Problem with ATV3 when using ethernet on RB962

Hi,

Found some related problems when searching google, for example this thread: http://forum.mikrotik.com/t/apple-tv-problem/74975/9

Anyway, bought an RB962 and since then i get really poor connection speed when the AppleTV 3 is hooked up via ethernet. When switching over to wifi the performance is just great.

Tried to set multicast to full on wifi since the thread above hinted about that even if not using wifi, i should be a problem resolver. But not for me! Im using capsman so i turn on multicast in the capsman settings instead of the actual wifi interface.

Can anyone help out please?
