[ath9k-devel] WPA/WPA2 problem with ath9k

[Tamas Selmeci <tselmeci@dension.com>]

Hello all!

On our hotspot apart from Samsung mobiles everything is ok until there's 
no security switched on.

As soon as WPA/WPA2 (or any combination of them including TKIP/CCMP) is 
switched on, connecting to the AP becomes extremely slow and fails 
several times. Once it gets connected seems to work perfectly, but I 
can't beleive that it should be that slow.

Environment:
- linux-2.6.27-rc6;
- ath9k-compat: 2009-01-25 and 2009-02-11;
- AR5416
- hostapd-0.6.7

hostapd.conf is as follows:

interface=wlan0
driver=nl80211
hw_mode=g
country_code=DE
max_num_sta=32
# supported_rates=10 20 55 110 60 90 120 180 240 360 480 540
# ht_capab=[HT40-][SHORT-GI-20][SHORT-GI-40]
logger_syslog=1
logger_syslog_level=0
logger_stdout=-1
logger_stdout_level=0
debug=1
ctrl_interface_group=0
macaddr_acl=0
auth_algs=1
dump_file=/tmp/hostapd.dump
ssid=norbolataska
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP
rsn_pairwise=TKIP CCMP
ap_max_inactivity=120
wpa_psk=af8f7d04a3331126ee9fad0cf2dbba54728389d93d83ca1549dfda2727249890
channel=8

Do you have any idea what can be wrong? I heard that AR5416 is a rather 
buggy card, many of the bugs have been fixed in AR9160, but that's also 
problematic according to my experiences. Adding "ieee80211n=1" didn't 
solve the problem.
