sorry for late reply.
Do you use dual boot with windows, or ubuntu is the only system....
As I have a dual boot system with windows and xubuntu now, the same thing happens to me (checks password for long and doesn't connect) when I go to windows and return to xubuntu.
I have worked around it be simply shutting down xubuntu once and starting again. Reboot porabably don't work.
Had the same problem with Linux Mint 17 cinnamon and Linux Mint 17 XFCE too...
