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). 
 
*For Windows 2000/XP only 
 

WPA-NONE – 

WPA-NONE is defined for Ad hoc mode and 

behaves like WPA-PSK (WPA-PSK is only defined for 
infrastructure mode). The user manually enters the Pre-Shared 
Key (8 ~ 63 characters) in each wireless station in the network 
and WPA-NONE controls unauthorized users that don't have the 
matching Pre-Shared Key from joining the network and also 
encrypts the data traveling between authorized devices.
