Hi all, I'm having a problem that I hope someone can help
me out with. I have a Toshiba P25-S507 laptop with a built-in
Atheros based wifi card. I know the card itself works
as it works fine when I boot into Windows (I'm using it
to send this e-mail, actually) and it worked under
Linux with mad-wifi under FC4.
Now I've installed FC6, and I cannot get things
to work. The card will (apparently) associate
with the access point, but I can't get any traffic
in our out on the interface. This is using the
latest (built from SVN sources) madwifi driver.
Here is some more detailed information on my
settings and the nature of the problem:

Any ideas? I'm guessing there is just a mistake in my
configuration somewhere, but right now I'll be darned if
I can figure out what it is.
Thanks,
Phil
