I had a similar problem ubuntu 13.04. I selected Protected EAP (PEAP) for authentication mode, and ignored choosing a certificate file.

Now I am connected successfully with the following settings.

Some wireless networks use a Certificate Authority file which can be configured in the following place:

Network menu (the four spreading arcs icon) > Edit Connections... > choose your network > Network Security tab > pick "WPA & WPA2 Enterprise" from the pop-down menu > CA Certificate.

(My own use for a CA file is a VPN that requires me to install a CA in my browser. That doesn't seem to be your case.)

I used the AddTrust_External_Root found in the mozilla certificates - /usr/share/ca-certificates/mozilla/

Wifi worked.
