Title:
  Wifi (wlan) slow and unstable when updated to 14.04

Status in “network-manager” package in Ubuntu:
  Confirmed

Bug description:
  Since I updated ubuntu to 14.04 version, my wifi is unstable and slow.
  I did wifi tests and sometimes the connection stabilze but in some
  minutes (sometimes 30minutes, or 8minutes, or more, or less) the wifi
  network disconnects. I need to turn the wireless adapter off and on
  again to reconnect.

  When I tested my wifi speed (in some websites that measure this), I
  see that the download proccess is very unstable. Sometimes go to the
  maximum speed and after stops, and go slow, and go fast... very
  unstable!

  I dont know if this is a network problem or kernel problem, but I can
  confirm that this just happens on new ubuntu version (14.04) - I have
  other notebook with other distro and works fine, and my Android device
  has a stable wifi connection.
