Specify a value for the beacon interval. Beacons are packets

sent by an Access Point to synchronize a wireless network. 100

is the default setting and is recommended.

Set the transmit power of the antennas.

This value should remain at its default setting of 2347. If

inconsistent data ³ow is a problem, only a minor modi²cation

should be made.

The fragmentation threshold, which is speci²ed in bytes,

determines whether packets will be fragmented. Packets

exceeding the 2346 byte setting will be fragmented before

transmission. 2346 is the default setting.

Set the interval for DTIM. A Delivery Tra´c Indication Message

(DTIM) is a countdown informing clients of the next window

for listening to broadcast and multicast messages. The default

interval is 3.

WMM (Wi-Fi Multimedia) is a QoS (Quality of Service) system

for your wireless network. Enable this option to improve

the quality of video and voice applications for your wireless

clients.
