- Log in to your computer using the Administrator account
Once you have logged in in Safe Mode with Networking, you can go ahead and uninstall Ethernet Network Controller Drivers through the Device Manager.

- Once the adapter has been uninstalled, go to the Action Menu
- Click Scan for hardware changes
- If the device is successfully reinstalled, you will see an entry under Network Adapter
If the Driver’s re-installation fails, you will need to access another computer with a working Internet connection to download the latest Ethernet Controller Drivers. You can download Drivers by using hardware ID. Below are the steps you need to follow on your system
