Public bug reported:
Ubuntu: 17.04
Wifi Chipset: Intel 7260 rev bb
Driver: iwlwifi 4.10.0-19-generic
If I lock my screen overnight, the following morning my Wifi will be
disconnected and is slow to reconnect and often requires multiple
connection attempts. Locking my screen for a short period of time
(minutes or hours) doesn't trigger the behavior.
Dmesg:

There are hundreds of lines like this. It looks like it gets into a loop
where it disconnects every 5 seconds. Once I log in and reconnect using
the applet in the menu bar, the connection is pretty reliable for hours
-- I generally work a full day without wifi dropping.
