Hi Everyone,
I own a new toshiba laptop with a AR5006EG card.

I m running Kubuntu 6.06, linux 2.6.15-27-386. I downloaded the svn
snapshot yesterday (svn r1754), unloaded all the ubuntu-provided modules
(new_ath_pci, new_wlan_xauth, new_wlan_wep, new_wlan_tkip,
new_ath_rate_sample, new_wlan_scan_ap, new_wlan_ccmp, new_wlan_scan_sta,
new_wlan, new_wlan_acl, new_ath_hal), make && make install && modprobe
ath_pci
So far so good, everything went fine.

After a couple of seconds, ath0 associates with my access-point, which
happens to be a linux box, with a netgear wifi card running madwifi (svn
r1754 as well).

I can now get an IP by running the dhcp client.
However, things start to go wrong when I bring down the ath0 interface, or
when the laptop is disassociated from the AP (for example if the AP goes
down). In these cases, I cannot reassociate with the AP. Here is an
example:

As you can see, even if I used iwconfig to configure the AP bssid and
essid, I still cant associate with it(no bit rate and link quality
values). However, I noticed the Rx invalid nwid counter keeps increasing
rapidly. The only way to solve this, is to rmmod ath_pci && modprobe
ath_pci...
I also noticed that if I run hostapd on my AP, then the laptop fails
associating with the AP right after modprobing ath_pci, and there is no
way to associate the two with hostapd running...
Has someone got any thoughts on this issue ?
Thanks
Gilles
