How to Fix Teredo Tunneling Pseudo-Interface Missing Error in Windows 11

The Teredo Tunneling Pseudo-Interface is essential for certain network services in Windows 11, especially for IPv6 connectivity over IPv4 networks. Sometimes, users notice it missing in the Device Manager, causing connectivity issues. This guide will help you fix the Teredo Tunneling Pseudo-Interface missing error step-by-step.

Whether you’re a beginner or have some technical experience, these instructions are simple and easy to follow. No need to worry about complicated jargon or confusing settings.

By the end of this article, you’ll understand why the Teredo interface is important and how to restore it properly. Let’s get started!

Follow each step carefully to avoid any further network problems.

Quick Note: Prerequisites and Checks

Before we begin troubleshooting, ensure the following:

  • You are logged in with an administrator account. Many fixes require admin privileges.
  • Your Windows 11 system is updated. Sometimes updates fix network driver issues automatically.
  • Your internet connection is stable. Some commands require internet access.
  • You have basic familiarity with Device Manager and Command Prompt.

Step 1: Check Device Manager for Hidden Devices

The Teredo Tunneling Pseudo-Interface may be hidden by default. Let’s first check for hidden devices:

  1. Press Windows + X and select Device Manager.
  2. In Device Manager, click on the menu View and select Show hidden devices.
  3. Expand the category Network adapters.
  4. Look for Teredo Tunneling Pseudo-Interface or anything similar.

Why this step matters: Sometimes Windows hides unused or disabled devices, so they don’t appear by default.

If you find the Teredo interface but it has a warning icon, try right-clicking and selecting Enable device.

Step 2: Reinstall Teredo Using Command Prompt

If the device is missing or disabled, reinstalling Teredo via command line can help.

  1. Press Windows + S, type cmd, right-click on Command Prompt, and choose Run as administrator.
  2. Type the following command and press Enter:
    netsh interface teredo set state disabled
  3. Then type:
    netsh interface teredo set state type=default
  4. Close Command Prompt and check Device Manager again for the Teredo device.

Why this helps: This disables and then resets the Teredo interface, forcing Windows to reinstall the driver.

Step 3: Use Windows Troubleshooter for Network Adapter

Windows 11 has built-in troubleshooters that can fix networking problems automatically.

  1. Click on Start and open Settings (you can press Windows + I).
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Network Adapter and click Run.
  4. Follow on-screen instructions to detect and fix issues.

This step is simple and can save you time by addressing common driver or configuration errors.

Step 4: Verify Teredo State with PowerShell

Sometimes Teredo is disabled in the registry or system settings. Let’s check its status.

  1. Press Windows + S, type PowerShell, right-click it, and select Run as administrator.
  2. Enter the command:
    Get-NetTeredoConfiguration
  3. Look for the State value in the output.

If the state is Disabled, enable it by typing:

Set-NetTeredoConfiguration -Type Default

After this, check Device Manager and your network connection again.

Step 5: Edit the Registry to Enable Teredo (Advanced)

If previous steps didn’t work, the registry might have disabled Teredo. Editing the registry requires caution.

  1. Press Windows + R, type regedit, and press Enter.
  2. Navigate to:
    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpip6Parameters
  3. Look for a DWORD value named DisabledComponents.
  4. If it exists and is not zero, right-click it and select Modify.
  5. Change its value data to 0 and click OK.
  6. Close the Registry Editor and restart your PC.

Why this matters: The DisabledComponents registry value can disable IPv6 and Teredo if set incorrectly.

Alternative Methods and Additional Tips

  • Update Network Drivers: Outdated or corrupted drivers may cause Teredo issues. Update your network adapter drivers via Device Manager or manufacturer’s website.
  • Check Group Policy Settings: On some systems, Teredo might be disabled via Group Policy. This is mostly relevant for enterprise editions of Windows.
  • Disable VPN or Firewall Temporarily: Sometimes VPNs or firewalls block Teredo. Temporarily disable them to test if Teredo reappears.

Frequently Asked Questions (FAQs)

What is the Teredo Tunneling Pseudo-Interface?

Teredo is a networking protocol that allows IPv6 connectivity over IPv4 networks by tunneling. It’s used when native IPv6 is not available.

Why does Teredo disappear from Device Manager?

It may be hidden, disabled, or removed due to Windows updates, driver issues, or configuration changes.

Can I safely delete Teredo from my system?

It’s generally not recommended because some applications and games rely on Teredo for network communication.

Do I need to enable IPv6 for Teredo to work?

Yes, Teredo depends on IPv6, so IPv6 must be enabled on your system.

What if I can’t find the Teredo device even after these steps?

It might be a deeper system issue or hardware incompatibility. Trying system restore or contacting Microsoft support may help.

When Nothing Works

If you have followed all the steps above and the Teredo Tunneling Pseudo-Interface is still missing or not working, consider these final options:

  • Run System File Checker (SFC) and DISM: These tools can repair corrupted system files.
    Open Command Prompt as administrator and run:
    sfc /scannow
    Then run:
    DISM /Online /Cleanup-Image /RestoreHealth
  • Perform a Windows Update: Check for any pending updates that might fix network issues.
  • Contact Microsoft Support: Use the official Microsoft support website for further assistance.
  • Consider System Restore: If the problem started recently, restoring Windows to an earlier point might fix the issue.

Conclusion

The Teredo Tunneling Pseudo-Interface plays an important role in network connectivity for Windows 11 users who rely on IPv6 tunneling. Its disappearance can cause frustrating connection problems, but with the right steps, it’s usually easy to fix.

Start by checking Device Manager for hidden devices, then use command-line tools to reset Teredo. Running built-in troubleshooters and verifying configurations can solve most issues. For advanced users, registry edits and driver updates provide deeper fixes.

Remember to proceed carefully, especially when modifying system settings or the registry. With patience and attention, you can restore your Teredo interface and enjoy stable network performance once again.
