I have the DLink .11B bridge on mine right now. Honestly, I've noticed no difference between it and when I was hardwired, although I've played very little Live in the past couple months.
You can run the little speed test in the dashboard, and I was getting somethign like 4000/1000 before(for example), but with wireless I get 1000/1000. So I guess my upload is maxed out anyways, which is the most important part of staying lag free.
I just can't wait till NFL 2K5 comes out, I'm gonna burn out that damn bridge playing online so much!
