Ports, and USB Port
User Manual
Parameter
Enable DFS
Enable TX
Beamforming
STBC
B/G protection
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.
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.
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.
Available on the 2.4 GHz tab.
The 802.11b and 802.11g protection function is used to minimize
collisions between devices of your wireless network.
Select a value from the drop-down list.
Auto: The protection function is enabled and disabled
•
automatically depending on the state of the network (this
value is recommended if your wireless local area network
consists of both 802.11b and 802.11g devices).
Always On: The protection function is always enabled (this
•
setting can substantially lower the efficiency of your wireless
network).
Always Off: The protection function is always disabled.
