Title:
  8086:08b1 (rev 6b) [Dell XPS 13 9333] iwlwifi regularly loses
  connection/becomes unusable on Intel 7260

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  My Intel 7260 network card regularly shows very poor performance
  and/or loses its connection entirely. On several occasions I have been
  unable to reestablish an association with the AP without rebooting.
  This occurs even if the laptop is within a few feet of the AP. I did
  not have this problem on 12.04 with a quantal backport kernel.

  Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev 6b)
  Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:c470]
