Field Description
RTS Threshold Request to Send, when set in bytes, specifies the packet
size beyond which the WLAN Card invokes its RTS/CTS
mechanism. Packets that exceed the specified RTS
threshold trigger the RTS/CTS mechanism. The NIC
transmits smaller packet without using RTS/CTS. The
default setting of 2347 (maximum length) disables RTS
Threshold.
DTIM Interval Delivery Traffic Indication Message (DTIM) is also known
as Beacon Rate. The entry range is a value between 1
and 65535. A DTIM is a countdown variable that informs
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 default is 1.
Beacon Interval The amount of time between beacon transmissions in
milliseconds. The default is 100 ms and the acceptable
range is 1 – 65535. The beacon transmissions identify
the presence of an access point. By default, network
devices passively scan all RF channels listening for
beacons coming from access points. Before a station
enters power save mode, the station needs the beacon
interval to know when to wake up to receive the beacon
(and learn whether there are buffered frames at the
access point).
Global Max Clients The maximum number of clients that can connect to the
router.
Xpress
TM
Technology Xpress Technology is compliant with draft specifications of
two planned wireless industry standards.
Transmit Power Set the power output (by percentage) as desired.
WMM (Wi-Fi
Multimedia) The technology maintains the priority of audio, video and
voice applications in a Wi-Fi network. It allows multimedia
service get higher priority.
WMM No
Acknowledgement Refers to the acknowledge policy used at the MAC level.
Enabling no Acknowledgement can result in more efficient
throughput but higher error rates in a noisy Radio
Frequency (RF) environment.
WMM APSD This is Automatic Power Save Delivery. It saves power.
Band Steering Enable band steering for dual band traffic control if
applicable.
Enable Traffic
Scheduler Enable traffic scheduler to ensure wireless traffic is shared
based on scheduler scheme.
Airtime Fairness Enable airtime fairness for varied wireless clients.
