Hi Larry, I posted recently that I had false reported signal values from 0 to -250 dBm which are impossible for a Wi-Fi card, so I guess there must be something wrong with the qdbm -> mw and mw -> qdbm calculations somewhere, probably affecting the showed result (I guess with iwconfig ?).
So I don't think your radio is currently restricted to 10 mW but it's probably emitting with 15 mW (it's physical maximum), but it reports 10 mW. I may be wrong anyway.
