Why is the mobile phone slow to use wireless network?

If you use an OPPO phone, you can refer to the following methods:

First, all Wi-Fi access is slow;

1. Due to the shielding and anti-interference characteristics of electroplating, metal, magnetic and other protective cases, the mobile phone signal will be poor or unstable. As you are not sure whether your protective shell contains this substance, it is recommended to remove the protective shell to see if it can return to normal;

2. If all Wi-Fi hotspots are slow to access the Internet, I suggest you try to switch flight modes or restart your mobile phone to see if you can solve the problem.

3. If you can't solve the problem after switching flight modes or restarting, you can try to restore only the system settings (ColorOS 5-ColorOS 7 system)/wireless settings (ColorOS 1 1 and above) in the settings, and try to turn on the Wi-Fi switch again.

Second, some Wi-Fi access is slow;

1, remove the phone case;

2. If some Wi-Fi is slow to access the Internet, it may be caused by being far away from the hotspots of Wi-Fi, the weak signal strength of the connected Wi-Fi or the network problems of Wi-Fi itself. Suggest trying to restart this WiFi router or choose a strong Wi-Fi connection and keep it at? Within the effective distance of Wi-Fi hotspot, avoid automatic disconnection due to weak network signal caused by too far distance;

3. If you can't access the Internet after connecting Wi-Fi hotspots in public places (hotels, restaurants, airports, stations, etc.). ), general public hotspots need to open a browser and enter authentication information. If the authentication is unsuccessful, please try to surf the Internet after the authentication is successful;

4. If the Wi-Fi at home can't access the Internet, please try to open private DNS, and then try to connect to the network again. If it was turned on before, please try to restore it after turning it off (path: Settings > Connect and * * * Enjoy > Private DNS);
