Title:
  [Lenovo ThinkPad X1 Carbon 20A8] Networking dies

Status in linux package in Ubuntu:
  Expired

Bug description:
  I have a fresh install of 14.04 lts on a Lenovo X1 Carbon v2.  I've
  noticed that the wireless network connection will drop and I have to
  disable and reenable networking to get it to work again.

  It's occurring to me now that this could be a problem with
  NetowrkManager rather than the kernel.

  Please let me know how I can help debug.  Thanks!
