Advanced Wireless Router Settings
The Wireless Advanced Options settings are intended for administrator
•RTS Threshold (Default: 2346). The Request to Send Threshold is the packet size that determines if the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) mechanism or the CSMA/CA mechanism should be used for packet transmission. With the CSMA/CD transmission mechanism, the transmitting station sends out the actual packet as soon as it has waited for the silence period. With the CSMA/CA transmission mechanism, the transmitting station sends out an RTS packet to the receiving station, and waits for the receiving station to send back a CTS (Clear to Send) packet before sending the actual packet data.
•Fragmentation Length (Default: 2346). This is the maximum packet size used for fragmentation. Packets larger than the size programmed in this field will be fragmented. The Fragment Threshold value must be larger than the RTS Threshold value.
•Beacon Interval (Default: 100). The Beacon Interval specifies the interval time (between 20ms and 1000ms) for each beacon transmission.
•DTIM (Default: 1). The DTIM (Delivery Traffic Indication Message) specifies the data beacon rate between 1 and 255.
•Preamble Type (Default: Auto). A long transmit preamble may provide a more reliable connection or a slightly longer range. A short transmit preamble gives better performance. Auto will automatically handle both long and short preambles.
•SuperG Mode. If enabled, the Wireless Router will enable data compression, packet bursting and large frame support. This feature is available only for SuperG compatible wireless devices.
–If you Enable 108Mbps Features, the throughput of the 802.11g connection will be doubled (typically 54 Mbps) to 108 Mbps and the wireless gateway will be SuperG enabled. SuperG can be used only on Channel 6.
