Secton 3 - Configuraton

Tx Rate:

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.
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 2436.
If inconsistent data flow is a problem, only a minor
modification should be made.
Fragmentation: 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.

DTIM Interval:

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.
Preamble Type: 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 Function:

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.
