Preamble Type-
Select Short or Long Preamble. The Preamble defines the
length of the CRC block (Cyclic Redundancy Check is a com-
mon technique for detecting data transmission errors) for com-
munication between the wireless router and the roaming wire-
less network adapters. Auto is the default setting. Note: High
network traffic areas should use the shorter preamble type.
Beacon Interval-
Beacons are packets sent by an Access Point to synchronize a
wireless network. Specify a value. 100 is the default setting and
is recommended.
RTS Threshold-
This value should remain at its default setting of 2432. If inconsis-
tent data flow is a problem, only a minor modification should be
made.
Fragmentation-
The fragmentation threshold, which is specified in bytes, deter-
mines whether packets will be fragmented. Packets exceeding
the 2346 byte setting will be fragmented before transmission.
2346 is the default setting.
DTIM interval-
(Delivery Traffic Indication Message) 3 is the default setting. A
DTIM is a countdown informing clients of the next window for
listening to broadcast and multicast messages.
