Parameter	Description
Authentication Type	LEAP – LEAP is a pre-EAP, Cisco-proprietary protocol, with many
	of the features of EAP protocols. Cisco controls the ability of other
	vendors to implement this protocol, so it should be selected for
	use only when limited vendor choice for client, access-point, and
	server products is not a concern. When you have set up LEAP
	authentication, you have to enter the user name and password of
	your computer.
	WPA – WPA provides a scheme of mutual authentication using
	either IEEE 802.1x/Extensible Authentication Protocol (EAP)
	authentication or pre-shared key (PSK) technology. It provides a
	high level of assurance to enterprises, small businesses and
	home users that data will remain protected and that only
	authorized users may access their networks. For enterprises that
	have already deployed IEEE 802.1x authentication, WPA offers
	the advantage of leveraging existing authentication databases
	and infrastructure.
	WPA-PSK– It is a special mode designed for home and small
	business users who do not have access to network authentication
	servers. In this mode, known as Pre-Shared Key, the user
	manually enters the starting password in their access point or
	gateway, as well as in each wireless stations in the network.
	WPA-PSK takes over automatically from that point, keeping
	unauthorized users that don't have the matching password from
	joining the network, while encrypting the data traveling between
	authorized devices.
	WPA2 – Like WPA, WPA2 supports IEEE 802.1x/EAP
	authentication or PSK technology. It also includes a new
	advanced encryption mechanism using the Advanced Encryption
	Standard (AES). AES is required to the corporate user or
	government users. The difference between WPA and WPA2 is that
	WPA2 provides data encryption via the AES. In contrast, WPA
	uses Temporal Key Integrity Protocol (TKIP).
	WPA2-PSK – WPA2-PSK is also for home and small business.
	The difference between WPA-PSK and WPA2-PSK is that
	WPA2-PSK provides data encryption via the AES. In contrast,
	WPA-PSK uses Temporal Key Integrity Protocol (TKIP).
802.1x Setting	When you have set the Authentication Type to Open, Shared,
	WPA or WPA2, you can also enable IEEE 802.1x setting to use
	the authentication server or certification server to authenticate
	client users.
