I am trying to set up my 3rd party router (Asus RT-AC1200GU) instead of default Sagemcom. Optus support team informed me that it only should require OptusNet (email) username and password...
I tried using PPPoE with my credentials, but the router doesn't connect. I even tried to connect my laptop directly into the phone line with PPPoE configuration, but the laptop fails to connect.
What am I missing? Are there some advanced settings required?
