Move the switch to the right to let the router to automatically choose
the most suitable channel bandwidth (20MHz or 40MHz) for the
connected devices (this setting can substantially lower the data
transfer rate of your wireless network). The switch is displayed when
the 20/40 MHz value is selected from the Bandwidth drop-down
list.
The transmit power (in percentage terms) of the router.
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.
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).
