http://blogs.msdn.com/b/eapteam/archive/2008/10/17/how-can-i-download-the-ecp-methods-from-the-web.aspx

however I dont know if it is needed, but on my computer I already have LEAP EAPFAST and cisco PEAP

From intel, EAP-SIM, EAP-TTLS and EAP-AKA

Im running Windows 7 ultimate

I can see these options on WZC when I am setting up the security options on the profile.

I recently downloaded the wireless drivers for my Intel 3945ABG wireless card. So I cant really explain if there were since the begining or thru a windows update or maybe due to the manually updated Intel drivers...

Hope it helps you
