Public bug reported:
It started a few weeks ago when network-manager started to lose connection
randomly. Before these few weeks it sometimes happened after wake-up from
suspend, but now I don't even have to suspend to experience this issue. It just
suddenly seem to lose the signal of my home wi-fi network and I can only
reconnect it after restarting network manager. I'm almost sure about not having
problem with the router because after losing signal I can still see my
printer's hotspot, and if I connect it after a few minutes that connection
breaks too.
In the first weeks of my fresh ubuntu 14.04 install this issue didn't happen
(only a few times after wakeup as I've mentioned, but).
