Alright, I already asked this question, but it wasn't really clear to me. I have a router in my game room and I use that router for internet in my room for this computer. The device in my room looks like this:

I guess this would be called the receiver or something, but would I be able to plug this little device into an xbox 360 and get internet on my xbox that way? I've asked people and I've heard mixed answers. Some people say it will work, but some tell me that I have to buy something from Microsoft that costs like $100, and I'm not going to spend that much on a little device to get wireless.
So would plugging this thing into my xbox give my wireless internet if I have a router in my game room?
