OPPO A57 4G

Android 12.0

I can't use Wi-Fi on my OPPO A57 4G Android 12.0

Cause 4 of 4: The selected Wi-Fi network rejects the connection

If the Wi-Fi network rejects the connection, it may be due to a Wi-Fi network error or that you don't have the correct connection credentials.

Solution: Contact the administrator of the Wi-Fi network to obtain the correct connection settings.
