If you evoke airmon-ng check kill in kali2.0 and then try and restore NetworkManager later on thru such commands as:
service NetworkManager restart
service network-manager restart
service wpa_supplicant restart
You will find full functionality of the wireless menus does not occur.
There is a better way:
Instead of using airmon-ng check kill try killing the processes thru pgrep.
Enter
pgrep NetworkManager [Enter]
You will get a PID number
In this example the PID number is 1112
Next Enter
kill 1112
This kills NetworkManager
Next type
pgrep wpa_supplicant [Enter]
In this example the PID number is 2221
kill 2221
This kills wpa_supplicant
You can test this by running airodump-ng
When you want to restore wireless functionality type
service NetworkManager restart
service wpa_supplicant restart
You can test for full functionality by trying to connect to a network you never associated to before.
