experience unstable performance, please change Channel Spectrum Width to 20M.
5.7.7 Guard Interval :
Guard band between packets. For long distant connection, select Long for give better
performance.
5.7.8 Channel – Frequency
This is frequency selection you can set for device to operate on. The frequency range
available depends on the country domain you select in Country Code. For 5GHz
frequency range some have DFS characteristics earmarked by regulations. Selecting one
of these frequencies for operation may affect and delay of 2 minutes or more (possibly
up to 10 minutes in some situations) for device to attempt to establish a connection.
Auto : When checked, during startup, device automatically select the least interfering
channels
(or frequency) for the operation.
5.7.9 Data Rate
Data Rates consist of both the legacy rates and the MCS (Modulation Coding Scheme –
Only for 802.11n) rates.
6 – 54Mbps
are Legacy Rates
MCS0 to MCS7
are 802.11n rates, which uses only 1 stream.
MCS8 to MCS15
are 802.11n rates, which uses 2 streams.
Auto : The data rate selected will follow an advanced rate algorithm that takes into
condition the
amount of errors at the data rate and fine tune to the best data rate it can use.
5.7.10 Transmit Power
The maximum transmit power displayed is determined by the country code and the
maximum transmit power of the radop that is being used.
*Note on changing channels:
When the user changes the channels and if this new frequency have higher power
output permitted by regulation, the power previously selected low power level will
remains unchanged.
You need to readjust the power level to in order to take advantage higher output power
available for the channel.
Maximum : checking this box will result in maximum Tx output power overriding
regulation.
Obey Regulatory Power : checking this box will obey Tx output regulatory power by
country.
