A quick search shows several people with this same problem on this device in just the past couple of weeks.

Everyone REALLY needs to send this particular problem to support@mikrotik.com so they will take it seriously! It seems to be widespread now.

Whats the auto-negotiation setting of the device on the other end of that port?
