Public bug reported:

Hi I am using Xubuntu 14.04.1 with the wifi card (Intel® Dual Band
Wireless-AC 7260). I have the problem with the unstable wifi connection
(wpa2, 2.4GHz) which appears in kernels > 3.0.13-40. ie 3.0.13.40 works
well while all the later kernels until the actual 13.0.13.44 suffers
with the connection problem.

1. lsb_release -rd:
Description:	Ubuntu 14.04.1 LTS
Release:	14.04

2. linux-image-3.13.0-44-generic

3. Keep stable wifi connection

4. Connection speed drops and time to time disconnects
