Why Does the Internet Stop Working After a Windows 11 Update?
If your internet connection stopped working immediately after installing a Windows 11 update, it doesn’t necessarily mean the update is faulty. During the installation process, Windows may update or replace your network driver, modify network settings, or reset certain system components. If something doesn’t work as expected, your PC may lose internet connectivity even though your router and internet service are working normally.
Some of the most common causes include:
- An incompatible or corrupted network driver was installed during the update.
- Incorrect TCP/IP or DNS settings that prevent Windows from connecting to the internet.
- A disabled or malfunctioning network adapter after the update.
- Conflicts with VPN software, antivirus, or firewall applications that block network traffic.
- A temporary bug in the latest Windows update, which Microsoft may fix in a later patch.
Before trying the more advanced solutions, it’s a good idea to start with a few basic checks. In many cases, a simple restart or reconnecting to your Wi-Fi network is enough to restore the connection.
Fix 1: Restart Your PC and Router
After installing a Windows update, temporary network glitches can sometimes prevent your PC from connecting to the internet. Restarting both your computer and your modem or Wi-Fi router refreshes the network connection and clears temporary issues that may have occurred during the update.
- Restart your Windows 11 PC.
- Turn off your modem or Wi-Fi router and unplug it from the power source.
- Wait for about 30 seconds, then plug it back in and let it reconnect to the internet.
- Once the router is fully online, reconnect your PC to the network and check if the internet is working.
If the problem persists, continue with the next solution.
Fix 2: Check if the Network Adapter Is Enabled
If your internet stopped working after a Windows 11 update, the network adapter may have been disabled, or its driver may not have loaded correctly. This can prevent Windows from detecting your Wi-Fi or Ethernet connection.
Using Network Connections
- Press Windows + R, type ncpa.cpl, and press Enter.
- Check whether your Wi-Fi or Ethernet adapter is listed.
- If the adapter appears grayed out, right-click it and select Enable.
- Wait a few seconds, then reconnect to your network.
Using Device Manager
If the adapter isn’t listed in Network Connections or still doesn’t work:
- Right-click the Start button and select Device Manager.
- Expand Network adapters.
- Look for your Wi-Fi or Ethernet adapter.
- If you see a down-arrow on the device, right-click it and choose Enable device.
- If there’s a yellow warning icon, the driver may be corrupted or incompatible. Continue to the next fix to update or reinstall the network driver.
If the adapter is missing entirely, click Action > Scan for hardware changes in Device Manager. If it still doesn’t appear, restart your PC and continue with the next solution.
Fix 3: Update or Roll Back the Network Driver
Windows updates sometimes install a newer network driver automatically. While this usually improves compatibility, it can occasionally cause your Wi-Fi or Ethernet adapter to stop working correctly. Updating, rolling back, or reinstalling the driver often resolves the issue.
Option 1: Update the Network Driver
- Right-click the Start button and select Device Manager.
- Expand Network adapters.
- Right-click your Wi-Fi or Ethernet adapter and select Update driver.
- Choose Search automatically for drivers.
- If Windows finds a newer driver, install it and restart your PC.
If Windows reports that the best driver is already installed but the problem started after a recent update, try the next option.
Option 2: Roll Back the Driver
If Windows replaced your network driver during the update, rolling back to the previous version may restore your internet connection.
- Open Device Manager and expand Network adapters.
- Double-click your network adapter.
- Open the Driver tab.
- If the Roll Back Driver button is available, click it and follow the on-screen instructions.
- Restart your PC and check your internet connection.
Note: If the Roll Back Driver option is unavailable, Windows no longer has the previous driver stored on your PC. Continue with the next option.
Option 3: Reinstall the Network Driver
Reinstalling the driver removes corrupted driver files and allows Windows to install a fresh copy.
- In Device Manager, right-click your network adapter and select Uninstall device.
- Check Attempt to remove the driver for this device only if you’re planning to install the latest driver from your PC manufacturer.
- Click Uninstall.
- Restart your computer. Windows will automatically reinstall the network adapter in most cases.
If Windows doesn’t reinstall the driver automatically, download the latest network driver from your PC or motherboard manufacturer’s support website using another device, copy it to your computer using a USB drive, and install it manually.
If your network adapter is working correctly but you still can’t access the internet, continue with the next solution.
Fix 4: Reset the TCP/IP Stack and Flush the DNS Cache
If the network adapter is working but you still can’t access the internet, Windows may be using corrupted network settings or an outdated DNS cache. Resetting the TCP/IP stack and refreshing the DNS cache can often restore your connection without affecting your personal files.
- Right-click the Start button and select Terminal (Admin) or Windows PowerShell (Admin).
- Run the following commands one at a time, pressing Enter after each one:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
- Restart your computer.
After Windows restarts, reconnect to your Wi-Fi or Ethernet network and check whether your internet connection has been restored.
What do these commands do?
- ipconfig /flushdns clears the local DNS cache, which can resolve problems accessing websites.
- ipconfig /release disconnects your current IP address from the network.
- ipconfig /renew requests a new IP address from your router.
- netsh winsock reset repairs the Windows network socket configuration, which can become corrupted after software or driver changes.
- netsh int ip reset restores the TCP/IP settings to their default state.
These commands don’t delete your personal data or installed apps, but they may reset certain network settings, so you might need to reconnect to your Wi-Fi network afterward.
Fix 5: Reset Network Settings
If your internet connection still isn’t working after trying the previous solutions, resetting the network settings can help. This process reinstalls all network adapters and restores Windows networking components to their default configuration. It’s particularly useful if the recent Windows update changed or corrupted your network settings.
Note: A network reset removes all saved Wi-Fi networks, VPN connections, and custom network settings. Make sure you know your Wi-Fi password before continuing.
- Press Windows + I to open Settings.
- Go to Network & internet > Advanced network settings.
- Under More settings, click Network reset.
- Click the Reset now button.
- Confirm the action and restart your PC when prompted.
After your computer restarts:
- Reconnect to your Wi-Fi network.
- Enter your Wi-Fi password if required.
- Check whether your internet connection has been restored.
For many users, a network reset is enough to resolve internet problems caused by incorrect network configuration, corrupted settings, or driver changes introduced by a Windows update.
Fix 6: Run the Network & Internet Troubleshooter
Windows 11 includes a built-in Network & Internet Troubleshooter that can automatically detect and fix common network problems, such as incorrect network settings, disabled services, or adapter configuration issues. While it doesn’t solve every internet problem, it’s worth running before moving on to more advanced solutions.
- Press Windows + I to open Settings.
- Go to System > Troubleshoot > Other troubleshooters.
- Find Network and Internet and click Run.
- Follow the on-screen instructions and apply any recommended fixes.
- Restart your PC if prompted.
Once the troubleshooter finishes, reconnect to your Wi-Fi or Ethernet network and check whether the internet connection is working again.
Tip: If the troubleshooter reports that it couldn’t identify the problem or couldn’t fix it, continue with the next solution.
Fix 7: Uninstall the Recent Windows Update
If your internet connection stopped working immediately after installing a Windows 11 update and none of the previous solutions helped, the update itself may be causing the problem. Uninstalling the most recent quality update can restore your network connection until Microsoft releases a permanent fix.
Note: Only remove the update if the problem started right after installing it. If the internet issue existed before the update, skip this solution.
- Press Windows + I to open Settings.
- Go to Windows Update > Update history.
- Scroll down and click Uninstall updates.
- Select the most recently installed Windows update and click Uninstall.
- Follow the on-screen instructions and restart your computer.
After your PC restarts, reconnect to your Wi-Fi or Ethernet network and check if the internet connection has been restored.
Should You Reinstall the Update?
Yes. Once Microsoft releases a newer update that fixes the issue, install it through Settings > Windows Update. Keeping Windows up to date is important for security and stability, so uninstalling an update should only be a temporary solution.
Fix 8: Disable VPN and Third-Party Security Software
If you started experiencing internet problems immediately after a Windows 11 update, a VPN client or third-party antivirus/firewall software may be interfering with your network connection. This can happen if the update changes your network configuration or installs a newer network driver that isn’t fully compatible with the software.
Temporarily disabling these applications can help determine whether they’re preventing Windows from accessing the internet.
Disable Your VPN
If you’re using a VPN:
- Disconnect from the VPN server.
- Exit the VPN application completely.
- Check if your internet connection is working normally.
If the internet works after disconnecting the VPN, update the VPN software to the latest version or reinstall it before using it again.
Temporarily Disable Third-Party Antivirus or Firewall
If you have a third-party security suite installed (such as Norton, McAfee, Bitdefender, Avast, or similar software):
- Open the antivirus or security application.
- Temporarily disable its firewall or real-time network protection.
- Test your internet connection.
Important: Only disable your antivirus or firewall for testing purposes. Re-enable it immediately after you’ve finished troubleshooting to keep your PC protected.
If disabling the security software restores your internet connection, check for software updates or reinstall the application. If the problem continues, contact the software vendor for a version that’s compatible with your current Windows 11 update.
Fix 9: Check if the Problem Is with Your Router or Internet Service Provider
If none of the previous solutions worked, the problem may not be related to Windows at all. Before spending more time troubleshooting your PC, check whether your router or internet service provider (ISP) is causing the issue.
Test Your Internet Connection
Try these quick checks:
- Connect another device, such as a smartphone or laptop, to the same Wi-Fi network.
- If other devices also can’t access the internet, restart your modem or router.
- Check whether your ISP has reported a service outage in your area.
- If you’re using an Ethernet connection, inspect the network cable for damage or try a different LAN port on the router.
What the Results Mean
- Only your Windows 11 PC has no internet: The issue is likely related to Windows, your network adapter, or its driver. Review the previous fixes, especially the driver and network reset steps.
- All devices have no internet access: The problem is most likely with your router, modem, or internet service provider. Contact your ISP if restarting your network equipment doesn’t resolve the issue.
If you’ve confirmed that your internet service is working on other devices but your Windows 11 PC still can’t connect, the issue may require assistance from your PC manufacturer, particularly if the network adapter has developed a hardware fault.
Conclusion
If your internet stopped working after a Windows 11 update, the problem is usually related to the network driver, Windows network settings, or a temporary compatibility issue introduced during the update. In most cases, updating or rolling back the network driver, resetting the network settings, or uninstalling the recent update restores the internet connection.
