Network Manager troubles after wifi password change

I recently changed my router’s password and even changed the authentication type. Now after that Network Manager started crashing. And thanks to the new GNOME 3 network manager, I was not able to manually change the password, I was not even getting where they had hidden the previous Network Connections window which used to list all the interfaces.

After googling for a while I found the command.

$ nm-connection-editor

Cheers!
