What should I do if I can't connect to WIFI?

Possible reasons and solutions for mobile phones unable to connect to the WiFi network:

1. First check whether the wireless router is working properly. You can use other mobile phones or digital products to connect to the WiFi network. If the WIFI signal can connect normally and access the Internet normally, then generally speaking, this router can work normally.

2. The mobile phone is in sleep mode and the network is turned off.

Check whether the option of turning off the network during sleep mode is enabled on the phone. The possible reason why the phone will be disconnected after a while or cannot receive the background chat software is that the function of turning off the network when the phone sleeps is turned on by mistake.

3. If the router is used for a long time, the router may appear to be suspended. Just restart the wireless router.

4. The authentication type is inappropriate. Try to change the authentication type of the router, it is better to choose the secure "WPA2-PSK" type mode, and it is better to choose "AES" for the following encryption algorithm.

5. The network settings of the mobile phone or router are abnormal. Consider restoring the router's factory settings and mobile phone network settings.
