￿Beacon Period: Beacons are packets sent by a wireless router to synchronize wireless devices. Specify a Beacon Period value between 20 and 1000. The default value is set to 100 milliseconds. Values that are not a multiple of 4, are forced to a multiple of 4.

￿RTS Threshold: When an excessive number of wireless packet collisions are occurring, wireless performance can be improved by using the RTS/CTS (Request to Send/Clear to Send) handshake protocol. The wireless transmitter will begin to send RTS frames (and wait for CTS) when data frame size in bytes is greater than the RTS Threshold. This setting should remain at its default value of 2346 bytes.

￿Fragment Threshold: Wireless frames can be divided into smaller units (fragments) to improve performance in the presence of RF interference and at the limits of RF coverage. Fragmentation will occur when frame size in bytes is greater than the Fragmentation Threshold. This setting should remain at its default value of 2346 bytes. Setting the Fragmentation value too low may result in poor performance.

￿DTIM Interval: A Delivery Traffic Indication Message informs all wireless clients that the access point will be sending Multi-cast data.

￿Wireless Client Isolation: Enabling Wireless Client Isolation (also known as L2 Isolation) prevents associated wireless clients from communicating directly with each other by using low-level (link layer) protocols and without passing through the router.

￿Multicast to Unicast: When multiple wireless clients are receiving streaming media, enabling this option can provide better performance in some cases by transforming each multicast packet into multiple unicast packets. (Broadcast packets are still sent out as broadcast packets.) If you experience interoperability problems when the AP is sending streaming media to some legacy wireless clients, try turning this option off.

￿WMM Enable: Enabling WMM can help control latency and jitter when transmitting multimedia content over a wireless connection.

￿A-MPDU Aggregation: Aggregation of wireless packets based on MAC protocol data units is a technique for maximizing performance. This option should normally remain enabled.

￿Short GI: Using a short (400ns) guard interval can increase throughput. However, it can also increase error rate in some installations, due to increased sensitivity to radio-frequency reflections. Select the option that works best for your installation.

￿EV-MAC:Enable EV-MAC option for superior experience of wireless video streaming.

￿WDS Enable: Specifies one-half of the WDS link. The other AP must also have the MAC address of this AP to create

the WDS link back to this AP. Enter a MAC address for each of the other APs that you want to connect with WDS.
