Teredo Adapter Not Available

Hello circa815,

Thank you for posting on the Xbox forums. We understand that you cannot connect to Xbox party chat due to your Teredo adapter not being installed. Do you see an error message in the network settings of the Xbox Console Companion
App such as, "Teredo is unable to qualify?" There are some situations in which you would need to turn Teredo tunneling on in your router
settings. This can be done by consulting the router or gateway's manual or by contacting your internet service provider. There are some routers or gateways that do not support IPv6 which may also affect the Teredo function. Be sure to let us know the results!

Hi MORIFUY,

Probably Teredo Adapter is disabled, pelase run this command to see if it is disabled.

netsh interface Teredo show state

To re-enable the 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

Note 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.

Best Regards,

Angel.

Uninstall and reinstall the Teredo adapter

To uninstall the Teredo adapter:

1. Right-click the Start icon, and then select Command Prompt (Admin).
   
2. Run the following command from the Admin command prompt:
   netsh interface Teredo set state disable
   
3. Right-click the Start icon, and then select Device Manager.
   
4. Select View > Show Hidden Devices.
5. Select Network Adapters.
6. Identify any adapters that contain "Teredo," such as Teredo Tunneling Pseudo-Interface or
   Microsoft Teredo Tunneling Adapter. Right-click the adapter name, and then select
   Uninstall.
7. Restart your PC.

To re-enable the Teredo adapter:

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

Note 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.

Teredo is a networking protocol that’s used to establish secure communications between clients and servers, and to facilitate connectivity between devices behind routers that use network address translation
(NAT).

Failure to obtain a Teredo IP address can occur when there’s an issue with your Teredo adapter, when a device on your network is blocking the Teredo protocol. Without a Teredo IP address, you’ll be
unable to use party chat or do multiplayer gaming on Xbox Live.

Check to see if Teredo connectivity is blocked when a VPN client is connected, or while a VPN network adapter is installed

Some VPN clients will disable Teredo connectivity while the VPN client is connected, and some VPN clients that install a network adapter that will disable Teredo until the VPN adapter is removed. If you’ve
installed a VPN client and Teredo is still disabled even while the VPN client is disconnected, check to see if you have a network adapter named
TAP-Windows Adapter V9 installed:

1. Right-click the Start icon, and then select Device Manager.
   
2. Select View > Show Hidden Devices.
3. Select Network Adapters.
4. Identify any adapters that have a name like TAP-Windows Adapter V9. Right-click the adapter name, and then select
   Uninstall.
   Note While uninstalling the VPN network adapter should unblock Teredo connectivity, this will also likely cause issues with the VPN client software. If you still require VPN functionality along with Teredo support, refer to the support documentation
   for the VPN client.
