The default channel is 11. The 802.11b/g network is divided into 13 channels in Australia. Each channel
broadcasts on a slightly different frequency; if you are getting interference from adjacent wireless networks,
make a note of the channels that these are operating on and change your channel accordingly.
Default rate is 'Auto' and operates at the 54 Mbps data rate when possible but drops to lower rates when
necessary, dependent on signal strength and the capacity of the client stations.
Leave at default setting 'Auto' unless there is a specific requirement for multicast.
Leave as default
Enter a value between 256 (min) and 2346 (max).
A threshold, specified in bytes, that determines whether packets will be fragmented and at what size. On an
802.11 WLAN, packets that exceed the fragmentation threshold are fragmented, i.e., split into smaller units
suitable for the circuit size. Packets smaller than the specified fragmentation threshold value are not fragmented.
If you experience a high packet error rate, try to slightly increase your 'Fragmentation Threshold'. The value
should remain at its default setting of 2346 unless you are troubleshooting wireless network issues. Setting
the 'Fragmentation Threshold' too low may result in poor performance.
