To make Network Manager ignore your wireless cards in Kali 2.0 Sana which prevents Network Manager from interfering with Airmon-ng and other applications that create a monitor mode interface(I know that check kill also stops this issue but it also stops Network manager from managing your eth0 or other wired connections which can be a problem) this fix is very easy to implement as is also easy to reverse just follow the steps:
1. Open /etc/NetworkManager/NetworkManager.conf or command line $leafpad /etc/NetworkManager/NetworkManager.conf
2. Add the following to the bottom of the .conf file:
[keyfile]
unmanaged-devices=mac:<your wireless interface mac address here>
If you have more then one wireless interface that you would like ignored just add a
; (semicolon) and repeat mac:<interface mac address> as follows for as many as your need.
[keyfile]
unmanaged-devices=mac:<your first interface mac here>;mac:<your second interface mac here>
Note: you can also use:
unmanaged-devices=interface-name:wlan0 or any interface you want ignored.
P.S. Please comment any issues this process might cause i have not found any yet but i'm open to input.
