DWR-956 Wireless AC1200 4G LTE Router
with Gigabit Ethernet Ports and 1 FXS Port
User Manual
Configuring via Web-based Interface
Parameter Description
Enable DFS
Available on the 5 GHz tab.
Move the switch to the right to enable the DFS (Dynamic Frequency
Selection) mechanism. Upon that the router uses the channels at
which radars and other mobile or stationary radio systems can
operate, but switches to other channels if these devices require this.
In order to use the DFS mechanism, the automatic channel selection
should be enabled (on the Wi-Fi / Basic Settings page).
Move the switch to the left not to let the router use the channels at
which radars and other mobile or stationary radio systems can
operate.
Drop multicast
Move the switch to the right to disable multicasting for the router's
WLAN. Move the switch to the left to enable multicasting from the
WAN connection selected on the Advanced / IGMP page.
Enable TX
Beamforming
TX Beamforming is the signal processing/directing technique which
helps to support a high enough transfer rate in the areas with difficult
conditions for the signal propagation.
Move the switch to the right to improve the signal quality.
Adaptivity mode
Move the switch to the right to let the router switch from the
channels at which radars and other mobile or stationary radio
systems operate in case it interferes with these devices. Such a
setting can slow down the router's WLAN.
In order to use the adaptivity mode, the automatic channel selection
should be enabled (on the Wi-Fi / Basic Settings page).
Reduce power on
OFDM modulation
Available on the 5 GHz tab.
Move the switch to the right to lower service signals strength for
improving the quality of their transmission. Use the setting in case of
problems with connecting wireless clients to the router.
STBC
The STBC (Space-time block coding) technique allows increasing
data transfer reliability even for portable devices equipped with poor
antennas (smartphones, pads, etc.) due to using several data streams
and processing several versions or received data.
Move the switch to the right if you need to use the STBC technique.
