I live in a dormitory. This building has wi-fi all throughout. I pay for the wireless and and use it on my laptop. I have connected my 360 to my laptop with a cat5 cable and I'm able to access Xbox Live with it. I can play any games perfectly fine. It allows me to use in game chat for games that have that feature. However, I'm unable to join any parties and my friends are unable to join mine. We all checked our settings and we are all running on open NAT. Somebody please help me lol I'm at the limit of my tech skills here.
