My Wireless Network is not listed [hidden network]
Firstly I should warn you hidden wireless network has proved to be even more vulnerable than normal wireless connection and the manual evaluation is there for a reason. Hence I suggest you should reconfigure your router to be not hidden.
Of course there is a workaround to avoid the annoying manual evaluation in case you insist using hidden connection. Just open nm-connection-editor and clear the check box on 'Available to all users'. Then network-manager should be able to auto connect.
