Finally i got my new Airport Extreme basestation and i want to replace my old Linksys Router (Linksys Compact Wireless-G Broadband Router WRT54GC).

anyone knows how the settings could be done ?

in the Airport Setup Assistant and set it up using the
"I use DSL or cable modem using PPP over Ethernet (PPoE)",

which appears to be the only appropriate choice, I get the message "Looking for PPoE Host" but the basestation doesn't connect to anything ?

p.s. i believe that i dont need a modem coz my old linksys doesnt have one and it works.
