I've had pretty good luck with other Linksys products in the past, but this thing will drive you insane. I am using a Dell Inspiron 8200 with XP Home Edition and the new Linksys dual band AP. One day it works, the next day it won't...literally. Lots of bluescreens and hangups. Sometimes XP doesn't even see the hardware in Device Manager?!? I found swapping the PCMCIA slot seems to help sometimes, but the connection is pretty unstable even when you are in the same room as the AP. I've tried changing the channels, SSID, and WAP keys, but the bad behavoir continues. Tech support is clueless..they just lecture you on how you have to be within range of the AP...I'm 3 feet away, not in a lead bunker! Now I am stuck with ..useless hardware. My suggestion? Go buy yourself 100' of cat5 cable and you will be a lot happier.
