Well, I have recently bought a 360 and Halo 3, and I really want to play online. But I am no where near the internet modem or wireless router, therefore I cannot plug in. And I cant afford a wireless adapter for $100. So I was thinkin', if my computer has a internet jack in the back, and I have a cable to connect the 360 to the computer through that internet cable, could I go online through my computer?
