Apple mobile phone can not connect to WiFi reasons and solutions:
1. First check whether the wireless router works properly, you can use other mobile phones or digital products to connect to the WIFI signal, if you can normally connect and surf the Internet, then generally speaking, the router can work normally.
2. Turn off the network by enabling the sleep state of the mobile phone. Check whether the option to turn off the network in the sleep state is enabled on the mobile phone. After a period of time, the mobile phone will be disconnected or cannot receive the background chat software. The possible cause is that the function of turning off the network in the sleep state is enabled by mistake.
3. If you use the router for a long time, the router may be suspended animation. Restart the wireless router.
4. The authentication type is inappropriate. Try to change the authentication type of the router. It is better to select the secure WPA2-PSK mode, and the following encryption algorithm is best to select AES.
5. The network Settings on the mobile phone or router are abnormal. Consider restoring router factory Settings and cell phone network Settings. 6, if the above methods can not solve the problem, please contact the local Apple after-sales service for repair and processing
