Beacons are packets sent by an Access Point to synchronize a
wireless network. Specify a value. 100 is the default setting and
is recommended.
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.
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.
(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.
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. Note: High network traffic areas should
use the shorter preamble type.
Choose Enabled to broadcast the SSID across the network.
All devices on a network must share the same SSID (Service
Set Identifier) to establish communication. Choose Disabled
if you do not wish to broadcast the SSID over the network.
