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 standard
(see the value of the Wireless mode drop-down list on the Wi-Fi /
Basic Settings page).

packets are fragmented (divided).
The time period (in seconds) between sending a DTIM (a message
notifying on broadcast or multicast transmission) and data
transmission.
The time interval (in seconds) between keep alive checks of wireless
devices from your WLAN. When the value 0 is specified, the
