B/G protection
Available on the

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
