Guard interval (in nanoseconds). This parameter defines the interval
between symbols transmitted when the router is communicating to
wireless devices.
Enable: the router uses the 400 ns short guard interval. Only for the
wireless network operating modes which support 802.11n and
802.11ac standards (see the value of the Wireless mode drop-
down list on the Wi-Fi / Basic Settings page).
Disable: the router uses the 800 ns standard guard interval.
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.
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 time interval (in milliseconds) between packets sent to
synchronize the wireless network.
The minimum size (in bytes) of a packet for which an RTS frame is
transmitted.
The maximum size (in bytes) of a non-fragmented packet. Larger
packets are fragmented (divided).
The number of beacon frames between sending DTIM messages
(messages notifying on broadcast or multicast transmission).
The time interval (in seconds) between keep alive checks of wireless
devices from your WLAN. When the value 0 is specified, the
checking is disabled.
