The following items are displayed on this page:
◆Fragment Threshold — Configures the minimum packet size that can be fragmented when passing through the wireless interface. Fragmentation of the PDUs (Package Data Unit) can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size. If there is significant interference present, or collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will speed up the retransmission of smaller frames. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames. (Range: 256- 2346 bytes; Default: 2346 bytes)
◆RTS Threshold — Sets the packet size threshold at which a Request to Send (RTS) signal must be sent to a receiving station prior to the sending station starting communications. The wireless interface sends RTS frames to a receiving station to negotiate the sending of a data frame. After receiving an RTS frame, the station sends a CTS (clear to send) frame to notify the sending station that it can start sending data.
◆Beacon Interval — The rate at which beacon signals are transmitted from the wireless interface. The beacon signals allow wireless clients to maintain contact with the ADSL Router. They may also carry power- management information. (Range:
◆Data Rate — The maximum data rate at which the wireless interface transmits multicast and broadcast packets. (Options: Auto, 1, 2, 5.5, 11, 6, 9, 18, 24, 36, 48, 54 Mbps; Default: Auto)
