Comment 4 for bug 362152

Hi,
I had the same problem and was looking for a solution. Recently I got one, perhaps it's useful for anybody.

If you want to connect to a wlan with hidden ssid, you must:
- first provide a proper connection (in a terminal use nm-connection-editor). It's necessary to enable the checkbox "available for all users".
- Then you can get the uuid of the connection with "nmcli con list system" (again in a terminal)
- Then you can edit the file /etc/rc.local (as superuser) and insert
nmcli con up uuid "give here the uuid you got before" --timeout 60
