I'm having lots of problems using my DIR-655 I just bought with my Toshiba Satellite A500. I tried it with my girlfriends macbook and buddy's older Satellite and it works totally fine. From about 4 feet away I still have little points where it cuts out momentarily. If I make it about 10 feet its horrendous. Gigabit works totally fine though, plugged right into the ethernet it works great.
