I am having the same issue on a 6.40.6 RB2011. Previously working Windows 10 VPN, stopped working. I have not changed ROS version, but client Windows version has probably updated.
I suspect that there's been a deprecated cipher causing a problem.
You wouldn't think so, but it does. I don't understand why, but it does.I don't think grounding has something to do with the noise levels..
To answer my own question - it's probably because the on board power supply doesn't output 12v, because they don't need it for any components. That's just conjecture, but it makes sense.I don't understand why Mikrotik designed this to use 5.5v, when 12v is much, much, much more commonly available.
That says "Yes" to me, plus the fact that you can get Canopy and Alvarion on 5.4Ghz as well seems to confirm that it's acceptable for use in the US.U-NII 2: 5.47-5.725 GHz. Both outdoor and indoor use, subject to Dynamic Frequency Selection
Diversity is not supported, and as far as I know won't be.I dont think you can use diversity in mt
