So I need help setting up someone's Airport Extreme. They are on Primus. I can get an Internet connection from the modem when I connect it to a PC. But when I connect the Airport Extreme to the modem and walk through the base station setup on a iMac the amber light continues to blink on the basestation. In the airport utility is showing Internet connection and yellow right now.

I am stomped right now and help would be greatful

It looks like Primus uses PPPoE...so you'd need their user name (something@1mm.primus.ca) and password log into their account when you connect to the modem.

I got it working. I don't know how really but the light is green and internet and wireless are working. Thanks.
