For MTeams persistent usb i386 install of Kali 2016.1R the use of the airmon-ng check kill command is no longer required. Note the usb was updated fully just prior to these tests
MTeams did the following with two(2) wifi devices wlano and eth1.
With eth1 associated to a network MTeams evoked the following commands
airmon-ng start wlan0 [Enter]
wlan0mon was produced
Then airodump-ng was run
airodump-ng wlan0mon [Enter]
There was a temporary Stoc error message which then disappeared and airodump-ng then ran after about two second delay only.
MTeams then typed
apt-get update and began processing data thru Network-Manager on eth1 while airodump-ng was running thru wlan0mon
We are asking other users to duplicate these finding
Note when we did kill Network manager we were unable to restore its function except thru a reboot.
We suspect now that multiple monitors thru iw commands is possible but that will require further tests.
