The first Xbox 360 didn't have built in wi-fi, it only had a wired Ethernet port. They did sell a USB WiFi adapter but people got around this by sharing their connection on their laptop and then plugging the Xbox into the laptop via network cable. eBay con merchants were actually selling 'xbl without buying a WiFi adapter' and all you got is instructions on how to share your connectionwhat is the wireless adapter? I use XBL from the console via Wi-fi or Lan? Nowt else?
Edit: just seen thread date, so possibly doesnt apply anymore
