it looks like it doesn't have a driver
do you know whether you have madwifi or ndiswrapper installed (modprobe -l)?
if one is, you can start it with modprobe

Thanks for the responses.

There is some madwifi around like this:
/lib/modules/2.6.24-22-generic/madwifi/ath_rate_sample.ko
/lib/modules/2.6.24-22-generic/madwifi/ath_rate_amrr.ko
/lib/modules/2.6.24-22-generic/madwifi/wlan_xauth.ko
/lib/modules/2.6.24-22-generic/madwifi/wlan.ko
/lib/modules/2.6.24-22-generic/madwifi/wlan_scan_sta.ko
/lib/modules/2.6.24-22-generic/madwifi/wlan_scan_ap.ko
/lib/modules/2.6.24-22-generic/madwifi/ath_rate_onoe.ko
/lib/modules/2.6.24-22-generic/madwifi/wlan_acl.ko
/lib/modules/2.6.24-22-generic/madwifi/ath_rate_minstrel.ko
/lib/modules/2.6.24-22-generic/madwifi/wlan_wep.ko
/lib/modules/2.6.24-22-generic/madwifi/wlan_ccmp.ko
/lib/modules/2.6.24-22-generic/madwifi/wlan_tkip.ko
/lib/modules/2.6.24-22-generic/madwifi/ath_pci.ko
/lib/modules/2.6.24-22-generic/volatile/ath_hal.ko

But
mng@mng-laptop:~$ modprobe madwifi
FATAL: Module madwifi not found.

I didn't realize madwifi was a driver. I thought only ath9k was. I will see if synaptic can find it.
Synaptic got the madwifi tools but no madwifi driver.
Is compat-wireless relevant?

sorry
the madwifi driver is ath_pci

I think it was compat-wireless that solved this. It seems to have left me with an ath9k.
Along the way I needed to add the linux-restricted repository

Now I have a whole lot of compat-wirelesses on my desktop like
.sh
.tar.bz2
.old
.deb and
.tar.gz

Can I get rid of them all, or should I keep the one I most likely used ? --
compat-wireless-2.6-old
?

Thanks again.
