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. 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.

TX Rates-
Auto is the default selection.

SSID Broadcast- 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.
