Resending in plain text mode... Hi Kalle, I have a custom built board with an AR6003 WiFi chip running linux-3.10.40 and hostapd 2.2 that I'm trying to use as an access point. My configuration file for hostapd is: interface=wlan0 driver=nl80211 ssid=testssid channel=1 own_ip_addr=********** auth_algs=1 wpa=2 wpa_passphrase=********** wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rns_pairwise=CCMP ignore_broadcase_ssid=1 I should mention that this configuration works with a USB WiFi stick with an ath9k chipset running the same linux kernel and hostapd binary. When using the AR6003 chipset the client Laptop (HP EliteBook 8440p running ubuntu 12.04.3 LTS) does not connect and prints the message: wlan0: disassociating from <device mac> by local choice (reason=17) Running Wireshark on the Laptop, I see "Key (msg 1/4)", "Key (msg 2/4)", and then "Key (msg 3/4)" before it tries to reauthenticate. On the access point device, I see the logs from WAP that message 3/4 was sent and the next message received is NL80211_CMD_DEL_STATION. I've searched online for the reason=17 and haven't come across an answer yet. The access point device is not connected to a computer that is connected to the internet, so while getting log files is possible, it 's just not the easiest thing to do. If requested, I could get a log dump from hostapd and/or debug output from the ath6kl driver.
