Bug Description

Upgraded from 14.04 to 14.10. Before Wifi would reconnect after waking up from sleep mode. After Update reconnect fails with wlan0: aborting authentication with 1c:c6:3c:95:e7:74 by local choice (Reason: 3=DEAUTH_LEAVING).

I worked around this by killing wpa_supplicant with a script in /etc/pm/sleep.d

#!/bin/sh

case "$1" in
        thaw|resume)
                { killall wpa_supplicant ; } 2>/dev/null
                ;;
        *)
                ;;
esac

exit $?

Similiar error message to my bug: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1408963

Perhaps dupicate? Although, this bug is triggered by suspend, while mine shows up randomly.

I have the same symptoms after upgrade from 14.10 to 15.04.

I'm attaching my ubuntu-bug output, but I can file a new bug if this is adjudged a different issue.

I have this problem in Ubuntu 14.04 LTS Trusty Thar. I have a Lenovo W510 laptop. Could it be that this problem occurs with only a certain type of hardware? After all, not everybody using Ubuntu has this problem.

My hardware is: 03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 35)

As not everybody experiences this issue:
Is the issue related to the WLAN network being HIDDEN/VISIBLE?

There are so many open bugs on network-manager, wifi and resume that it's difficult to find the right one to comment on. Anyway, trying e.g. this one. Can the people having this problem comment on whether there is Docker installed on their system?

I am specifically asking this question because a colleague of mine claimed not have any problems with WiFi in Ubuntu but since he installed Docker, the WiFi became so unusable that he was forced to use wired connection. On my system network manager never worked good (being it 14.04 or 16.04) but I cannot comment on Docker as it was installed from the very beginning.
