„Maximum Multicast Data Rate—Select the appropriate maximum broadcast/multicast data rate for your network. Setting a low multicast data rate helps to ensure that data can reach all client stations. Setting a high data rate can improve performance for high-bandwidth multicast applications (for example, multimedia streaming service).

„Beacon Interval (20-1000)—Sets the beacon signal interval at which beacon frames are transmitted from the access point. The beacon signals allow wireless devices to maintain contact with each other. They may also carry power-management information. The Beacon Interval unit is TU, which corresponds to 1024 microseconds. (Default: 100 TU)

„Data Beacon Rate (DTIM) (1-255)—Determines how often the beacon signal contains a delivery traffic indication message(DTIM). This tells client devices that are in power-saving mode that a packet is waiting for them.

„Fragment Length (256-2346) (802.11g only)—The Fragment Length can be set between 256 and 2,346. If the packet size is smaller than the preset fragment size, the packet will not be segmented.

Fragmentation of the PDUs (Package Data Unit) can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size. If there is significant interference present, or collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will speed up the retransmission of smaller frames. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames. (Default: 2346)

„RTS Threshold (0-2347)—Set the RTS (Request to Send) frame length. You may configure the access point to initiate an RTS frame sequence always, never, or only on frames longer than a specified length. If the packet size is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled.

The access point sends RTS frames to a particular receiving station to negotiate the sending of a data frame. After receiving an RTS frame, the station sends a CTS (Clear to Send) frame to acknowledge the right of the sending station to send data frames.

The access points contending for the medium may not be aware of each other. The RTS/CTS mechanism can solve this hidden node problem. (Default: 2346)

„Preamble Length (802.11g and 802.11b only)—IEEE 802.11 frames begin with an alternating pattern of 1s and 0s called the preamble, which tells receiving stations that a frame is arriving. This provides time for the receiving station to synchronize to the incoming data stream. Enabling the Short preamble can boost your throughput; however, this can cause interoperability issues. (Default: Long)
