64CHAPTER 5: ROUTER CONFIGURATION

Fragmentation Threshold This value specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor reduction of the default value is recommended. In most cases, it should remain at its default value of 2346.

RTS Threshold Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default value of 2346.

Do not alter these parameters unless you understand the implications.

WDS WDS (Wireless Distribution System) is comprised of a bridging and/or a repeater mode. The Router supports the Wireless Distribution System (WDS) repeater mode. WDS repeating enables one or more Access Points to rebroadcast received signals to extend range and reach, though this can affect the overall throughput of data.
