SolutionSteps to configure the maximum transmit power for the radios on the AP. GUI STEPS:
STEP 1: In the left window pane, Click on “Configuration” >> Devices (APs) >> Select AP and click on “Settings”.
STEP 2: Click on the “Wireless Interface” tab and select the relevant radio.
STEP 3: Change the Transmit Power High field to a particular value, as required.

STEP 1: In the controller CLI, type “configure terminal”
STEP 2: Type “interface Dot11Radio x y” where x is the AP ID and y is the radio interface number.
STEP 3: Type “localpower x” where x is the transmit power.
STEP 4: Type “exit” to go back to the global config mode.
LIMITATIONS IF ANY: The
maximum transmit power for the ‘b/g’ radio has to be an integer between
4 – 30 dBm. The maximum transmit power for the ‘a’ band is based on the
channel in use and regulatory domain the controller is set for.
To find out the maximum output power per please use the following command:
MeruController# show regulatory-domain [5GHz-channel-band or 2.4GHz-channel-band] [ap type]
AP types are:
ap150 AP150
ap180 AP180
ap200-rev1 AP200-Rev1
ap200-rev2 AP200-Rev2
