Their bug? Is it their bug that drops the TX power 10dB when you upgrade from ROS 4.11 to ROS 5.0rc2?
Yes, that is EXACTLY what I am saying!
ADD: That was a bit short. I suspect the reason there is a difference is: They forgot to correct for Ubiquiti's "10db offset" bug. So for that you will put the blame directly on MikroTik?
If you want to use a specific company's product, know how to use it. Ubiquiti is known for that offset. I have a SR2 here. Can't even get one now, can you? And this is not the first router product that I have compensated for the now infamous Ubiquiti "10db offset".
