I have a RB2011 UiAS which the ethernet ports should be Gigabit. When I connect Ether10 to a NETGEAR GS752TP switch, the connection rate can only be 100Mbps when in Auto-Negotiation.
I've replaced the cable between the two units with the patch cable that is known to support Gigabit (tested using my laptop, with the same switch)
I've change to another port on the Mikrotik, still the same.
When I disable Auto-Negotiation, force the port to be 1Gbps, the link goes down.
Mikrotik Ether2 connecting to a NETGEAR M4100-26g, link rate 1Gbps
Has anyone seen this?
