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. This causes more overhead on every transmission, which will impact performance. However, there is no impact on performance if there are no legacy devices 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. The 802.11 protection feature is also available when the mode is 802.11b/g.
