Any advice would be great.... Can i an Airport Express / Extreme to Output data through it's Ethernet port...? I have an ASDL router on it's way and want to make the iMac wireless. For the price of an origonal Airport card i could (nearly) get an Airport Express / Basestation and would be able to use it with future Apple hardware purchases...... The idea being, connect the iMac to the Base Station through it's ethernet port and recieve internet / network though that. does this sound possible...?
