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.
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 in the IGMP section on the
Connections Setup / WAN 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 prevent your wireless network from
interfering with radars and other mobile or stationary radio systems.
Such a setting can slow down the router's WLAN.
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).
