Wreless-N ADSL2+ Gateway
reduction of the default value is recommended. In most
cases, it should remain at its default value of
23
.
RTS Threshold
Should you encounter inconsistent
data flow, only minor reduction of the default,
23
, is
recommended. If a network packet is smaller than the
preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The Gateway 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
23
.
