IPv6 No Network Access: Everything You Need to Know and How to Fix It

Whenever you have a problem with your internet connection, it is possible that the “IPv6 No Network Access” issue may cause it. The network connection can catch a lot of errors in itself, but it’s also prone to Windows system errors. In some cases, the Internet network is not to blame for the inability for Windows to get access to the Internet. Instead, the clashes within the system may cause the issue with the internet connection. The noticeable sign you can see in this problem is that the browser of the Windows PC will not be able to access a web page.

In some cases where the “IPv6 Connectivity: No Network Access” error occurs on your Windows 10 PC, some of the problems may happen as the result of this error. One of the issues which most likely happen is the “Internet Explorer cannot display the webpage” and the “No internet secured” error. In a way, the IPv6 plays an important role in rendering the network connection to be used properly on your Windows 10 PC. If there is a problem within the settings of the networking channel, then you may see the IPv6 Connectivity issue occurring on your Windows 10 PC.

Many problems in your Windows system can be easily detected if you routinely check on the system update. If you wish to look for network related problems in your Windows PC, then you can try to see the things which can indicate the problem. From “no internet secured” to “the browser cannot display the webpage” issue, the signs vary when the “IPv6 Connectivity: No Network Access” error occurs in your Windows 10 PC.

If you wish to avoid this issue, you can regularly update the Windows Update when needs to. Other than that, you can also head to the section “Network and Sharing Center” from the Windows 10 Settings. Once you get to the Settings, you can try to right-click the network connection your PC is currently connected to and choose the option “Status”. After you get there, you will see the status “No Internet Access” under the section “IPv6 Connectivity”.

In case the status under the “IPv6 Connectivity” says “No network access”, then the DHCP server is probably not detected. Aside from the server not being detected, the local link is nowhere to be found as well. Do not panic when you see this type of problem with the IPv6 Connectivity. When the IPv6 Connectivity states “No internet access”, it’s possible the DHCP server can be detected but the system cannot assign the no-link-local address. In other words, the IPv6 Connectivity may suffer a misconfiguration. If you see this error, then it means the network configuration may have to be fixed.

When it comes to network error, you may want to check the IPv4 and IPv6 connectivity first. The Internet Protocol Version 6, or commonly known as IPv6, deals with all the communications protocol in your Windows 10 PC. This, in return, can enable the data communications by using a packet of a switched network.

Things you need to know about IPv6 are that it is important for your PC network configuration. Internet Protocol Version 6 is developed by the Internet Engineering Task Force, or shortly known as IETF, to deal with the issues regarding IPv4 address exhaustion. In other words, IPv6 succeeds that of Internet Protocol Version 4 or IPv4’s service. Today, most computers have used the IPv6 configuration instead of the old IPv4 one to manage the network connectivity.

The Reasons Why “IPv6 Connectivity: No Network Access” Error Occurs on Windows 10

Due to its recent trial on new versions of Windows system, the IPv6 configuration cannot operate on many old devices. Instead of using IPv6 Connectivity, the old version of Windows system tends to use IPv4 to run the network configuration of the PC. In other words, the IPv6 is only limited to the new Windows version like Windows 10.

Other than the compatibility issue, the old version of Windows system will work as long as the ISP allows it. To make it more complicated, the ISP can only be enabled by default. As such, the compatibility issue affects other things, such as the ISP service, to react. In doing so, it creates the “IPv6 Connectivity: No Network Access” issue on your Windows PC.

While the persistent IPv6 misconfiguration may cause this issue, there are many other factors that contribute to it. Just like many issues involving Windows Modules Installer Worker and System Thread Exception Not Handled, the error will continue to exist if you do not update the drivers in your Windows system. Due to the corrupted, outdated, incompatible network drivers, and faulty IP configuration, the IPv6 misconfiguration may happen. Other than that, the Windows Firewall may also happen to block the connection because of the recent updates.

Despite the only reason being the IPv6 misconfiguration, there can be many factors which contribute to the “No Network Access” issue on your Windows 10 PC. As you may notice earlier, the compatible configuration and the system environment may help the network runs successfully. With that concept being planted in mind, you can realize that one method to fix the issue may not work for everyone. Lucky for you, there are many methods available to fix the “IPv6 Connectivity: No Network Access” error on your Windows 10 PC. Before we jump to the methods to fix this issue, you can see further explanation about the IPv6 Connectivity: No Network Access” below.

If you find this type of error, it is possible that there is an issue with your PC’s Network. Most of the “Internet Explorer cannot display the webpage” cases are caused by the issue with IPv4 and IPv6 Internet Protocol Version within the Windows system. Just like the “Internet not secured” issue, this error happens when a certain webpage you wish to open access both of IPv4 and IPv6. This will create confusion in the system which results in the Internet Explorer cannot display the webpage.

Other than the problem with IPv4 and IPv6 connectivity, “Internet Explorer cannot display the webpage” error can be caused by many things. You may also see issues involving DNS issue, Proxy issue, cache or history problems play a role in this error. Keep in mind that you always have to make sure your Internet Network is properly functional. Try to check the IPv4 or IPv6 connectivity with the other browser or the other device near you. Additionally, you can try to disable the VPNs operating in your computer. If you have considered all of these possible problems into account, you can now try to fix the “Internet Explorer cannot display the webpage” error with one of these methods below.
