I am connected wirelessly with my Xbox to my router using the N adapter. It works perfectly fine for me while gaming, streaming media from my PC and watching Netflix. It is for that reason I said the router has to be the bind. Cause it does work and I didn't have to go through anything like you did. I just plugged in my adapter, searched for my network, typed in my password and away I went. No port forwarding, no nothing. It just worked
