Title:
  Wireless network disconnections on Dell XPS 13

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Trusty:
  Fix Released
Status in “linux” source package in Utopic:
  Fix Released

Bug description:
  SRU Justification

  Impact: Many users with Intel 7260 wireless are seeing relatively
  frequent disconnections as a result of the firmware reporting loss of
  beacons from the access point.

  Fix: Two upstream backports, one which waits for several lost beacon
  reports before reporting beacon loss to mac80211, and another which
  fixes a bug with mac80211's handling of beacon loss reports from some
  drivers (in particular iwlwifi).

  Test Case: Tested on LP#1349572.

  Regression Potential: These patches were merged upstream in 3.14 and
  3.15 without any reported regressions.

  ---

  With kernel 3.13.0.30 and 22.1.7.0, there are lots of wireless disconnections.
  Tested also with kernel 3.13.0.32 and 22.24.8.0 , also lots of wireles disconnections.

  The AP is an ASL-26555 from Movistar(Spain). Firmware version:
  v2.0.0.51B_ESv6

  Seems that when the computer is working for some time it is more easy
  to reproduce this beahviour.

  Added this bug as sugested in #1293569, comment #91.
