The table lists all configured MAC Filter entries. To delete entries, check the corresponding select boxes and then press DELETE SELECTED Wireless Settings Beacon Interval: The 802.11G ACCESS POINT broadcasts beacon frames regularly to announce its existence. The beacon Interval specifies how often beacon frames are transmitted - in time unit of miniseconds. Its default value is 100; a valid value should be between 1 and 65,535.
IEEE 802.11g Access Point User’s Guide RTS Threshold: RTS/CTS frames are used to gain control of the medium for transmission. Any unicast (data or control) frames larger than specified RTS threshold must be transmitted following the RTS/CTS handshake exchange mechanism. The RTS threshold should have a value between 256-2432 bytes, with a default of 2432. A value of zero activates the RTS/CTS handshake before every transmission. It is recommended that this value does not deviate from the default too much.
Radius Settings Radius servers provide centralized authentication services to wireless clients. Two Radius servers can be defined, one acting as a primary, the other acting as a backup. Two user authentication methods can be enabled: one based on MAC address filter, the other based on 802.1x EAP/MD5 authentication. MAC address filtering based authentication requires a MAC address filter table to be created in either the 802.11G ACCESS POINT and/or the Radius server.
