I was asked to upgrade my father in laws router and after upgrading my own so easily decided to buy him an Archer D20 AC750 modem/router.

I swapped it out for his old Sky DSL router but after many failed attempts have been unable to connect it to the internet. The ISP list shows the only option for Sky as Sky BskyB dsl and when i enter what i thought was the generic PPPoa username and password showed connection failed. I have tried different usernames from other forums but either this is the wrong Modem/Router and doesn't work with Sky or I need some alternative usernames and passwords for the ISP login.

Has anyone used this router successfully to replace a sky router? Setting mine up through BT was a doddle but this has been a nightmare.
