@Facel
If you are curious about the actual negotiated configuration of your Ethernet interface, you could try this from the command line
This tells a lot about the capabilities of the interface hardware and driver. Note the Speed: and Duplex: lines. They describe my current connection.
Also, you can try
You should see all zeros on the RX errors/TX errors lines. (Don't know what your JRMC is running on but you could try the equivalent command on that host too.)
