Comment 27 for bug 1681513

In my logs, I see the message:
"...aborting authentication ...by local choice (Reason: 3=DEAUTH_LEAVING)"
(I've listed below the relevant portion of the log file, since the logs above do not include this particular error).

The solution posted in comment #1 (https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1681513/comments/1) worked for me...

    $ sudo nano /etc/NetworkManager/NetworkManager.conf
    # Append...
    - - - - - - - - - - - - - - - - - - - -
        [Device]
        wifi.scan-rand-mac-address=no
    - - - - - - - - - - - - - - - - - - - -
    $ sudo service network-manager restart

I did not need to install dnsmasq-base, as suggested in comment #24 (https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1681513/comments/24).
What is the purpose of installing this?
