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.

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

for listening to broadcast and multicast messages. The default

interval is 3.
