FON_FREE_EAP

The newly-updated FON firmware becomes to broadcast the SSID "FON_FREE_EAP", that is secured by WPA-enterprise protocole and unnecessary for the additional web-login.  This secured FON seems to be broadcasted from the fonera collaborated with SoftBank Japan (偽FON, 禿FON).  The official tutorial about FON_FREE_EAP is not disclosed as far as I know.
My setting in windows7.

 WPA-enterprise & AES

User authentication

In windows8.1, WPA-enterprise (not WPA2-enterprise) is missing from the internet connection settings.  Nevertheless, WPA-enterprise profiles can be imported using command line.  I exported this profile from windows7 machine, and imported to windows 8.1 machine (ECS LIVA).  It works fine.
