WG602v4 Manual: Advanced Wireless Settings

The default advanced wireless settings usually work well. These settings should not be changed unless you are sure it is necessary.

WMM support: WMM (Wireless Multimedia) is a subset of the 802.11e standard. WMM allows wireless traffic to have a range of priorities, depending on the kind of data. Time-dependent information, like video or audio, will have a higher priority than normal traffic. For WMM to function correctly, Wireless clients must also support WMM. The default is Disable. (Not available in Client mode.)

RTS Threshold: Request to Send Threshold. The packet size that is used to determine if it should use the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) mechanism or the CSMA/CA mechanism 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. The default is 2346.

Fragmentation Length: 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. The default is 2346.

Beacon Interval: The Beacon Interval specifies the interval time (between 20ms and 1000ms) for each beacon transmission. The default is 100.

DTIM Interval: The DTIM (Delivery Traffic Indication Message) specifies the data beacon rate between 1 and 255. The default is 1.

Preamble Type: A long transmit preamble may provide a more reliable connection or slightly longer range. A short transmit preamble gives better performance. Auto will automatically handle both long and short preamble. The default is auto.
