Advanced Wireless Settings

Select the basic transfer rates based on the speed

of wireless adapters on your wireless network. It is

strongly recommended to keep this setting to

Auto

.

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 2436.

If inconsistent data flow is a problem, only a minor

modification should be made.

The fragmentation threshold, which is specified in

bytes, determines whether packets will be fragmented.

Packets exceeding the 2346 byte setting will be

fragmented before transmission. 2346 is the default

setting.

A DTIM (Delivery Traffic Indication Message) is a countdown informing clients of the next window for listening to broadcast

and multicast messages. 1 is the default setting.

Select

Short

or

Long

Preamble. The Preamble defines the length of the CRC block (Cyclic Redundancy Check is a common

technique for detecting data transmission errors) for communication between the wireless router and the roaming wireless

network adapters. Long is the default setting.

Note:

High network traffic areas should use the shorter preamble type.

WMM (Wi-Fi Multimedia) provides QoS (Quality of Service) for your wireless network. Enable this option to improve the quality

of video and voice applications for your wireless clients.
