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.
•
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 Settings /
Wireless Network page).
Disable: the router uses the 800 ns standard guard interval.
•
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).
