I am running a 4400 controller and cant remember how to read the access point power levels.   I know the range is 1 to 8 but what represents full power.  Is it 1 or 8.

Thanks

      Tx Power Level 2 .......................... 17 dBm
      Tx Power Level 3 .......................... 14 dBm
      Tx Power Level 4 .......................... 11 dBm

There is a lttle catch you need to know on the A side ... Depending on the channel you select the TX power is different ..Here you can read more about this ...

Example --

If you use channel 36 your max TX power is 11 dBm which is power 1 on the controller.

If you use channel 149 your max TX power is 17 dBm which is power 1 on the controller

I hope this helps...
