recommend, first of all, to verify the correctness of the password that you set in order to connect to the network. There is a chance that you enter it incorrectly.
When writing a password, adhere to the specified letter case. If you enter the password correctly, check the settings for security. Set the security type to WPA2. We specify the password exactly 8 characters. In addition, try changing the mode of operation of your wireless network. You can change it in the same place where we selected the channel (router settings).
Reboot the router and save the settings after each change.
It is also worth checking the region settings. Indicate the country in which you are located. Check if the indicated device works with other Wi-Fi points. It’s possible that the problem is with the tablet or phone.
What if the virus?
We did not mention above that a WiFi authentication error can occur due to violation of system files and dynamic libraries by various malicious programs (in other words, viruses) that attack your mobile device.
In this case, immediately apply comprehensive measures to combat this error. There are several programs that can solve such problems without much time. Just follow all the instructions of the antivirus program after it starts. 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.
