O.K. - Get ready for purgatory. Att will NOT recognize any other brand of modem other than
att brand and maybe some Motorola ones. The MAC number is not suffucient info. YOu need
to go to the modem manufacturers website and set up a PPPOE connection using your att dsl
user name and password - which is probably DIFFERENT than your att webmail user
name and password. (for me user name is the same but tow diff. passwords. If you can't
figure out how to do all this bull, return your non-att modem and go to an att store and buy
an att modem from the dispicable att corporation for twice as much (probably).
