LABEL 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 Router 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 Router
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 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 in Both Bands 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 in Both Bands 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.
20MHz in 2.4G Band and 40MHz in 5G Band uses a single radio channel in the 2.4 GHz
band and bonds two adjacent radio channel in the 5.0 GHz band. Use this if you have
IEEE 802.11b and/or g clients that do not support 40 MHz and IEEE 802.11n clients that
do.
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 Router
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 Router. This can
increase transmission rates, although IEEE 802.11b or IEEE 802.11g clients will not be
able to connect to the Router.
RIFS
Advertisement
Select Auto to enable the Reduced Inter-frame Spacing (RIFS) feature. It improves the
Router’s performance by reducing the amount of dead time required between OFDM
transmissions.
