How to Fix Ethernet Driver Not Working Error on Windows 11: Step-by-Step Solutions

Having trouble with your Ethernet connection on Windows 11? It can be frustrating when your Ethernet driver stops working, preventing you from accessing the internet. Fortunately, there are simple steps you can take to fix this problem.

This guide will walk you through easy, detailed solutions to get your Ethernet driver back in action. Each step is explained clearly, so you don’t need to be a tech expert to follow along.

By the end, you should have a working Ethernet connection again, or at least know what to do next if the problem persists. Let’s get started.

Fixing Ethernet driver issues can often be done quickly, saving you time and avoiding unnecessary stress.

Quick Note Before You Begin

Before diving into fixes, it’s good to check a few basic things. These quick checks can sometimes solve the problem right away or help narrow down the cause:

  • Is your Ethernet cable properly plugged in? Ensure both ends are firmly connected to your PC and router or modem.
  • Try a different Ethernet cable or port: Sometimes the cable or router port may be faulty.
  • Restart your computer and networking equipment: Power off your PC, modem, and router, wait 30 seconds, then turn them back on.
  • Check if Airplane mode is off: On Windows 11, click the network icon and make sure Airplane mode is disabled.

If these quick steps don’t fix the issue, proceed with the detailed troubleshooting below.

Step 1: Check Device Manager for Driver Issues

The Ethernet driver is software that allows Windows to communicate with your network hardware. If this driver is missing or has problems, your connection won’t work. Here’s how to check:

  1. Press Windows + X and select Device Manager.
  2. In the Device Manager window, expand the Network adapters section.
  3. Look for an entry related to Ethernet (often named something like “Intel Ethernet” or “Realtek PCIe GBE Family Controller”).
  4. If you see a yellow triangle with an exclamation mark or the device is missing, it indicates a driver problem.

This step is important because it tells us whether the driver is installed and functioning properly.

Step 2: Update the Ethernet Driver Automatically

Windows can often find the correct driver update automatically. Here’s how to try it:

  1. In Device Manager, right-click on your Ethernet device under Network adapters.
  2. Select Update driver.
  3. Choose Search automatically for drivers.
  4. Wait while Windows searches online and installs any available updates.

Updating drivers is important because it can fix bugs and compatibility issues that cause your Ethernet to stop working.

Step 3: Reinstall the Ethernet Driver Manually

If updating doesn’t work, try reinstalling the driver:

  1. Open Device Manager again.
  2. Right-click your Ethernet device and select Uninstall device.
  3. Confirm any prompts to remove the driver.
  4. Restart your computer. Windows will attempt to reinstall the default driver automatically.

This process removes potentially corrupted drivers and lets Windows set up fresh ones.

Step 4: Download the Latest Driver from the Manufacturer’s Website

If Windows can’t find the right driver, you can get the newest version directly from your PC or network card manufacturer:

  1. Identify your Ethernet adapter model in Device Manager.
  2. Go to the official website of your PC or Ethernet card manufacturer (e.g., Intel, Realtek, Dell).
  3. Find the support or downloads section, then search for your specific adapter model and Windows 11 drivers.
  4. Download the latest driver and run the installer.
  5. Restart your computer after installation.

This ensures you have the most compatible and up-to-date driver, which is crucial for stable network performance.

Step 5: Run Network Troubleshooter

Windows 11 includes a built-in troubleshooter that can detect and fix common network problems:

  1. Open Settings by pressing Windows + I.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Network Adapter and click Run.
  4. Follow the on-screen instructions to complete the troubleshooting process.

The troubleshooter can automatically fix configuration errors or reset network components.

Step 6: Reset Network Settings

If all else fails, resetting your network settings will clear any misconfigurations:

  1. Open Settings (Windows + I).
  2. Navigate to Network & internet > Advanced network settings.
  3. Click Network reset at the bottom.
  4. Click Reset now and confirm.
  5. Your PC will restart and network settings will return to default.

This step can resolve deep network problems but means you will lose saved Wi-Fi passwords and VPN settings, so be prepared to set those up again.

Alternative Method: Use Command Prompt for Network Fixes

If you prefer using commands, you can try these in an elevated Command Prompt window to reset network components:

  1. Type cmd in the Start menu, right-click Command Prompt, and select Run as administrator.
  2. Enter these commands one by one, pressing Enter after each:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

These commands reset network sockets, IP settings, and DNS cache, which can fix many connectivity issues.
