I just got a cable modem which works when connected directly to the computer. When I connect the modem to my airport extreme router and then the router to the computer I get no internet connection at all. Any suggestions?
HI - first a few questions - is the cable modem just a modem or is it a router also? - and what version of the Airport Utility are you using to setup the Extreme? - and what color is the light on the Extreme and is it blinking?
