I see. As I see in the picture of first message, it is NWA1123-AC HD

I would like to ask additional question. When I select channels between 149-161 with 80mhz, I see TxPower as 24dBm, but when lower the channel witdth to 40mhz, the txpower is increased to 25dBm. Why there is 1dBm reduction? 80 mhz will cover 149 to 161 and doesn't interfere, I guess? Also in the original question I see…

As an update, I replaced my 802.3af PoE injector with 802.3at compatible one 3 days ago. Thanks for the comments.

I think the maximum output power setting on Nebula indicates TX power not EIRP value, because I set it to 10dBm and after some time I see the transmit power was set to 10 dBm. So adding antenna gain and array gain to that will exceeds 10dBm which shows that setting is for TX power not for EIRP

I see, so you mean higher channels might have better coverage due to the TX power increase. I have some doubts since higher frequencies lower wall penetration capabilities but as you said it is better to measure. (Actually I was doing some measurements with some apps already but I will do it specifically every scenario…
