Actually, it seems like it's working fine for me. I'm using a Linksys
WPC11 card with prism2 drivers, on Red Hat 8.0 (updated 2.4.18-18.8.0
kernel), and Kismet 2.8.0b (yeah, XML is broken, but i can live with
that for the moment).

I didn't do a lot of testing though, just discovered a few APs and
rogue clients by simply watching the signal strength. I might have been
just lucky.

I'll do some more testing, and let you know if i have any problems.

Well, if you're familiar with HAM Radio and RF stuff, there's a
game that radio amateurs play: they hide a transmitter somewhere and
dare others to discover it. If you have a directional antenna on a
portable receiver, it's actually quite simple. But it's completely
doable (albeit slower) even without a directional antenna; in that
case all you need is a good real-time reading of the RF field strength
(actually, you need that regardless of having or not having a
directional antenna).

The latter method is what i'm using to discover the APs so precisely
that i can actually touch them. :-) It works even in buildings with
multiple floors.

P.S.: I don't mean to be rude, but your mailer has a funny way to format
the messages. It looks like it does not wrap the lines at 72...78
characters.
