A physical issue with the top RJ45 port on a multi-port device
A mislabeled network adapter or driver error

Below is a structured troubleshooting report to help resolve the issue.

1. Check Physical Connections

Reseat the cable: Unplug the Ethernet cable from both your computer and the router/modem. You should hear a distinct "click" when plugging it back in. If it doesn't click, the plastic clip on the connector (the "top") might be broken.
Inspect the "Top" (Clip): If the small plastic clip on the head of the cable is broken off, the cable will not stay securely connected. You need to replace the cable or the connector head (requiring a crimping tool).

Method 6: Reinstall Windows

As a last resort, you may need to perform a clean installation of Windows. This will erase all data on your system drive, so ensure you back up your files first.

Go to Settings > Update & Security > Recovery.
Under "Reset this PC", click "Get started".
Choose "Remove everything" for a clean installation.
Follow the instructions to complete the process.
