Hi Helloweenman,
Good day! This is Jhakesong an Independent Advisor and I will be happy to assist you with this.
I am sorry to hear about the inconvenience. Do you have a third party antivirus installed? This can cause the behavior as some antivirus software has network monitor capability.
To troubleshoot the issue, let's try to reinstall the ethernet driver.
Here's how:
- Press Windows key + X
- Open Device Manager
- Expand Network Adapters
- Look for your ethernet adapter driver, right click and uninstall
- Restart your computer, to allow windows to reinstall the driver.
It could also be caused by any startup programs installed on your computer. If after uninstalling the network driver the issue still persists, I suggest running your computer in clean boot. Here's how:

Let me know how it goes. Have a great day!
