I have an 1142 on a 2106 running 18.104.22.168. I have set the A radio to channel 149 and power level 1 (full). Unless I am misunderstanding the data sheets, that means the AP should be at 20 dBm for that channel and power setting. However, when I go to the command line and issue 'show ap config 802.11a <Cisco AP>' the output shows a max of 17 dBm. Is that output just a scripted output showing the power levels for the controller and not specific to my AP? Is my AP really at 20 dBm? The max power setting on the same 1142 when in autonomous mode at channel 149 was 20 dBm. How can I confirm this?
