Hi,
The TX power settings depends on the AP... select the AP datasheet and see the available transmit power settings..
From the GUI of the AP.. here is the steps..
AP >> Network Interface >> 802.11 G / A >> Settings >> Middle of the screen >> You have the option TRANSMITTER POWER.
or from the CLI -
power local ofdm ?
power local cck max
or
power local ofdm ?
power local ofdm max
here is the link as well..
