I have a Archer C80. Wireless router modem, that supports PPOE. I have been using it for more than an year and it was completely fine. Today I reset the modem ( dont ask me why , am stupid ).

I setup the connection, everything was fine , but before the last screen there was error stating

" Found another router " and it gave me three options

- Modem and Router separate

- Modem and Router together

- None

tried all 3. The router says connected, the IP address is assigned but am not able to use the internet. Breaking my head. Same internet, same credentials , same device , just a reset and I dont know what went wrong
