Hey, I don't have a wireless network in my home and want to set one up so I can play Xbox Live from my room... and my G4 iMac which is way on the other side of the house doesn't have built-in 802.11 so I need to buy a wireless router. If I buy the Xbox 360 wireless adapter and an Apple Airport Express will they work together? And I read that you can use the Express like a router, so do you just plug it into a wall outlet and connect it through ethernet to your iMac, or your cable modem? Or how does it work. Thanks!
