I too am looking for some router advice, and instead of making a new thread I figured I'd post here.
So that Buffalo looks like a winner.
My setup would be mainly about sharing the internet connection. I plan to hook my main computer and X360 through regular lan cables, since they are close to area where I plan to put it. Wireless part would be for another, less used, computer at the house and possibly a laptop or something. I take it that this Buffalo would be good for this setup? How's the port forwarding in it? I have never used a router that made port forwarding easy, so maybe this is different.
Also, the computer on the other room would need a wireless receiver, any recommendations?
