Hi John,
Changes from my earlier post (second one) were only proven to help for wifi issues.
In your case I would try disabling Idle Power Saving and Energy-Efficient Ethernet.
Hope you'll figure out working configuration, but in case, you might also want to chat with Microsoft Support. In one case they were really able to help me, unfortunately when it comes to network connectivity they may have issues with connecting remotely to your PC.
Regards,
Adam
