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: 20-1000 TUs; Default: 100 TUs)
◆ 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)
