My sister is giving my son her old Powerbook G4 laptop with an airport card installed and I need to figure out how to set up for wireless. I have and eMac with a 2wire modem that does not have wireless capability. I called AT&T and they suggested purchasing a new 2wire model # 2701 and then call them for all the configurations, but I was wondering if purchasing an airport express will work and how I would hook it up. Any help would be greatly appreciated. I know I'm way behind the curve with wireless technology.
