Not auto-negotiating to !GB stepping down to 100Mbps

[jcar]

attached  is my configuration -  

Today, all of a sudden, my ethernet is no longer auto-negotiating to 1GB.  Best I can do on either port is 100/100.  Is this indicating a failed adapter or is it something else?

Hello jcar,

Thank you for posting in Intel Ethernet Communities. 

Please provide the following information that would help in checking your request.

1.) Is this a newly configured system? When was the issue first encountered? 

2.) Is there any software or hardware changes prior to the issue? 

3.) Based on the SSU logs, there are two Ethernet controllers on the system. Can you confirm if both controllers are embedded on the system or 1 of the controller is installed on a PCIe slot?

Intel(R) Ethernet Connection (2) I219-V

Intel(R) I211 Gigabit Network Connection

4.) Is there a different system that you can test to further isolate the issue?

5.) Can you double check the established connection speed in the settings of your system: Network and Internet Settings; View your Network Properties and scroll down to Link speed (Receive/Transmit).

6.) We'd like to set your expectation that we may have a limited support on this query as you are using an Original Equipment Manufacturer(OEM) system. For OEM on-board Ethernet controller, it would be best if you can also get in touch with Asrock for further support since they have customized drivers and software to enable or alter features on your system. They are in best position where you can seek assistance so you don’t lose features or customizations of the Ethernet controller.

Awaiting to hear from you.

Should there be no response, we will follow up after 3 business days.
