Advanced Encryption Standard (AES).
f. Group Key Update Interval: Defines the time interval in seconds for
updating a group key.
g. Inter Client Privacy: select the check box to prevent communication
between the wireless network clients using the same access point. Clients
will not be able to view and access each other's shared directories.
• WPA and WPA2: WPA and WPA2 is a mixed data encryption method. For a
description of these fields, see WPA and WPA2 above.
• 802.1x WEP: data encryption method utilizing an automatically defined key for
wireless clients that use 802.1x for authentication and WEP for encryption.
