From time to time, when I resume from
suspend my computer, the networking won't work (happens on my laptop too, both running 14.04).
The wireless icon located in the corner looks like networking unable, and when I click on it, I get a very limited options menu.
One of the options is 'enable networking' but when I click on it, nothing happens (although it is checked).
I saw in other questions that the wireless-network card turns of when suspending and maybe it just won't turn on.. If this is the case, how to turn it on?
