I have taken a new BSNL ftth 777 plan, and they have provided a "Sharp Vision" modem with default SSID and password for wifi. Everything is working fine including speed. Now I have changed the SSID and password to my liking. Whenever I restart the modem, the SSID and password reset automatically to the earlier one provided by BSNL. This is frustrating as I have to change again after every restart. Any solution please? thanks
