Maybe a regdb update to your device/CC. Can’t say about 25.12, but it works on current Snapshot here.

FWIW selecting 0,1,2,3 is still going to draw max 1mW

You can increase "cell density" parameter and leave tx power as is.

seems setting from iw is respected but from uci is rejected and it goes to max possible power

its not big issue setting that to 1 no much difference but somewhere its rejected

Create an issue then.

Sorry, that was a bit brusque.

I don’t see any change from normal expectations whether via LuCI, uci, or iw. I cannot duplicate your complaint, and that is why I suggested creating an issue.
