Did not disect to the bottom - released version 3.16.0-28 corrects the
problem, so I assume that someone beat me to it.
Fixed and verified over the last few days by switching back and forth
between -25 and -28. Wifi keeps dropping in -25, and stays stable
overnight in -28.
** Changed in: linux (Ubuntu)

Title:
[Dell Latitude E7440] Wifi keeps dropping with Intel Wireless 7260
Status in linux package in Ubuntu:
Fix Released
Bug description:
After the connection is dropped, a hardware switch disconnect/connect is
necessary to re-establish connection, the connection does not automatically
reappear. The problematic line in the dmesg output is:
wlan0: deauthenticated from 00:16:b6:01:69:74 (Reason:
7=CLASS3_FRAME_FROM_NONASSOC_STA)
The frequency of the problem drops considerably moving to a less congested
channel, but it still happens - I am stationary at about 3 meters from the
access point. Other devices (Android phones, iPad, other laptops) are
connecting to the same access point with no problems at all.
