How are you starting wpa_supplicant? Are you using -Dnl80211? If so, please use -Dwext for the time being.

Hello all

with the entry wpa-driver wext in my interfaces file the network works approximate 2 hours then the wlan stops again.

i found the following entrys in my wpa_supplicant.conf

cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
eapol_version=1
ap_scan=1

network={
ssid="myssid"
key_mgmt=WPA-PSK
proto=WPA
pairwise=TKIP
group=TKIP
psk="mywpapassword"
}

Thanks for the information. The following information will be helpful to debug this issue.

can you post rate stats?.

cat <debugfs_root>/ath9k/phyX/rcstat

Also, do you see any change in tx/rx interrupt counts when the issue happens?. Read interrupt stats few times in a second interval when the issue happens and post them.

cat <debugfs_root>/ath9k/phyX/interrupt >> <dest_file>
Comment 6 vasanthakumar 2009-07-14 04:46:01 UTC 
Also, can you please post dmesg and lspci output?.
