Advanced > Performance

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.

Wireless

Performance-

Displayed in this window are

the Wireless Performance

features for the Access Point

portion of the VDI-624.

TX Rates-

Auto is the default selection.

Select from the drop down

menu.

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.
