They often say that we don’t know what we have until it’s gone. Your missing Microsoft Teredo Tunneling adapter literally serves to prove this point. Chances are you had not given the thing much thought until it disappeared, and now that it’s gone, you have no other option but to figure out what it is and how to fix the Microsoft Teredo Tunneling adapter is missing issue.

What is the Microsoft Teredo Tunneling adapter?

In layman’s terms, it is software that enables your PC to work with both IPv4 and IPv6. Those are Internet Protocol versions that allow networking: thanks to them, every participant of the process gets a unique IP address so that it can be identified on a network. Being the latest version of the Internet Protocol, IPv6 is supposed to replace its predecessor, IPv4, which is incapable of providing enough IP addresses for the constantly growing Internet community. Today both IPv4 and IPv6 are in use, so it is essential that you be able to access any website – no matter which protocol it is running. The thing is, IPv4 and IPv6 addresses are so different that a special adapter is needed for translation purposes. This is where the Microsoft Teredo Tunneling adapter steps in. In most cases, it keeps a low profile, doing its job with no input from you. However, when it goes missing, disturbing error messages crop up.

How to resolve the Microsoft Teredo Tunneling adapter is missing problem in Windows 10?

It is pretty obvious that you need to get the Microsoft Teredo Tunneling adapter up and running again as soon as possible to be able to communicate over the net. The headache that prevents you from doing so might be caused by:

missing updates
corruption in system files
minor glitches
missing or outdated drivers

In this article, all the scenarios mentioned above are properly addressed. One of the solutions described bellow will certainly prove helpful in your case.

Make sure to start your troubleshooting with the first tip. Then keep working your way down through the fixes until you stumble across the most efficient one.

Update your OS

This is certainly the first solution to try for two reasons. First, there might be a lot of users that have recently encountered and reported the Teredo Tunneling issue, so there is probably an update designed by Microsoft to be the best means of resolving the problem. Second, your system might have missed some critical updates and might be throwing red flags to attract your attention – chances are this is how your issue with the adapter came to be. Anyway, checking for updates in Windows 10 is quite easy. This is what you should do:

Open your Start menu. Then click the gear icon to invoke Settings.
Click Update and Security to proceed.
In the right pane, locate the Check for updates button and click on it.

Your operating system will search for the updates it needs to run smoothly.

Check your system files

System file corruption is a serious problem capable of triggering multiple issues, including the Teredo Tunneling drama, on your PC. The good thing is, repairing system files is a pretty straightforward procedure since running a short command is enough to get things done:

Press the Windows logo key + X shortcut to open the Power User Menu.
Select Command Prompt (or PowerShell) with administrative privileges from the available options.
Once you are in, key the following command: sfc /scannow.
Press Enter to run the command.

Wait until the system file check is over. Finally, restart your PC and see if the Microsoft Teredo Tunneling adapter is fine now.

Install the adapter manually

If the Microsoft Teredo Tunneling adapter is still missing, installing it manually might be the best way out. Here is how you can perform the trick:

Press and hold the Windows logo key. Immediately press R. This will invoke the Run box.
Into the Run search box, type devmgmt.msc. Click Enter to proceed.
Once in Device Manager, navigate to the Action tab.
From the drop-down menu, select Add legacy hardware.
Click Next to continue.
Select the option Install the hardware that I manually select from a list (Advanced). Click Next to proceed.
Select Network adapters and click the Next button.
Navigate to the Manufacturer pane and select Microsoft.
From the Model menu, select Microsoft Teredo Tunneling Adapter.
Select Next. When the installation is complete, select Finish.
In Device Manager, open the View tab.
Select Show hidden devices.
Then double-click the Network adapter entry to open it.

Now your Microsoft Teredo Tunneling adapter should be visible. If it is not, there is no need to panic. Just move to the following fix.

Re-enable Microsoft Teredo Tunneling adapter via Command Prompt

To perform this fix, you need to open your Command Prompt:

To do this, simultaneously press the Windows logo key and R and then type ‘cmd’ (without quotes) into the Run bar.
Press Ctrl + Shift + Enter.
Click Yes when the User Account Control warning shows up.

Once the Command Prompt window is up, do the following:

Type this command: netsh interface Teredo set state disable.
Press Enter to proceed with the fix.
Once you are done, reboot your computer.
Open Command Prompt (see the instructions above).
Type ‘netsh interface Teredo set state disable’ (no quotes are needed). Hit the Enter button.
Open the Run box (Windows logo + R).
Key devmgmt.msc and press Enter.
Go to the View tab and click the option Show hidden devices.
Navigate to Network adapters and double-click it.

Check if you can see your Teredo Tunneling adapter.

No luck so far? Then keep moving down the list of our fixes.

Configure your Registry

Altered Windows Registry settings are often the culprit behind the issue you are struggling with, so it’s time for you to check if that is actually your case:

Bring up the Run box by pressing the Windows logo + R keyboard shortcut.
Type cmd and press the Ctrl + Shift + Enter combination.
When the UAC window appears, click Yes.
Key in the following command: reg query HKLSysteCurrentControlSeServiceiphlpsvTeredoCheck
Check if you see the Type EG_DWORD 0x4 line.
If yes, then your adapter is disabled. To turn it on, type netsh interface Teredo set state type=default
If you can’t see that line, input the following: reg query HKLSysteCurrentControlSeServiceTcpIpParameters
Now take a look at the DisabledComponents EGDWORD 0x…line.
If its value is not 0x0, the adapter in question is disabled.
To enable it, type reg addHKLMSstemCurrentContrlSetSericesTpip6Parameters /v DisabledComponents / REGDWORD /d 0x0 and hit Enter.
If the value is 0x0, open the Run box and input devmgmt.msc. Make sure to press Enter.
Click on View. Then select Show hidden devices.

Finally, open Network adapters. Your Teredo adapter should be here.

Fed up with your slow PC? Tired of waiting for Windows to start up? Take a look at the most common reasons behind poor performance and the best ways to deal with them here.

Somehow, thanks to the advice listed on this link: https://answers.microsoft.com/en-us/windows/forum/windows_10-networking/teredo-tunneling-adapter-is-missing/aeeae78c-13e8-4bf1-b82d-a0e492d47f50?page=2, I managed to get connected to the tunneling service without even having the adapter installed on my computer at all.

If you have the super overprotective Bit Defender service like I do, this is probably what'll punch you through:

Open the Run window and enter 'gpedit.msc'. This will open the Local Group Policy Editor. From here, go through Computer Configuration < Administrative Templates (open the drop-down menu) and select All Settings. From here, navigate down to the Set Teredo section.

Double click Set Teredo Client Port and select Enabled, then set the port to 3544. Click apply. This is a port forwarding method that directly connects you to the Teredo client. If you know how to set up port forwarding in your router settings, I recommend doing it there as well. (UDP 3544 - 3544. While you're at it, I recommend making sure UPnP is enabled.)

Double click Set Teredo Default Qualified and select Enabled, then select Enabled State. Click apply. This should force the Teredo state to remain qualified.

Double click Set Teredo Refresh Rate and select Enabled, then set the refresh rate to 2 seconds. Click apply. This may seem like overkill, but considering how shitty the Teredo service is in the first place, it's necessary.

Double click Set Teredo State and select Enabled, then select Enterprise Client. Click apply. What this will essentially do is force the Teredo interface to always be present, even if you don't have the adapter installed in the device manager (thank christ for this settings existence).

For now, minimize the Policy Editor window.

At this point, run the command prompt as an Admin and run 'netsh interface Teredo set state servername=default' and then 'netsh interface teredo show state'. You should hopefully have results that look like this:

(It should also display Local Mapping and External NAT Mapping IPs. You will most likely have your own local Microsoft Server Name be displayed.)

If it doesn't look the same, you have 1 more step to do. (I recommend doing this extra final step regardless)

Copy your server name (not including the '.' at the end) and go back into the Local Group Policy Editor. Double click Set Teredo Server Name and click Enabled. Paste the server name into the 'Enter a Teredo server name:' box and click apply. This should be the final nail in the coffin, locking in a connection with your local Teredo server.

Once again, enter 'netsh interface teredo show state' into the Admin Command Prompt to see if the results look correct.

From this point, open up the Windows Settings and click Gaming, then go to Xbox Networking. Let it do its scan and see if it connects. If it does, Congratulations!

Teredo will probably break again within a few days,eks dee.
