impossible to reconnect to hidden network on ubuntu 16.04 beta2

[Fabio C. Barrionuevo]

after set up to connect to a hidden wireless network in ubuntu connects normally.

the problem happens after restart Ubuntu.

Ubuntu 16.04 beta 2 does not automatically connect the hidden network previously set and also not let me connect manually (see screenshot)

I have Ubuntu 14.04 installed on the same machine, and everything works correctly.

Please call me if you need additional information.
