This bug is also present for me as well. I can connect to unprotected and WEP protected wireless internet connections, but when I try to connect to my school's wireless internet, which uses WPA2 enterprise security, the network settings window pops up with no options to change or configure the connections and the activity indicator will appear as in the previous comment. I have Linux Mint 17.1 Rebecca.
