ERROR: Packet source 'wlan0' failed to set channel 2: mac80211_setchannel() in Kismet and Ubuntu 12.10

I have installed Ubuntu 12.10 in my computer with an Atheros AR5007 wireless card.

I want to use Kismet but when I run it it starts displaying the message:

ERROR: Packet source 'wlan0' failed to set channel X: mac80211_setchannel()

It keeps displaying the same for every channel except channel 1. I have installed the compat-wireless-3.6.6-1 drivers and patched them with the following patch in order to use them with aircrack-ng.

I have installed the latest version of Kismet in the git repository and I even tried with the svn but it keeps displaying the same error. I also have set the kismet.conf file with the nsource=wlan0 as it is the name of my wireless interface according to iwconfig :

lo        no wireless extensions.



wlan0     IEEE 802.11bg  ESSID:"XXXX"  

          Mode:Managed  Frequency:2.412 GHz  Access Point: XX:XX:XX:XX:XX:XX   

          Bit Rate=18 Mb/s   Tx-Power=20 dBm   

          Retry  long limit:7   RTS thr:off   Fragment thr:off

          Power Management:off

          Link Quality=28/70  Signal level=-82 dBm  

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0

          Tx excessive retries:0  Invalid misc:282   Missed beacon:0

I haven't found any answer since similar errors are supposed to be fixed with the latest Kismet release but this isn't my case. Any help will be appreciated.

Thank you!

I believe ncsource=wlan0 is correct.

Some cards have trouble switching to monitor mode seamlessly at the command of Kismet.

I have to do:

sudo ifconfig wlan0 down

sudo iwconfig wlan0 mode monitor

sudo kismet

I also notice the channel lists include 802.11a channels; if you know your card doesn't do 802.11a, you might comment out those lines in kismet.conf.
