Re: User id and password for SBC 2Wire 2700HG-B DSL Router
You said you have DSL service from some local phone coop, not AT&T. So any AT&T username and password is not going to work on your modem. You need to use your username and password for your coop's PPPoE.
Or are you asking about the password to access the modem config. If you do a factory reset, I believe that is cleared to nothing.
