The airmon-ng program in the aircrack suite of tools has a method of disabling NetworkManager thru the command
airmon-ng check kill
However there is no method of restoring NetworkManager functions thru airmon-ng.
Attached is a short script which restores NetworkManager functions.
Place the program in /Home/Kali/
Make the program executable thru the command
sudo chmod 755 sudo chmod 755 restorenetwork.sh
Run the program by entering
sudo ./restorenetwork.sh
or place in /root/ and run fom there
