If the DHCP server is shut down, devices such as mobile phones and computers will not be able to obtain IP addresses.

1. Forget the password of the wireless network, and then re-enter the connection, when entering the wireless connection password, if the password is relatively long, it is possible to enter the wrong password, so it is recommended that you enter the password again.
