I have a Mac, airport express, and a broadband cable which works when i use it with PC. when I plug it into Aorport express and try setting it up using automatic settings it doesnt connect. what do i need to do??
You'll need to supply more details - what happens to the light on the front of the AE, what is the Airport Utility saying. Are there any console errors etc. Soft & hard resets aren't a bad idea though.
