6.3.1.7.2 RTS Threshold
(Not available in Monitor mode)
Use this parameter to control collisions on the link that can reduce throughput. If the Status >
Wireless page shows increasing values for Tx multiple retry frames or Tx single retry frames, you
should adjust this value until the errors clear up. Start with a value of 1024 and then decrease to 512
until errors are reduced or eliminated. Note that using a small value for RTS threshold can affect
throughput. Range is 128 to 1540.
If a packet is larger than the threshold, the AP will hold it and issue a request to send (RTS) message
to the client station. Only when the client station replies with a clear to send (CTS) message will the
AP send the packet. Packets smaller than the threshold are transmitted without this handshake.
6.3.1.7.3 Multicast Tx Rate
(Not available in Monitor mode)
Use this parameter to set the transmit rate for multicast traffic. This is a fixed rate, which means that
if a station is too far away to receive traffic at this rate, the multicast is not be seen by the station.
6.3.1.7.4 Antenna Selection
(Not available in Monitor mode)
Select the antenna the radio will transmit and receive on. Regardless of the antenna that is selected,
the AP can only create a single wireless cell using the radio.
„
If a single antenna is used, it can be connected to either Main or Aux.
„
When creating a point-to-point wireless bridge, it is recommended that a single directional
antenna be used on either Main or Aux.
„
For maximum wireless coverage, use two omnidirectional antennas, and select the Diversity
option.
6.3.1.7.5 Beacon Interval
(Not available in Monitor mode)
Sets the number of time units (TUs) that the AP waits between transmissions of the wireless beacon.
One TU equals 1024 microseconds. The default interval is 100 TU, which is equal to 102.4
milliseconds. Supported range is from 20 to 500 TU.
NOTE
RSSI (Received Signal Strength Indication) is the difference between the amount of noise in an
environment and the wireless signal strength. It is expressed in decibels (dB). The higher the
number the stronger the signal.
