Fragment Length
This specifies the number of bytes that are transmitted before a frame is fragmented. The longer
the fragment, the more data is sent. However, where clients are working with low signal strengths
when the channel bit error rate is high, then errors are likely and this will cause re-transmits to
obtain error free packets. As shorter fragment lengths will be faster to re-transmit, then in marginal
networks it is recommended that the fragment length be relatively short to optimise throughput.
Note that setting the fragment length too short will adversely affect throughput. The available range
is 256 to 2346 bytes. The default value is
2346
.
RTS/CTS Threshold
Packets larger than the specified value are preceded by an RTS/CTS handshake. Enter a value
between 256 and 2346 to specify the value of the RTS /CTS Threshold. The default value is
2346
.
If there are a large number of clients on the access point, then the number of collisions can be
reduced by lowering the RTS/CTS threshold value. This threshold setting can be used to eliminate
the “hidden node” problem. If the RTS/CTS Threshold is too short, then throughput will be
degraded.
Hide SSID
The SSID value is broadcast by default as this simplifies installation and commissioning. However,
the SSID value can be easily received and so provides a potential security problem. For higher
security networks, it is recommended that the Hide SSID checkbox is set. The default is
Off
.
