Public bug reported:
If my Thinkpad T420s using Ubuntu 14.04.3 resumes from standby, it
immediately tries to reconnect to my wifi, but is trying a long time
without success until some timeout. It retrys then, successfully.
I can stop this manually by selecting disconnect and the network
manually again, which leads to a successful connection.
dmesg states for the first unsucessful try:
[XXXXXXXXXX] wlan0: deauthenticating from XX:XX:XX:XX:XX:XX by local
choice (Reason: 3=DEAUTH_LEAVING)
This worked well on Ubtuntu 12.04. However it take a little longer delay
between wakeup and connect there if I remember right.
