Just got a refurb PB and i'm having problems with my internet connection. I purchased a D Link ADSL modem which plugs into the Airport Express. After configuring the modem and installing Airport Express I tried to get online but it doesn't work even though I get full bars on the signal strength and the Airports light is green. I've connected the Modem directly to the PB which gets me online OK. I've also been able to get online using other networks that are in my building (but have none of the strength of my Airport signal. Any clues to my next step ????? Thanks.
