LABEL DESCRIPTION
RTS/CTS
Threshold Data with its frame size larger than this value will perform the RTS
(Request To Send)/CTS (Clear To Send) handshake.
Enter a value between 256 and 2346.
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.
Intra-BSS
Traffic A Basic Service Set (BSS) exists when all communications between
wireless clients or between a wireless client and a wired network client go
through one access point (AP).
Intra-BSS traffic is traffic between wireless clients in the BSS. When
Intra-BSS is enabled, wireless clients can access the wired network and
communicate with each other. When Intra-BSS is disabled, wireless
clients can still access the wired network but cannot communicate with
each other.
Output Power Set the output power of the NVG2053 in this field. If there is a high
density of APs in an area, decrease the output power of the NVG2053 to
reduce interference with other APs. Select one of the following 100%,
90%, 75%, 50% or 25%. See the product specifications for more
information on your NVG2053’s output power.
HT (High Throughput) Physical Mode - Use the fields below to configure the 802.11
wireless environment of your NVG2053.
Operating
Mode
Choose this according to the wireless mode(s) used in your network.
Mixed - Select this if the wireless clients in your network use different
wireless modes (for example, IEEE 802.11b/g and IEEE 802.1n modes)
Green - Select this if the wireless clients in your network uses only one
type of wireless mode (for example, IEEEE 802.11 n only)
Channel
Bandwidth Select the channel bandwidth you want to use for your wireless network.
It is recommended that you select 20/40 (20/40 MHz).
Select 20 MHz if you want to lessen radio interference with other wireless
devices in your neighborhood.
Guard Interval Select Auto to increase data throughput. However, this may make data
transfer more prone to errors.
Select Long to prioritize data integrity. This may be because your
wireless network is busy and congested or the NVG2053 is located in an
environment prone to radio interference.
