If a foreign channel is at least 20% better the home channel, then the system
switches to the new channel.
The
re-scan-channel
command causes the radio to perform another search.

Antenna Gain
/interface/wifi-<n>-<m>/set antenna-gain <gain>
This command lets you specify the gain of the antenna installed with your unit.
Use the
show available-config-options
command to display valid gain values (in
dBi). The displayed values vary depending on the country of operation and the
channel in use.
You must set the
<gain>
parameter to match the gain of the antenna installed
in your unit. For all countries except Korea, the default access antenna gain is
8 dBi. For Korea, the default access antenna gain is 6 dBi.

Transmit Power
Level
/interface/wifi-<n>-<m>/set tx-power <tx-power-value>
[secondary <tx-power-value>]
This command sets the transmit power for a Wi-FI radio. The range of
<tx-power-value> is limited to be valid for your country of operation, physical
channel in use, and type of antenna that is installed. Use the
show
available-config-options
command to display valid transmit power values
(in dBm). The displayed values vary depending on the country of operation and
channel in use.
The default setting is to have the radio transmit at maximum power.
The
secondary
parameter applies only to 5.8 GHz radios. It sets the transmit
power for an optional secondary channel for use with Dynamic Frequency
Selection (DFS), a regulatory requirement in some jurisdictions. The default is
to have the same transmit power level for both the primary and secondary
channel. Refer to your RF plan and site survey to determine if you need to set a
different power level for the DFS secondary channel.
