Huh: Earliest failing kernel version:2.6.26 ath9k went in as of 2.6.27. Please provide kernel logs. Also please try to manually configure things, do not use things like sudo /etc/init.d/networking restart to test things, I want to see exactly what userspace is trying to configure. Please have a good read at this guide as to how to report Linux wireless bugs to be able to assist you more efficiently: http://wireless.kernel.org/en/users/Support http://wireless.kernel.org/en/users/Documentation/Reporting_bugs We will need to know your AP configuration, 11N, HT40/HT20, etc.
I tried to configure things manually. I first opened my router, with no WPA protection. I typed : sudo iwconfig wlan0 essid "my_essid" sudo dhclient wlan0 and it worked I tried then, in /etc/network/interfaces : allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp pre-up iwconfig wlan0 essid "my_essid" It worked too. I came back to my first config : # wifi auto wlan0 iface wlan0 inet dhcp pre-up /sbin/ifconfig wlan0 up # tried with and without that line wpa-conf managed wpa-ssid my_essid wpa-psk _my key_ I could make it work ; I had to reinstall wpasupplicant. Thanks for your help. I think I can mark the "bug" as closed. Sorry for the noise.
