Description
Beacon Interval
The default value is 100. The Beacon Interval value indicates the
frequency interval of the beacon. A beacon is a packet broadcast by
the AP to synchronize the wireless network. 50 is recommended in
poor reception.
DTIM Interval
The default value is 1. This value, between 1 and 255 milliseconds,
indicates the interval of the Delivery Traffic Indication Message (DTIM).
A DTIM field is a countdown field informing clients of the next window
for listening to broadcast and multicast messages. When the AP has
buffered broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. Its clients hear the
beacons and awaken to receive the broadcast and multicast
messages.
Fragmentation
Threshold
This value should remain at its default setting of 2346. The range is
256-2346 bytes. It specifies the maximum size for a packet before
data is fragmented into multiple packets. If you experience a high
packet error rate, you may slightly increase the Fragmentation
Threshold. Setting the Fragmentation Threshold too low may result in
poor network performance. Only minor modifications of this value are
recommended.
RTS Threshold
This value should remain at its default setting of 2347. The range is
0-2347 bytes. Should you encounter inconsistent data flow, only
minor modifications are recommended. If a network packet is smaller
