I used to play in the living room where I can easily connect my Xbox 360 to the internet by plugging in an Ethernet cable into a wireless router.

But now I play my Xbox in the basement because I got a new TV. To connect my Xbox to the internet, I plug the Ethernet cable onto my laptop which connects to the router which enables me to use XBL. The catch is my parents always use the laptop and I hate getting interrupted when playing on XBL.

I think spending $100 on a wireless adapter which should have been built-in on the Xbox is ridiculous. I need the money to buy games, not for an add-on that should have been on the Xbox in the first place.
