Title:
  Dell XPS 13 9333 with Intel 7260 poor range

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  With stock 14.04 kernel, wireless gets poor range and intermittently
  cuts out / lags. Additionally, at school, I can associate with AP for
  a few minutes, then it disconnects and repeatedly fails to reconnect
  until rebooting.

  Tested kernel 3.19.0-031900 and the range issue went away, completely,
  and is acting as it should in a perfect world. (After spring break
  I'll report about the school's AP dropping me.)

  This is identical to bug 1315221, except I'm reporting 3.13.0-27 and
  the issue usually doesn't occur if I'm within 15 feet of the router.
  (Actually, it just decided to prove me wrong now.)
