How to reset network settings of your Android phone
Resetting network settings returns your phone’s network settings to their default state. It clears your phone’s saved Wi-Fi connections, Bluetooth devices, and VPN configurations. Everything must be set up from scratch. If you can’t remember your home or office Wi-Fi password, check it on your phone and save it to a good password manager before performing a network reset.
