Fix Windows 11 Wired Internet Not Working After an Update

If your wired internet connection stopped working after a recent Windows 11 update, you’re not alone. Updates can sometimes cause driver conflicts or network settings to reset, leading to connectivity issues. This guide walks you through practical, step-by-step solutions to restore your wired internet connection quickly and effectively. Before starting, ensure your Ethernet cable is securely connected and your modem/router is functioning properly. Having administrative access to your PC is also necessary to perform some of the troubleshooting steps.

What You’ll Need

• Windows 11 PC with administrator rights
• Stable Ethernet cable and working modem/router
• Access to Device Manager
• Basic knowledge of network settings

Step-by-Step

1. Verify Physical Connections
   Before diving into software fixes, check that your Ethernet cable is properly plugged into your PC and router. Try disconnecting and reconnecting it. If possible, test with a different Ethernet cable or port to rule out hardware issues.
2. Restart Your Devices
   Power off your PC, modem, and router. Wait for about 30 seconds, then turn on the modem/router first, followed by your PC. This refreshes network connections and can resolve temporary glitches caused by updates.
3. Run Network Troubleshooter
   Go to Settings > System > Troubleshoot > Other troubleshooters. Click on Network Adapter and select Run the troubleshooter. Follow the on-screen instructions to identify and fix common issues automatically.
4. Update Network Drivers
   Open Device Manager (press Win + X and select it). Expand Network adapters, right-click your Ethernet device, and choose Update driver. Select Search automatically for updated driver software. If Windows finds a new driver, install it and restart your PC.
5. Reinstall Network Drivers
   If updating doesn’t work, right-click your Ethernet device in Device Manager and choose Uninstall device. Confirm and restart your PC. Windows will attempt to reinstall the driver automatically. If not, visit your PC or motherboard manufacturer’s website to download the latest driver manually.
6. Reset Network Settings
   Go to Settings > Network & Internet > Advanced network settings > Network reset. Click Reset now. This will remove all network adapters and reset network configurations to default. Your PC will restart, and you’ll need to reconnect to your network afterward.
7. Disable and Re-enable Ethernet Adapter
   In Device Manager, right-click your Ethernet adapter and select Disable device. Wait a few seconds, then right-click again and choose Enable device. This can resolve issues caused by driver conflicts after an update.
8. Check for Windows Updates
   Go to Settings > Windows Update and click Check for updates. Install any available updates, especially those related to drivers or network components, as they may fix bugs introduced by previous updates.
9. Restore System to a Previous Point
   If the issue started after a recent update, consider restoring your system to an earlier restore point. Go to Control Panel > System & Security > System > System Protection, then click System Restore and follow the prompts.

Common Mistakes

• Skipping hardware checks — Ensure the Ethernet cable and port are functioning before troubleshooting software issues.
• Ignoring driver updates — Outdated drivers can cause connectivity problems; always update or reinstall drivers after updates.
• Resetting network settings without backing up — This can remove saved Wi-Fi passwords and VPN configurations. Keep a record beforehand.
• Forgetting to restart devices — Many fixes require restarting your PC and network hardware to take effect.

Tips

• Use the Command Prompt: Run commands like ipconfig /release and ipconfig /renew to refresh IP settings.
• Disable and re-enable the Ethernet adapter regularly when troubleshooting persistent issues.
• Check your network adapter’s manufacturer website for the latest drivers specific to your hardware.
• Ensure your Windows 11 is fully updated, as patches often fix bugs affecting network connectivity.
• Consult your ISP if hardware or service issues persist beyond your PC troubleshooting.

Troubleshooting

If the above steps don’t resolve your wired internet issue, consider the following additional troubleshooting tips:

• Check for IP conflicts: Use Command Prompt to run ipconfig /all and verify your IP address is valid. If it shows an APIPA address (169.254.x.x), try renewing your IP with ipconfig /release followed by ipconfig /renew.
• Disable firewall or security software temporarily: Sometimes, security software can block network access after an update. Disable temporarily to test connectivity.
• Test on another network: Connect your PC to a different network to determine if the issue is with your PC or your network hardware.
• Check device status: In Device Manager, ensure the Ethernet device is enabled and no error icons are present.
• Perform a network reset using Command Prompt: Run netsh int ip reset and netsh winsock reset, then restart your PC.
