WPA Wi-Fi Protected Access (WPA) is a subset of the IEEE
802.11i standard. Key differences between WPA and
WEP are user authentication and improved data
encryption.
WPA-PSK If you don't have an external RADIUS server you should
use WPA-PSK (WPA Pre-Shared Key) that only requires
a single (identical) password entered into wireless
gateway and wireless client. As long as the passwords
match, a client will be granted access to the wireless
LAN.
WPA2 Advanced protocol, certified through Wi-Fi Alliance's
WPA2 program, implements the mandatory elements of
802.11i. In particular, it introduces a new AES-based
algorithm, CCMP, that is considered fully secure.
WPA2-PSK If you don't have an external RADIUS server you should
use WPA2-PSK (WPA Pre-Shared Key) that only requires
a single (identical) password entered into wireless
gateway and wireless client. As long as the passwords
match, a client will be granted access to the wireless
LAN.
WPA/WPA2 Encryption Switch to enable or disable WPA/WPA2 encryption.
WPA Pre-Shared Key The encryption mechanisms used for WPA and WPA-PSK
are the same. The only difference between the two is that
WPA-PSK uses a simple common password, instead of
user-specific credentials. Refer to page 4 for the default
value of the shared key.
RADIUS Server Input the IP address of RADIUS server, if used.
RADIUS Port Enter a RADIUS port number when WPA or 802.1x
network authentication is selected.
RADIUS Key Enter the RADIUS Key when WPA or 802.1x network
authentication is selected.
Group Key Rotation Interval Allows the wireless router to generate the best possible
random group key and update all the key-management
capable stations periodically.
WPA/WPA2 Re-auth Interval Wireless router (if using WPA-PSK key management) or
RADIUS server (if using WPA key management) sends a
new group key out to all clients. The re-keying process is
the WPA equivalent of automatically changing the WEP
key for a wireless access point and all stations in the
WLAN on a periodic basis. Setting of the WPA Group Key
Update Timer is also supported in WPA-PSK mode.
