Fix IPv6 Connectivity No Internet Access on Windows 10

If you’re facing “IPv6 Connectivity: No Internet access” issue on your PC then don’t worry as today we are going to see how to fix this issue. If you will open Network and sharing center, or press Windows Key + R then type ncpa.cpl and hit Enter, then right-click on your network connection and select Status, you will see under IPv6 Connectivity that there is No Internet Access.

If under IPv6 Connectivity it says “No network access” then it means that the DHCP server was not detected and no link-local address was assigned, which is not a problem and there is nothing to worry about. But if it says “No internet access” then it means that a DHCP server was detected, but no link-local address is assigned which means there is something wrong with your IPv6 configuration. I hope now it’s clear that “No network access” and “No internet access” are two entirely different topics.

What is IPv6?

Internet Protocol Version 6 (IPv6) handles all the communications protocol, enabling data communications over a packet-switched network. IPv6 was developed by the Internet Engineering Task Force (IETF) to overcome the problems of IPv4 address exhaustion. IPv6 is the successor to Internet Protocol Version 4 (IPv4), and in future, IPv6 is intended to replace IPv4.

What is the main cause of IPv6 No Internet Access on Windows 10?

IPv6 is not capable of many devices, and fewer ISP allows it, and it is not enabled by default. But there can be other reasons such as corrupted, outdated, or incompatible network drivers, corrupted IP configuration, and Firewall might be blocking the connection, virus or malware infection etc.

So as you can see, there can be various reasons as to why you are facing the “IPv6 Connectivity: No Internet access” issue as different users have different configuration and system environment, so if something works for one user not necessarily means it will work for you and therefore, you need to try as many methods as possible.
