into multiple packets . If you experience a high packet
error rate, you may slightly increase the Fragmentation
Threshold .SettingtheFragmentationThresholdtoolow
may result in poor network performance . Only minor
reductionofthedefaultvalueisrecommended .Inmost
cases,itshouldremainatitsdefaultvalueof2346 .
RTS Threshold
 Should you encounter inconsistent
dataflow,onlyminorreductionofthedefaultvalue,2347,
is recommended . If a network packet is smaller than 
the preset RTS threshold size, the RTS/CTS mechanism
will not be enabled . The Valet 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 RTSThreshold value should remain at
