I don't mean I would assume it is the Mikrotik because there is anything inherently wrong with them. I mean, I have seen reports of Ethernet issues between specific devices on certain models of Mikrotik. Without looking at this person's network, it would be tough to diagnose their issue, but I would eliminate the Tik and see if it changes (assuming all other potential grounding issues have been addressed).
You need more data from the customer Chuck. A few questions that I would have initially: Are they using shielded cable, and is it ran correctly and are the ends properly grounded? Is the rack or surge suppressor properly grounded? If they bypass the suppressor does it immediately go away? If they replace the suppressor with a new one, is it the same? Do Mikrotik ports on certain models tend to have more errors when grounding issues exist? All that I am saying is that I am certain that there are no widespread issues with powering AC devices with these suppressors. We have many UBNT AC devices that have been running without issue since 2015. We have, however had a few over the years that have taken too many near-field strikes and had a couple that will no longer negotiate at 1G. Is it possible these have taken damage, and the errors occur because they are Gigabit Ethernet devices?
