DESCRIPTION
Band
Select
an operating band to use.
Channel
Select an operating channel to use. The choices depend on your particular region. Either
select a channel or use
Auto
to have the GPON Device automatically determine a
channel to use. If you are having problems with wireless interference, changing the
channel may help. Try to use a channel that is as many channels away from any channels
used by neighboring APs as possible.
Auto Channel
Timer
If you set the channel to
Auto
, specify the interval in minutes for how often the GPON
Device scans for the best channel. Enter 0 to disable the periodical scan.
802.11n/EWC
Select whether to enable (
Auto
) or disable (
Disabled
) the use of the wireless IEEE
802.11n modes defined by the Enhanced Wireless Consortium (EWC). These modes can
enhance speeds although the wireless clients must also support the EWC modes.
Bandwidth
20MHz
uses a single radio channel in the 2.4 GHz band and a single radio channel in the
5.0 GHz band. Use this if the wireless clients do not support channel bonding.
40MHz
bonds two adjacent radio channels in the 2.4 GHz band and two adjacent radio
channels in the 5.0 GHz band.
40MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. The wireless clients must also support 40 MHz. It is often better to use the
20 MHz setting in a location where the environment hinders the wireless signal.
Control Sideband
This is available for some regions when you select a specific channel and set the
Bandwidth
field to
40MHz in Both Bands
. Set whether the control channel (set in the
Channel
field) should be in the
Lower
or
Upper
range of channel bands.
802.11n Rate
Select a fixed transmission rate or select
Auto
to have the system configure it
automatically.
802.11n Protection Enable this feature to help prevent collisions in mixed-mode networks (networks with
both IEEE 802.11n and IEEE 802.11g traffic).
Select
Auto
to have the wireless devices transmit data after a RTS/CTS handshake. This
helps improve IEEE 802.11n performance.
Select
Off
to disable IEEE 802.11n protection. The transmission rate of your GPON
Device might be reduced in a mixed-mode network.
Support 802.11n
Client Only
Select this to only allow IEEE 802.11n wireless clients to connect to the GPON Device.
This can increase transmission rates, although IEEE 802.11b or IEEE 802.11g clients will
not be able to connect to the GPON Device.
RIFS
Advertisement
Select
Auto
to enable the Reduced Inter-frame Spacing (RIFS) feature. It improves the
GPON Device’s performance by reducing the amount of dead time required between
OFDM transmissions.
OBSS Co-
Existance
Select
Enable
to allow coexistence between 20 MHZ and 40 MHZ Overlapping Basic
Service Sets (OBSS) in wireless local area networks.
RX Chain Power
Save
Select
Enable
to activate the RX chain power save feature. It turns off one of the
Receive chains to save power.
RX Chain Power
Save Quiet Time
Specify the number of seconds the traffic must be below the PPS value before the Rx
Chain Power Save feature is activated.
RX Chain Power
Save PPS
Specify the maximum number of packets per second that can be processed by the WLAN
interface for a time period (specified in the
RX Chain Power Save Quiet Time
field)
before the Rx Chain Power Save feature is activated.
54g™ Rate
This field is available when
802.11n/EWC
is set to
Disabled
.
Select a fixed wireless transmission rate or let the GPON Device and the wireless client
automatically select a rate.
