I wonder if Tom could step in and answer that question.

The only wireless experience I have with Compaq laptops has been good. I had an Armada M700 for a while that I used a Compaq WL100 PCMCIA card in with no issues to multiple access points. The standard here now is the Evo systems with the WLAN card on the back of the screen, again no issues.

Is there a setting like "Use Interference Robustness"? This is a setting the Apple laptops have to help in situations, but it shortens the distance quite a bit. Maybe this is on somehow. I don't have an XP laptop to look at to compare anymore though.

And I can't talk to any resources here, we haven't had a laptop team at this site for a while now.

Sorry, wish I could be of more help.
