Thank you for posting in our Intel ® Community.
I understand that you are facing issues with Intel® Ethernet Connection I219-V.
In this case, based on the product that you have, this onboard NIC needs to be checked by your system manufacturer for troubleshooting/issue replication or Hardware replacement.
Here I will the link for the ASRock support so you can report the problem with them directly.
I hope this helps.
