Why does the mobile phone always display the network connection timeout? It is connected to a complete wireless network.

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

2. The mobile phone is turned on and the network is turned off.

Check whether the option to turn off the network is turned on when the phone is dormant. The phone will be disconnected after a period of time or may not receive background chat software. The possible reason is that the function of closing the network when sleeping is turned on by mistake.

3. If you use the router for a long time, the router may be in suspended animation. Just restart the wireless router.

4. The authentication type is not appropriate. When trying to change the authentication type of the router, it is best to choose the secure "WPA2-PSK" type mode, and the following encryption algorithm is best to choose "AES".

5. The mobile phone or router network settings are abnormal. Consider restoring router factory settings and mobile phone network settings.
