Authentication of identity information always fails. What happened?

In the first case, of course, the password entered is incorrect. As long as you re-enter the correct password, you can naturally link to the network! The specific way is to open the wlan interface-long press the SSID of the wireless network to modify the network-and re-enter the password. If not, press and hold the SSID of the wireless network to cancel saving the network, then search the network and re-enter the password! ! ! See the figure below for specific operations:

The second situation is because you are close. How close? In the dormitory next door, upstairs and downstairs. You have used too many routers with different transmission powers, and the default channels of routers are all 6, which leads to mutual interference and authentication problems! Of course, the solution is to change the router channel! Specifically, enter 192. 168. 1 Enter-Wireless Settings-Basic Settings-Channel in the browser and change the drop-down menu! ! !

The third case is that the password is correct, but it still shows that there is a problem with authentication. Generally speaking, this may be a problem with the input method. We'd better use the native input method of Android system to input the password, and pay attention to case! ! ! The specific switching mode-mobile phone settings-language and input method-just choose Android keyboard! ! ! As shown in the following figure

The fourth case may be that the encryption method of mobile phone is different from the encryption method of routing wireless network password. Generally, WPA-PSK/WPA2-PSK is used, and AES is used for encryption, which is mainly safe and not easy to crack. It can be solved by trying more encryption methods. Specific as shown in the figure below:

The fifth situation may be the problem of the mobile phone. The solution is to reset the phone or brush it. I'm sure everyone will say so. It may be the computer and the router. It is recommended to restart the computer or router to restore the factory settings! ! !
