wifi problems on HP Pavilion dv4-1220us

[Ted]

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.
