Operating
Channel
This field displays only when you select 802.11a in the 802.11
Radio Mode field.
This is the channel currently being used by your AP.
RTS/CTS
Threshold
Use RTS/CTS to reduce data collisions on the wireless network if you
have wireless clients that are associated with the same AP but out of
range of one another. When enabled, a wireless client sends an RTS
(Request To Send) and then waits for a CTS (Clear To Send) before it
transmits. This stops wireless clients from transmitting packets at the
same time (and causing data collisions).
A wireless client sends an RTS for all packets larger than the number
(of bytes) that you enter here. Set the RTS/CTS equal to or higher
than the fragmentation threshold to turn RTS/CTS off.
Fragmentation
Threshold
The threshold (number of bytes) for the fragmentation boundary for
directed messages. It is the maximum data fragment size that can be
sent. Enter an even number between 256 and 2346.
Beacon Interval When a wirelessly networked device sends a beacon, it includes with
it a beacon interval. This specifies the time period before the device
sends the beacon again. The interval tells receiving devices on the
network how long they can wait in low-power mode before waking up
to handle the beacon. This value can be set from 30ms to 1000ms. A
high value helps save current consumption of the access point.
DTIM Delivery Traffic Indication Message (DTIM) is the time period after
which broadcast and multicast packets are transmitted to mobile
clients in the Active Power Management mode. A high DTIM value can
cause clients to lose connectivity with the network. This value can be
set from 1 to 100.
Output Power Set the output power of the NWA in this field. If there is a high
density of APs in an area, decrease the output power of the NWA to
reduce interference with other APs. Select one of the following
100%(Full Power), 50%, 25%, 12.5% or Minimum. See the
product specifications for more information on your NWA’s output
power.
Note: Reducing the output power also reduces the NWA’s
effective broadcast radius.
