Wireless Settings 53 ■ DTIM Interval: A DTIM (Delivery Traffic Indication Message) is a countdown mechanism used to inform your wireless clients of the next window for listening to broadcast and multicast messages. ■ Fragmentation Threshold: this is the maximum size for directed data packets transmitted. The use of fragmentation can increase the reliability of frame transmissions. Because of sending smaller frames, collisions are much less likely to occur. ■ RTS Threshold: RTS stands for Request to Send, this parameter controls what size data packet the low level RF protocol issues to an RTS packet. ■ CTS Protection Mode: CTS stands for Clear to Send. CTS Protection Mode boosts the Router's ability to intercept 802.11b/ 802.11g transmissions. Conversely, CTS Protection Mode decreases performance. Leave this feature disabled unless you encounter severe communication difficulties between the Router and your wireless clients. ■ WMM Mode: Wireless Multimedia (WMM) mode, which supports devices that meet the 802.11E QBSS standard. Profile This feature is used to quickly set up the configuration parameters and save them into one profile for easy connection. Figure 43 Profile Screen
