Windows 10: Missing Teredo network adapter

I have gone through too many sources for a solution but to no avail so I am resorting to posting here to get rid of all that clutter and start over.

So as my title says, I am currently missing a Teredo Network Adapter in my Legacy hardware section under Network Adapters. I think it's the reason I am unable to play online in Forza Horizon 4. My Xbox Live Settings shows that my Server Connectivity is Blocked and my NAT type is Moderate.

Some of the solutions point to installing a Teredo Tunneling Network Adapter from Legacy Hardware but the problem is I can't find it. How do I somehow re-install this?

Missing Microsoft Teredo Tunneling Adapter from Legacy Hardware

Hello,

Please try these suggestions:

Method 1:

Step 1: Modify TCPIPv6 Parameters through Windows Registry

1. Press “Windows” + “R” keys to load the Run dialog box.Type “regedit” and press Enter.
2. Inside Windows Registry, navigate (from the left pane) and highlight this key.
3. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters
4. At the right pane, double-click to modify the DisabledComponents key.
5. Set the DisabledComponents Value data to 0 (Zero) and select OK.
6. Close Registry Editor.
7. Restart your computer.
8. Navigate to device management.
9. Check if the Teredo tunneling adapter exists and working in device manager. To do that:

• From the View menu choose Show hidden devices.
• If the device manager's screen doesn't show any errors (and is without an exclamation mark) next to MS Teredo Tunneling Adapter then your problem is solved and the Teredo tunneling should work without problems.

If you face a screen with a yellow exclamation mark next to Microsoft Teredo Tunneling adapter.

Step 2: Uninstall all Teredo Tunneling Adapters & Interfaces.

1. Right-Click and Uninstall the Teredo Tunneling Pseudo-Interface.
2. Uninstall also all Microsoft Teredo Tunneling Adapters (e.g. Microsoft Teredo Tunneling Adapter #2 or #3 or #4, etc.)
3. Re-install Microsoft Teredo Tunneling Adapter by following the steps from this tutorial: How to install Microsoft Teredo Tunneling Adapter
4. If after re-installing teredo tunneling, you still have problems then proceed to Step 3.

Step 3. Enable Teredo Client using NETSH command

1. Right click at Command Prompt and select Run as Administrator.
2. At command prompt window type the following commands in this order and press Enter after typing each one of them.

netsh

int teredo

set state disabled

int ipv6

set teredo client

3. Close command prompt.

4. Open Device manager.

5. Select View > Show Hidden Devices. The Teredo Tunneling Pseudo Interface reappears and should be working without problems now.

Method 2 (not work in Windows 10 Home):

Open Group Policy Editor by running gpedit.msc command. Under Computer Configuration in the tree view, expand Administrative Templates then click All Settings. Look for "Set Teredo State", then double-click that. You will then enable the
policy and set the state below to "Enterprise Client" from what it was before in the dropdown menu under "Select from the following states".

Hope this helps!

2. Teredo Tunneling Adapter Is Missing

 

Microsoft Teredo Tunneling Adapter not Found

Hi,

It started off from teredo unable to qualify for Xbox connection.

Then, I tried following tons of suggestions through showing hidden drivers in Device manager, changing DisabledComponents value to 0.

However, I still cannot find Microsoft Teredo Tunneling Adapter.

I tried to install it by adding legacy hardware with all ways, but there was no Microsoft Teredo Tunneling Adapter in the list of the Microsoft Network Adapter .

 

Teredo Tunneling Pseudo-Interface Adapter Missing

Hello,



Thank you for writing to Microsoft Community Forums.



I would like to know the reason you are trying to install the Teredo Tunneling Pseudo-Interface Adapter, so that we can suggest you alternatives. If you are trying to install it for Xbox app on Windows Computer then we can have the dedicated team look
into it.



However here are some steps that you can try. To enable Teredo adapter:

• Right-click the Start icon, and then select
  Command Prompt (Admin).
  
• Run the following command from the Admin command prompt:
  
  • netsh interface Teredo set state type=default
    
• 
  

**The Microsoft Teredo Tunneling Adapter will reinstall automatically. Don’t install the Teredo Tunneling Pseudo-Interface adapter manually in Device Manager, as this may cause issues with Teredo functionality**



Also check to see if Teredo is disabled in the registry by a program or by a manually configured registry value.

• Right-click the Start icon, and then select
  Command Prompt (Admin).
  
• Run the following command from the Admin command prompt:
  
  • reg query HKLM\System\CurrentControlSet\Services\iphlpsvc\Teredo
    
  • If the output includes the following line, Teredo has been disabled:
    
  • Type REG_DWORD 0x4
    
• You can re-enable Teredo by running the following command from the Admin command prompt:
  
  • netsh interface Teredo set state type=default
    

Check the TcpIp6 registry path:

• Right-click the Start icon, and then select
  Command Prompt (Admin).
  
• Run the following command from the Admin command prompt:
  
  • reg query HKLM\System\CurrentControlSet\Services\TcpIp6\Parameters
    
  • If the output includes the following line, and the value displayed is not
    0x0, Teredo may have been disabled:
    
  • DisabledComponents REG_DWORD 0x8e
    
• You can re-enable Teredo by running the following command from the Admin command prompt:
  
  • reg add HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters /v DisabledComponents /t REG_DWORD /d 0x0
    

Important: The registry is a database in Windows that contains important information about system hardware, installed programs and settings, and profiles of each of the user accounts on the computer. Windows often reads and updates the information
in the registry.

Normally, software programs make registry changes automatically. You should not make unnecessary changes to the registry. Changing registry files incorrectly can cause Windows to stop working or make Windows report the wrong information.



**Please take a backup of the registry. To take back up, follow the steps mentioned in article:

How to back up and restore the registry in Windows.




Hope it helps.
