XBox to Laptop Wireless

Alright, so my room isn't wired with Ethernet, so I went ahead and plugged my cable into my laptop, hoping that I could run Live off that instead.

I unchecked the network sharing in my wireless connection, and then proceeded to bridge the wireless and local connections. It worked, and for the first couple of days, XBL worked fine, without problems.


But for the last 12 hours or so, my connection on my XBox (only the XBox...) has been cutting in and out every 10-15 minutes. Do I need to try and work out ICS? Or is it simply a matter of forwarding ports? Any ideas?
