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.
