So I'm venturing out of lurking land because I need your help Penny Arcade. I have just bought a wireless adapter for the 360 and a Netgear dgn2000 wireless router. I can get the 360 to connect to the router but the connecting is so slow it's rendering online play impossible. The router is only on the next room, I have uPnP turned on, NAT is open and I'm on channel 11 to get the least amount of interference but I still can only join 50 ping rated games in modern warefare 2 for example.
Any ideas of how to solve this would be awesome.
