Parameter Description
BG protection
Available on the 2.4GHz 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.
Short GI
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.
Drop multicast
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

Connections Setup / WAN page.
Beacon Period
The   time   interval   (in   milliseconds)   between   packets   sent   to
synchronize the wireless network.
RTS threshold
The minimum size (in bytes) of a packet for which an RTS frame is
transmitted.
Frag threshold
The maximum size (in bytes) of a non-fragmented packet. Larger
packets are fragmented (divided).
DTIM period
The time period (in seconds) between sending a DTIM (a message
notifying   on   broadcast   or   multicast   transmission)   and   data
transmission.
Station Keep Alive
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.
