Protection: The protection feature contains rules to guarantee that 802.11
transmissions do not cause interference with legacy stations or applications.
By default, these protection mechanisms are enabled (Auto). With protection
enabled, protection mechanisms will be invoked if legacy devices are within
range of the AP. You can disable (Off) these protection mechanisms; however,
when 802.11n protection is off, legacy clients or APs within range can be
affected by 802.11n transmissions. 802.11 protection is also available when
the mode is 802.11b/g. When protection is enabled in this mode, it protects
802.11b clients and APs from 802.11g transmissions.
