I' using a Toshiba A70 with a built-in Atheros card (5121 I believe).
I seem to have it working fairly well from the instruction I got from http://madwifi.org/wiki/UserDocs/FirstTimeHowTo
and http://madwifi.org/wiki/UserDocs/Distro/Debian. I mean, by this, that I looked at both and followed bothh pages. In addition to what they write, it is essential that you have the oproper kernel-headers file.
apt-get install (e. g. what I use) linux-headers-2.6.14-2-686-smp
Aside from this, these two pages will get your Atheros card to work, I should think.
Any way, thisd is one solution.
Cheers.
