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.

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.

packets are fragmented (divided).
The time period (in beacon frames) between sending a DTIM (a
message notifying on broadcast or multicast transmission) and data
