Description:
After setting mon0 to a specific channel, injection test with aireplay-ng shows that mon0 is channel hopping.

I think this problem began after update to kernel 2.6.35 (stock Arch kernel).

Additional info:
* package version(s)
aircrack-ng 1.1-1
kernel26-2.6.35-4
madwifi-0.9.4.4133-2

Steps to reproduce:
As root,
1. airmon-ng stop wlan0
2. airmon-ng start mon0 3
3. aireplay-ng -9 -e "theSSID" -a xx:xx:xx:xx:xx:xx mon0

Output:
09:52:12 Waiting for beacon frame (BSSID: xx:xx:xx:xx:xx:xx) on channel -1
09:52:12 mon0 is on channel -1, but the AP uses channel 3
This task depends upon

This sounds like either a bug in the kernel networking or in aircrack. Can you file a ticket with the aircrack project and link to it? I don't think there's any action I can take here.

I solved it by installing the compat-wireless package with a patch. *** tested with driver 'ath9k'***
compat-wireless stable 2.6.35-1: http://wireless.kernel.org/en/users/Download/stable/
patch: https://patchwork.kernel.org/patch/103589/

Steps:

1) I installed the recommended packages: wireless-regdb, CRDA, iw.
2) Prerequisites. Install: kernel26-headers
3) $ tar -xf /path/to/compat-wireless-2.6.35-1.tar.bz2
4) Patch: $ patch -Np1 -i Path-for-fixed-channel-issue-in-aircrack-ng-suite-V2.patch
5) $ cd /path/to/compat-wireless-2.6.35-1
$ ./scripts/driver-select <driver-name>
$ make
$ sudo make install
6) Reboot

Remember kill the processes that can cause problems:
$ sudo airmon-ng check
$ sudo killall NetworkManager wpa_supplicant

So I guess we can close this now as it doesn't seem to be related to the aircrack-ng package itself at all?
