Teredo is tunneling ipv6 over ipv4 without my permision and I want to remove the set up.

Step 1

a. Click on Start, in the start search box type CMD,
b. In the list right click on CMD and click on Run as administrator.
c. Enter netsh environment. Type "netsh" and ENTER.
d. Again type "int teredo" and ENTER
e. Type "set state disabled" and ENTER.
f. Open Device Manager and uninstall "Teredo Tunneling Pseudo-Interface".
g. Open command prompt with administrator credentials once again.
h. Type netsh + ENTER.
i. int ipv6" + ENTER.
j. Type "set teredo client" + ENTER.

Open Device Manager and Scan for new hardware and select "Show hidden devices" from the View menu and check if you find any errors.

See this WIki, teredo tunnelling is software to encapsulate IPv6 in IPV4 packet.
As IPV6 is now available, it is no longer required.

If this message is in windows, then it is all driver problems. Try going to the intel website and looking up your motherboard, there should be several drivers in multiple categories to download, or one package, get the newest ones and install them all. Intel Driver Update Utility

Call your ISP then post back

It does not show as connected. Connect the ISP modem to main uplink port. Then connect pc to any other port. Done! Test it with network cable to pc before trying a wireless device.

Default IP is 192.168.1.1 Use web browser to access. User: Admin Password: password.




There is reset option in the back. Hold it in till it cycles. This will clear all custom settings.

1. Open command prompt with administrator credentials (Find CMD and right-click - Run as Administrator).

2. Enter netsh environment. Type "netsh" and ENTER.
3. "int teredo" and ENTER

4. "set state disabled" and ENTER.
5. Open Device Manager and uninstall "Teredo Tunneling Pseudo-Interface".

6. Open command prompt with administrator credentials once again.
7. netsh + ENTER.

8. "int ipv6" + ENTER
9. "set teredo client" + ENTER

10. Open Device Manager and Scan for new hardware.
11. Select "Show hidden devices" from the View menu. You will now see that it is present without errors with any luck.

hope this helps

RE INSTALL THE LAN DRIVERS AND DISABLE THEWINDOWS FIREWALL

Teredo is an IPv6 transition technology that provides address assignment and host-to-host automatic tunneling for unicast IPv6 traffic when IPv6/IPv4 hosts are located behind one or multiple IPv4 network address translators (NATs). To traverse IPv4 NATs, IPv6 packets are sent as IPv4-based User Datagram Protocol (UDP) messages. This article provides an overview of Teredo—including Teredo addresses and packet structures—and detailed explanations of how communication is initiated between Teredo clients, Teredo host-specific relays, and IPv6-only hosts using the IPv4 Internet, the IPv6 Internet, Teredo servers, and Teredo relays.

Teredo tunneling is a method of tunneling IPV6 traffic over an IPV4 network.99.9999999% of the networking in the world is IPv4 so why vista would want to change it is beyond me but yet another failing of Vista no wonder it's being replaced this year I just feel sorry for the mugs that have it and are still being sold it!

However back to your problem and a solution t's simple just do the following and you should be OK

To uninstall IPv6 from a computer using the command prompt
1. Open Command Prompt.

2. At the command prompt, type ipv6 uninstall, and then press ENTER.
