Beacon Interval Set the number of milliseconds that should pass between sending out a beacon. Enter a
time period between 1 and 1000. The default is
100 .
RTS Threshold Enter a value between 0 and 2442 to enable an RTS/CTS handshake to avoid
retransmitting due to hidden nodes. The default is
2432 .
Fragmentation
Threshold Enter a value between 256 and 2446 to enable a fragmentation threshold. This sets the
maximum size of data fragments that can be sent. The default is
2432 . Use a low setting
if there is a great deal of radio interference.
DTIM Interval This setting, always a multiple of the beacon period, determines how often the beacon
contains a delivery traffic indication message (DTIM). The DTIM tells client devices that
are set to power-save that a packet is waiting for them. The DTIM Interval’s valid range is
1 to 65535.
