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.

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!
