How to set up a mikrotik router to work correctly with apple tv?

Question

Mikrotik

Given:
mac mini mid 2011, os sierra
apple tv3
mikrotik hap ac lite with RouterOS 6.37 (stable)
all via wifi.
Separately, everything is fine. The Internet works on the poppy, YouTube is shown on TV, everyone is happy.
But it’s worth turning on the movie on atv through the home collection - the poppy is disconnected from the router. And so several times during the film. Where to dig?
This is what the router says in the log.

Answer 1

The problem is clearly not in the AppleTV itself, but in the router. Try a different firmware version (RC, for example, or rollback to an older one) and a bootloader.
