hear the beacons and awaken to receive the broadcast and multicast messages. The default value is 1. 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 receivmg station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clearto Send (CTS) frame to acknowledge the right to begin transmissionThe RTS Threshold value should remain at its default value of 2347.
