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
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.
