Title:
  Repeateadly WiFi disconnection since upgrade to Trusty

Status in “linux” package in Ubuntu:
  New

Bug description:
  Using my laptop since a long time with Saucy with no problem, I got disconnected all the time from WiFi since upgrade to trusty.
  Laptop is a Lenovo L420 with Realtek WiFi integrated.

  What happens :
  After some time connected to WiFi, connection is lost, NM notification going from "on air" to "not connected".
  To solve the problem, I need to either bring down/up WiFi with physical switch, or uncheck/check 'Activate WiFi' in NM applet, or uncheck/check 'Activate Network' in NM applet.
