LEAP was proven to be susceptible to dictionary attacks, and EAP-FAST is preferable to LEAP. In short, EAP-FAST is hardened LEAP with better crypto protecting the challenge/response mechanism.
Using EAP-FAST – Before you can enable EAP-FAST authentication, your network access point must be configured for EAP-FAST authentication. Perform one of the following from the Security Tab:
zIf you want to enable EAP-FAST without WPA/WPA2, choose 802.1x under Set Security Options and LEAP in the 802.1x EAP Type drop-down box.
zIf you want to enable EAP-FAST with WPA/WPA2, choose WPA/WPA2 under Set Security Options and LEAP in the WPA/WPA2 EAP Type drop-down box.
