[Tutorial] Fix: Compat wireless - 'fixed channel mon0: -1'

[SquirrelScript]

After upgrading to Ubuntu 10.10, I found that airodump-ng and aireplay-ng didn't want to work:

airodump-ng: Fixed channel to -1 = fixed channel mon0: -1
aireplay-ng: Wouldn't false authenticate OR deauth = mon0 is on channel -1, but the AP uses channel 9

Setup
OS: Ubuntu 10.10
Kernel: 2.6.35-22-generic-pae
WiFi Card: Intel iwlwifi iwlagn Intel Corporation WiFi Link 5100

How?

wget http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-10-16.tar.bz2
tar -jxf compat-wireless-2010-10-16.tar.bz2
