Title:
  wifi problems on HP Pavilion dv4-1220us

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  There are 2 bugs:

  bug 1:
  Installation of Ubuntu 16.04 fails to install and properly setup wifi on this laptop.  I had to do the following to get this to work:

  1) Plug in ethernet cable to ethernet port and turn on ethernet interface
  2) Issue command  sudo apt-get update
  3) issue command apt-get install bcmwl-kernel-source

  Until that was done the wifi switch on the laptop stayed orange (it is
  not a mechanical contact switch it is a touch switch)

  bug2:
  Once it is running and working the light on the wifi goes blue - however, touching the switch once turns off wifi and makes the light go orange - touching the switch again makes it go blue again - but  wifi does not turn back on.
