NM does not automatically reconnect to APs that disappear and reappear shortly after

[Romano Giannetti]

This is more a nuisance than a bug, but I confirmed it on two different machines.

We have a (Condo, I cannot modify it) wireless router that fails quite frequently --- the AP disappear. After a few swconds (10 to 30, average) it comes up again. All my devices (phones, tablets etc) will automatically reconnect then; my two linux laptops fails to do that.

The AP disappear from the list of available AP when it goes down, as expected, but after then it does not reappear unless I switch wireless "off" then "on" again, at which point NM reconnects correctly.

Apport info attached for the laptop running Ubuntu 13.04; the same happens in the other one with Ubuntu Gnome 13.10.
