Hello All,
I would like to test how maximum WiFi associations are possible on my AP with security mode. The WiFi authentication, association,4-way handshake are OK but I can not get an IP adress for the second interface.
It's works in open mode using WPA supplicant but not with WPA2 AES security mode. I use an ath9k driver (AR9380) and Ubuntu 14.04 (same issue on debian 7)
Could you take a look on the following command line please:
#APUT SSID: Livebox-7650_5
wpa_passphrase Livebox-7650_5 123456789 > temp.txt
sed '1ictrl_interface=/run/wpa_supplicant' temp.txt > my.conf
sudo rfkill block wifi
sudo killall wpa_supplicant
sudo rfkill unblock wifi
ifconfig wlan0 down
iw dev wlan0 del

sudo wpa_supplicant -B -iwlan0 -c./my.conf

I cannot have an IP adress, it stops here....Ok in open security mode using WPA_supplicant. Do you have an idea please?

Are you trying to use multiple stations on a single radio?
If so, you need to disable hardware crypt with module option.
