My room-mates connection is unstable. He will have an "excellent" signal for 5 seconds, then no signal for 5 seconds back and forth. I hae a happy stable connection. We've computed from the same room, I'm fine, his signal is up and down in periodic fashion. We've even sat next to the router and had the same results.
We disabled f-secure on his system and there was no change. I installed the PC cards on each of our notebooks the exact same way.
One thing of note. I run XP pro, he runs XP home.
Any advice or help would be much appreciated.
