Wireless-G Broadband Router with SpeedBooster

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 (CTS)
frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default value
of

2347

.
