Fix Teredo Tunneling Pseudo-Interface Error (Code-10) on your PC

Are you witnessing a yellow coloured exclamation mark in the device manager? Teredo tunneling pseudo-interface internet protocol generally faces the issue. In addition to that, another message pops up, “The device cannot start (Code 10)”. It seems that you are facing this issue and obviously there are solutions for it. 

Teredo is one of the IPv6 protocols that work over the active IPv4 tunneling mechanism. To function in a simpler way, Teredo developed a dedicated tunnel that will help you, using the IPv4, while establishing a secure internet connection. It is also a kind of technical transition that works with capable IPv6 hosts without the interference of any internet connection. 

After a detailed analysis of the issue, the experts have stated that this problem occurs when the system cannot recognize the drivers properly. That is why the update of system drivers is inevitable. Countering the statement of the experts, several users have also stated that there might be some additional solutions to resolve the issue. 

5 Quick & Effective Measures

Before going to the most effective solution list, make sure that your computer is free from any kind of Malware and other viruses. If they are present, then the process of new driver installation will not be successful. 

1. The Restoration of Teredo UI and Adapter
   

   The Device Management contains various types of application and adapter tools. In the list of network adapters present, find out the Teredo tunneling pseudo-interface. First, you have to uninstall or remove the adapter completely from your system. Then, your next task will be to update the driver software (adapter) to the latest version. 

2. Hardware Changes with CMD
   

   Before making any hardware-based changes in the Teredo tunneling pseudo-interface adapter, you have to disable the state of the adapter. In this situation, the CMD as an administrator will come in handy. Now, type “netsh” and on pressing Enter key, once again type “int teredo” and hit the spacebar. 

   After that, type “set state disabled”. This command will disable or turn off the Teredo tunneling network adapter. Just like the previous section, navigate through the Device Management window to visit the Action tab. It will show you how to scan for hardware changes. 

   Thereafter, follow all the on-screen instructions. After the successful completion of the procedure, hopefully, there will not be any yellow exclamation mark in the Device Manager. 

3. Eliminate the Exclamation Mark with Registry Editor
   

   If the above-mentioned measures fail, the Registry Editor might be able to sort the problem. In the Cortana (dedicated AI) search bar, you need to write down “regedit.exe” to open the registry editor. Find out the “HKEY_LOCAL_MACHINE” folder and open all of its sub-folders. From the System subfolder, you need to open the Current Control Set and Service folders as well. 

   Once again, from the Parameters folder, right-click on the disabled components file and set its value to 0 in the Value Data Section. After a system restart, the Teredo tunneling pseudo-interface exclamation mark issue will be resolved. 

4. Fixing the Drivers with a Third-party Application
   

   There are several third-party applications available that have the ability to fix the drivers. If you can do it, then you might not have to install the drivers once again. This procedure will only come in handy when you have already installed the latest drivers on your system. The third-party application will search the entire system for all the corrupted drivers. After that, it will repair those applications within a short span of time. 

5. The Repackaging of Data Packets
   

   When you receive the Code 10 error, as per the networking expert’s suggestions you can repackage the data packets. The process will include the IPv4, as well as the IPv6, with the help of the Teredo tunneling pseudo-interface. This is a short-term method that also helps in the synchronization of both the Internet Protocol versions. 

What about Malware Detection?

As per the expert analysis, malware has the ability to infect, as well as corrupt driver software, of your system. With the help of an anti-malware tool, search for the presence of malware in your system with the help of a full system scan. If the detection is successful, the tool itself will eliminate the malware to roll back the Teredo tunneling pseudo-interface driver to its working condition. 

The Role of NAT Firewall

The Teredo tunneling pseudo-interface helps the home and work computer systems to utilize the NAT firewall. While using the firewall, there will be no active connections in the IPv6, but a remote connection will be available with the help of a UDP (User Datagram Protocol).
