Hi all,
I'm trying to update from compat-wireless-2009-06-02 to
compat-wireless-2.6.32-rc1. After the update some clients can
no-longer associate with the access point (mac80211/ath9k/hostapd).
Specifically, it seems windows based clients do not accept the new
association response frame and choke or send deauth.
A tcpdump from a separate machine shows the story. After the update
with compat-wireless-2.6.32-rc1 the dump locks like this (notice the
deauth frame from the XP laptop at the end):

I've also tried some other windows based clients, e.g. a laptop with
an old 11b 3Com PCMCIA card. Most seem to choke from the auth response
or assoc response frame. The hostapd/syslog on the AP side looks
something like this:
MGMT
mgmt::auth
authentication: STA=00:04:75:c4:1e:a5 auth_alg=0 auth_transaction=1
status_code=0 wep=0

[And so on over and over...]
I've also tried some different versions of hostapd: 0.6.9 and two
different git snapshots from 0.7-branch (a35187e71a1dd23653fc03ed5
and 6d6f4bb87f33278aed133875d0d561eb55d7ae59) but it doesn't seem to
make any difference. My configuration file is really simple:
driver=nl80211
interface=ap0
ctrl_interface=/var/run/
hostapd-vtmd
hw_mode=g
channel=1
ssid=demo.venatech.net
ieee80211n=1
ht_capab=
Does anybody recognize this? Any ideas on what to try next? Any help
would be greatly appreciated.
