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/MLD page. If
the switch is moved to the right, the device will not be available by
the domain name for Wi-Fi clients.
Available on the 5 GHz tab.
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.
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).
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.
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.
