If you think that the firmware influences the radio strength and that it's not a measurement issue: fine with me. Looks like your mind is set to this, so I won't be putting in more effort into explaining to you how things work.
Besides, what's your point complaining about it this way? Just turn back to 1.11 if you think that one's better and wait for more optimized firmware.
And just shoot me if you don't like the reply
