This was in the early versions of Rb2011 routerboards in both rackmount (Black case) and desktop (red cased) ones.
If you used ports on the second switch chip 6 to 10 it is fine. Routerboard acknowledged this and made a change and we haven't seen it in the last year or so of stock. It was a hardware rather than firmware fix in the early rb2011s as we were instructed to return all the stock and they replaced them.

I have heard of this too, and yes it was related to Ethernet autoneg between the boxes and the fix was to put a switch in the middle. However, from what I understand it was fixed a few firmware versions ago (RouterOS fw). I won't patronise you by asking whether you have tried a firmware update... :) That said, my setup at home is RB750G to BT modem and that has always worked perfectly so there must be a limited variation or model of either Mikrotik or BT device that shows the issue.

What is the end to end latency on these lines? does it vary? Are packets actually being lost? or are they just being misordered? Dave.
