What is the Microsoft Teredo Tunnel Adapter?
Your internet connection on any computer (Windows computer) comes with IPv4 and IPv6. These two protocols help with networking by assigning your connection an IP address. An IP address is crucial if you want to gain access to anything online. It also works as your identity. In a way, it is your internet connection’s ID.
Now, IPv4 is an older counterpart that provides the original IP Address. Meanwhile, IPv6 uses encrypted security to provide a longer IP Address. IPv4 works inside your connection and works as an actual IP Address. IPv6 operates as a camouflage for your actual IP Address but is crucial for many purposes.
Either way, both help in reinforcing the security. They also help with stabilizing the connection for you. But, the communication between the IPv4 and IPv6 depends on an adapter. That’s where Microsoft Teredo Tunneling Adapter comes into play.
Its work is to translate IP addresses between the two internet protocol versions. Hence, it is a very low-key adapter. Many people don’t know about it. But, the problem starts when it goes missing.
Imagine Microsoft Teredo Tunneling Adapter stops working. Maybe it is corrupted or undergoes an error. You will soon begin having trouble with connectivity. There will be plenty of error messages bombarding you.
That’s when the problem starts getting worse. If your Microsoft Teredo Tunnelling Adapter is Missing, don’t worry. It’s time for you to learn how to fix the issue.
How To Install Teredo Adapter On Windows 10?
You will have to download the adapter from the internet. Make sure that you have an active internet connection. Yes, there might be some errors, but it should work fine. Otherwise, visit a nearby place with a separate internet and device and download driver there.

2. Re-Enable The Teredo Adapter With Command Prompt
If you’re still having problems with the teredo adapter, there are a few more commands. Maybe the teredo adapter got disabled by some command. These can help you fix some issues and enable:
- Follow the above-given steps to run the Command prompt once again. If you don’t remember, press Windows + R and type cmd, then run as an administrator.
- You can also press CTRL + SHIFT + Enter to run as admin.
- A user account warning will show up because you are accessing it as admin. Simply click yes and move ahead.
- This is where your array of commands will begin.
- Type: ‘netsh interface teredo set state disables’ in the command prompt window.
- After doing so, reboot your computer once.
- Re-run the command prompt as admin.
- Type the following command ‘netsh interface Teredo set state type=default.’
Some people also use ‘netsh interface teredo set state disable’ after rebooting the computer. There’s no need for you to do that.
This step will re-enable the adapter. You can type devmgmt.msc and press enter. This will run the device manager for you.
In the device manager, you can go to the Network Adapter and expand it. Then check if you can find the teredo tunneling adapter there. See if this solves the problem, as well.

3. Configuring Your Registry
Windows Registry is responsible for almost everything working on your PC. Whether you have Windows 10, Windows 7, or something else, it is crucial. But sometimes, the settings change for some reason.
If you still didn’t have any luck fixing the teredo adapter problem, it’s time to take it to the next level. Here is everything you can do. Remember, this should be the last resort.
Handling a system registry requires better control and knowledge. Let’s take a look:
- Press the Windows Logo Key + R to pop up the Run window.
- Type cmd and press CTRL + Shift + Enter to launch the command prompt.
- Once again, the user account warning will pop up. Click yes and continue.
- Type the following command: ‘reg query HKL\System\CurrentControlSe\Service\iphlpsv\TeredoCheck
- Some lines will appear. See if there is a ‘Type EG+DWORD 0x4 Line.’ If it’s missing, time to type something else.
- Type: ‘reg query HKL\System\CurrentControlSe\Service\TcpIp\Parameters’
- Find ‘Disabled Components EGWORD 0x’ in the line. See if the value is 0x0 or not. If it isn’t, the adapter is disabled.
- Now you have to enable it. Type the following commands: ‘addHKLM\System\CurrentControlSet\Services\TcpIP6\Parameters\vDisabledComponents\REGDWORD/d 0x0.
- Press Enter.
- Once you reset the value, launch the device manager. Go to Network Adapter and see hidden devices. Check if you can find the teredo adapter.
Remember, these will set teredo client status and either disable or enable them. Once you get this done, restart the PC, and you should be good to go. Your driver should be enabled by now.
You can also give the registry editor a try and find disabled components there. But that could change the value of the registry, and that’s not a good idea. To avoid any further changes to your Window, we introduced these fixes.
