IPv6 without access to the network or without access to the Internet: Why and what to do?

When entering the Wi-Fi or Ethernet connection status, Users can see the information that the IPv6 connection is without network access or without Internet access. If the problem is related to the Internet not working on the computer or laptop, it could be assumed that it is due to the state of the IPv6 connection, but in general this is not the case.

This tutorial details what IPv6 connection means without network access / Internet in Windows 10, 8.1 o Windows 7, if it's something you should be concerned about, if it can be fixed, and additional information that may be useful in the context of the topic we are dealing with. occupies.

Reasons why IPv6 without network or Internet access

Before we get to the reasons for the IPv6 connection status, I will point again: if you have performance problems on the internet, IPv6 is unlikely to be involved, is much more likely than individual instructions (or looking for specific errors in your browser when trying to open websites) will help you:

And now in IPv6 or IP version 6, is a new Internet protocol created due to the problem of IPv4 address shortage. Over time, IPv4 and IPv6 will be used simultaneously. But: For now, That is not the case. Most ISPs, especially when it comes to residential internet for individuals (IPv6 can be a standalone service for companies), they only provide IPv4 access.

In https://version6.ru/isp you can find a list of Internet service providers that offer IPv6 services to individuals (even though most are only found in certain regions), as well as additional configuration information and useful information related to the protocol.

Now, point by point:

1. Nowadays, the most common reason for IPv6 “does not have internet access” O “does not have access to the network” is the lack of support for the ISP protocol. And that's ok: a home internet user probably won't notice the difference.
2. The second most common reason is your Wi-Fi router's lack of IPv6 support. On some routers this support appears in the new firmware, in others (and in very common and cheap routers “old but not useless”) its appearance is not anticipated.
3. If you are sure your ISP supports IPv6 and your router supports this protocol, note that in many routers IPv6 is disabled by default and also needs specific configuration depending on the specific ISP and the type of connection. For an example of these configurations, see ASUS Wi-Fi hardware help: https://www.asus.com/ru/support/FAQ/113990

Briefly: the message that IPv6 does not have access to the network is probably normal, and if you have any problem accessing the Internet, this particular hue is not the cause of that problem.

Note: If you want IPv6 for some professional task but you only have IPv4 available, Find instructions for setting up 6in4 tunnels, it's possible.

Internet over IPv6 should work, but it says there is no network access

If you are sure your ISP supports IPv6, your router also (and is correctly configured for this protocol) Y, despite this, see in the connection status that IPv6 does not have access to the network or the Internet, You can try the following methods to fix the problem:

1. Manually configure DNS servers for IPv6 in connection properties, you can use Google IPv6 DNS servers: 2001: 4860: 4860 :: 8888 and 2001: 4860: 4860 :: 8844. To change the DNS server (you will only have to change it to IPv4, not by IPv6), Read How to change DNS server in Windows 10, 8.1 and Windows 7.
2. VPN services (I also do not exclude third-party antivirus and firewall web protection services) can block IPv6 traffic for security reasons.
3. Try to do an IPv6 reboot on the command line, running as administrator: reiniciar netsh int ipv6 and restart the computer.
4. Try to disable the service “Auxiliary IP service”. (Set the startup type to “Disabled” in services.msc and restart the computer).
5. Try updating the drivers for your network card or Wi-Fi adapter. By updating we do not mean “Update” in Device Manager or Windows Update Center 10, Instead, look for the new drivers on the hardware manufacturer's web portal and install them manually..
6. Find and re-study your ISP's required IPv6 settings carefully, Compare it to the one configured for the protocol in the connection settings or in the Wi-Fi router settings.

I hope that the material has helped to explain the situation and to find out why the connection status indicates IPv6 without access to the network.
