Hi Kornaz,
Thank you for your answer.
Actually, I had already solve the RegDB issue. I'm under OpenWRT and it is easy to rebuild the database.
So I get no error when asking for 27dBm and I think everything is correct from that side.
My problem is that, when I ask for high power (27dBm), the system acknowledge it, but when I measure the actual output power with a spectrum analyser I only see 20dBm (or even less, don't remember exactly and I don't have the spectrum analyser here any more).
This is not a HW problem because when I install the same board on a RouterOS powered mother board (RB912), I have the correct 27dBm on each channel.
That's why I was thinking about a driver issue. My idea was, that there may be something like an additional power amplifier aside AR9580 that needs to be driven by a dedicated driver.
But this is probably not the case, since you tell it's working for you. I'll have to investigate more from my side...
By the way, would you be able to check the actual output power of your device (with spectrum analyser or other device, like WifiAnalyser software on you mobile...)? Also, did you compared with other devices or with same device under RouterOS to be sure that you really have the 27dBm?
