A buddy of mine just bought a new imac and an airport express. He is having trouble setting up the express though and he doesn't live near me so I can't physically access it. The issue is he can't get the airport utility to find the airport express, and the modem is plugged in correctly and the light is a solid green on the airport express. The part that confuses me is that on every router I have ever setup, you have to be physically connected with a ethernet cable in order to setup the wireless. If this airport express has no ethernet ports for computers, how is he supposed to connect to it so that the airport utility can find the airport express? Is there a default wireless network that airport expresses have available as a default? Thanks.
