finally i got the WLan running under Backtrack in the newest Version. I have a laptor with an "intel 2200bg" chipset. Only Kismet won't work. I saw that a lot of users have this problem. So I tried everything I found here, but it still won't work.
I have a tried to start it via: start-kismet-ng -> permission denied.
Then I searched for this error and found this:
# chmod +x/usr/bin/start-kismet-ng
# /usr/bin/start-kismet-ng

I entered those two lines in the shell, but I still get the permission denied error.

When I just write "kismet" in the command line i get an error that I have no packsources enabled.

I'm new in to all of this. Sorry.

Thanks for your help
