WPA, WPA2, WPA-AUTO
Wi-Fi Protected Access (WPA) introduces the Temporal Key Integrity Protocol (TKIP)
that provides added security. WPA2 adds full support for 802.11i standard and the
CCMP (AES Encryption). The WPA-AUTO tries to authenticate wireless clients using
WPA or WPA2. All 3 requires a RADIUS server available in order to do authentication
(same as 802.1x), thus there is no shared key required.
 Encryption Type: There are two encryption types TKIP and CCMP (AES). While
CCMP provides better security than TKIP, some wireless client stations may not be
equipped with the hardware to support it. You can select Both to allow TKIP clients
and CCMP clients to connect to the Access Point at the same time.
 Group Rekey Interval: A group key is used for multicast/broadcast data, and the
re-key interval is time period that the system will change the group key periodically.
The shorter the interval is, the better the security is. The default is 300 sec.
WPA-PSK, WPA2-PSK, WPA-PSK-Auto
Wi-Fi Protected Access (WPA) with Pre-Shared Key (PSK) provides better security than
WEP keys. It does not require a RADIUS server in order to provide association
authentication, but you do have to enter a shared key for the authentication purpose.
The encryption key is generated automatically and dynamically. WPA2-PSK adds
CCMP and AES encryption for even better security. WPA-PSK-AUTO tries to
authenticate wireless clients using WPA-PSK or WPA2-PSK.
