Public bug reported:

After waking from a suspend my laptop (Lenovo X1 Carbon) does not always
re-connect to the wifi network. It seems to be consistent in which
networks (access points) it will connect to and which it  won't.

I cannot force it to reconnect using the applet to 'connect to hidden
network'. It says that the connection is invalid, and the 'connect'
button is greyed out.

Logout/login does not clear the condition.

After a reboot the machine connects with no problems.

There is a similar problem with *some* new wifi networks in that after
configuring the new connection I have to reboot in order to use it.
