This is a problem that I have had before. The ethernet connection on my desktop PC will suddenly lose internet but all other devices on the internet, wired or wireless, still connect and work just fine. The message in Windows network settings says that I can connect to other devices on my network, but it cannot reach the internet. Plugging in a Wi-Fi USB stick works just fine and it recognizes both my 5GHz and 2.4GHz networks.
Below are all of the things I have tried to fix this in the past and recently that have not worked:
When the issued first occurred, my final attempt to fix it was reformatting my whole hard drive and putting a fresh Windows on it. When I did this, the issue was still happening. What fixed it was changing out the ethernet cable. The ethernet cable I had in it previously was working while plugged into my laptop just fine and wasn't dropping connection, but did not work on my PC before and after the reformat. This time, I have two cables that are fully functional and work in every machine in my house except for my desktop. I do not want to go through the hassle of reformatting again only to find that it didn't fix the problem.

Any help or suggestions would be appreciated. Thank you.

- Using Windows CMD to reset and flush the DNS and IP addresses.
- Running Windows diagnostics.
- Running a Network Reset in Windows.
- Changing the DNS server in my ethernets IPv4 properties.
- Trying other ethernet cables.
