A tooltip in this dialog says that the connection is invalid (either password or connection) on the connect button.
History: I have booted from a 16.04.1 LTS Live CD and tried to connect to WLAN in order to save some data before installing. In my case I typed a wrong password (due to wrong keybord layout). Then the network-manager asked me to enter the password again (I corrected it, but it was actually not saved despite of clicking on save -> this is a second bug?) Problem: Manually connecting to a hidden network brings up the dialog, but the dialog does not allow me to edit the password and editing in the connection view and trying again as suggested by the tooltip does not enable the connect button in this dialog. Thus I was able to view and correct the password in the connection dialog, but I am still unable to connect. even trying a "/etc/init.d/network-manager restart" at the command line didn't connect to WLAN. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-applet in Ubuntu. https://bugs.launchpad.net/bugs/1542733 Title: Connect to Hidden Wi-Fi Network, "Connect" grayed out Status in Network Manager Applet: Confirmed Status in network-manager-applet package in Ubuntu: Confirmed Bug description: Reproduce: 1.
