available for
WPA2 Enterprise mode.
Pre-Authentication - Enables a station to authenticate to multiple
APs for roaming securer and faster. With the pre-authentication
procedure defined in IEEE 802.11i specification, the
pre-four-way-handshake can reduce handoff delay perceivable by a
mobile node. It makes roaming faster and more secure. (Only valid in
WPA2)
