Hi,
I run a TrendNet wireless gaming adapter for my main Xbox360...its their version 1.0 and altho it shows in the 655 status as running .11N, it will only run at .11G speeds. Very stable tho, just not at .11N speeds.
They sell a newer model now, and maybe that has better .11N compatibility ??
I am very happy with my adapter, altho in reality, its more like a self-contained wireless bridge as you can technically run it into a switch to pass signal to more than just a single Xbox or pc....or so the little manual says. It, the adapter, has its own LAN IP, but the XBox uses its own LAN IP, not the adapter's IP.
I got mine from Newegg....was on sale when I got it....
