How do I enable teredo?

You say you get an ERROR because IPV6 isn’t enabled.

Exactly where is this error coming from?   What does the message say?

There’s no IPV6 address listed, so, you’re correct, it must not be enabled.  It should look like this:

Windows IP Configuration

Ethernet adapter Local Area Connection:

   Connection-specific DNS Suffix  . : my.net

   IPv4 Address. . . . . . . . . . . : 10.0.0.8

   Subnet Mask . . . . . . . . . . . : 255.255.255.0

   Default Gateway . . . . . . . . . : 10.0.0.1

Tunnel adapter isatap.tonyshome.net:

   Media State . . . . . . . . . . . : Media disconnected

   Connection-specific DNS Suffix  . : my.net

Tunnel adapter Teredo Tunneling Pseudo-Interface:

   Connection-specific DNS Suffix  . :

   IPv6 Address. . . . . . . . . . . : 2001:0:4137:9e76:3ce7:3be9:f5ff:fff7

   Link-local IPv6 Address . . . . . : fe80::3ce7:3be9:f5ff:fff7%14

   Default Gateway . . . . . . . . . : ::

Go into the DEVICE MANAGER, on the menu, select VIEW / SHOW HIDDEN DEVICES.

Under NETWORK ADAPTERS, is “Teredo Tunneling Pseudo-Adapter” listed?

Anyway, all this seems wierd.   I can’t see why Teredo would be required for the WDTV???
