After upgrading to 15.04 today from 14.10 the 'Connect' button for wireless network connections will always show as disabled. Therefore I cannot click or press enter to attempt to connect to a network. The same thing goes for the 'Save' button on the Edit Connections screen as well.
Everything worked fine in 14.10. Anyone else experiencing this issue following the upgrade?

I would like to add, that I was having the same issue and the resolution was checking "no CA certificate required" for a WPA2 Enterprise connection
