A question and a test.
If your NAS doesn't have ethtool how are you certain what speed it is connected at?
The router shows the port running at 1000Mbps.
Well, move the cable from the back of the NAS to the back of the
machine with the issue.
This way the machine gets the cable and the port which you believe to be working.
I switched the cable that came with the router for the Cat-6 I was
using when this problem arose originally, but without changing the
port.
It's now running at 1000Mbps. Clearly the (new) cable was at fault.
Thanks.
