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

This setting does not affect the ability of the client to associate with

Beacon Interval—The interval between the transmission of beacon frames.
The WAP device transmits these frames at regular intervals to announce the
existence of the wireless network. The default behavior is to send a beacon
frame once every 100 milliseconds (or 10 per second). Enter an integer from
20 to 2000 milliseconds. The default is 100 milliseconds.

integer from 1 to 255 beacons. The default is 2 beacons.
The DTIM message is an element included in some beacon frames. It
indicates which client stations, currently sleeping in low-power mode, have
data buffered on the WAP device awaiting pickup.

The DTIM period that you specify indicates how often the clients served by
this WAP device should check for buffered data still on the WAP device
awaiting pickup.
this WAP device should check for buffered data still on the WAP device
awaiting pickup.
The measurement is in beacons. For example, if you set it to 1, the clients
check for buffered data on the WAP device at every beacon. If you set it to
10, the clients check on every 10th beacon.

Fragmentation Threshold—The frame size threshold in bytes. The valid
integer must be even and in the range of 256 to 2346. The default is 2346.
integer must be even and in the range of 256 to 2346. The default is 2346.
The fragmentation threshold is a way of limiting the size of packets (frames)
transmitted over the network. If a packet exceeds the fragmentation
threshold that you set, the fragmentation function is activated and the packet
is sent as multiple 802.11 frames.
transmitted over the network. If a packet exceeds the fragmentation
threshold that you set, the fragmentation function is activated and the packet
is sent as multiple 802.11 frames.
If the packet being transmitted is equal to or less than the threshold, the
fragmentation is not used. Setting the threshold to the largest value (2,346
bytes, which is the default) effectively disables the fragmentation.
