Field Name Description
Beacon Interval Displays the time interval that the WAP uses to
announce itself to remote devices. The Beacon Interval
should be left at 100ms for compliance with most client
cards. The Beacon Interval specifies how often packets
are sent by the Access Point (AP) to synchronize a
wireless network and its clients
DTIM Interval Displays the time interval between
Broadcasts/Multicast transmissions. The DTIM
(Delivery Traffic Indication Message) Interval is a
countdown informing the wireless 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. AP clients hear
the beacons and awaken to receive the broadcast and
multicast messages. The DTIM Interval should be left
at 3 ms for compliance with most client cards
Fragmentation
Threshold
Allows you to set the fragmentation threshold. This
threshold should be set equivalent to the maximum
Ethernet frame size allowable on the link including
overhead (1536 bytes). Lesser settings can damage data
throughput as large frames could be fragmented or
collisions could occur. The factory default is 2346
RTS Threshold Determines at what packet size beyond which the
ready to send/clear to send (RTS/CTS) mechanism is
invoked. The factory default is 2347
