Your LAN or Wi-Fi/WLAN drivers might also be the problem in this case. If you have only IPv6 as the only connection, there is a chance IPv4 is disabled. If you can get an internet connection via IPv4, then you should be able the browse the web unless your drivers are faulty. Your router could even be able to assign an IPv6 address but your ISP is not able to, hence the lack of internet connection.
Your ISP or your router might therefore still be configured for IPv4, while your PC is trying to connect through IPv6 hence the conflict. Here is an approved list of ISPs that provide IPv6 internet connection. ‘IPv6 Connectivity: No Internet Access’ is normal only a very small number of ISPs allow it and those aren’t usually enabled by default. Unfortunately, there exists a huge installed base of networking equipment that is not capable of communicating via the IPv6 protocol. IPv6 is the next generation of routing and offers many improvements over IPv4, including a virtually unlimited number of addresses. Why do you get the ‘IPv6/IPv4 Connectivity: No Internet Access’ Issue? This error means that your PC was not able to successfully pass the requirements for the ipv6 internet protocol needed for exchange and protection hence it was not allowed to complete the internet connection. All you might get is that your settings are configured correctly but the device is not responding. Troubleshooting’ your network connection will likely not yield any results. You can type ‘ipconfig /all’ into the command prompt to see your current network settings. This is different from ‘ No internet access’ that means that a DHCP server was detected but, no link-local address assigned. No network access means: No DHCP server was detected, and no link-local address assigned. Here you will see a connection and the internet protocol you are connected through. Open Run (Windows key + R) > Type ncpa.cpl > OK > Right-click on your connection > Status. The stated error can be detected from the status of your current connection. IPv6 is the latest internet protocol aimed at replacing its predecessor, IPv4. This article will look into the cause of this problem and give working resolutions. When this occurs, such users lose any kind of connection to the internet. Particularly for this case, the ‘IPv6 connectivity: no internet access’ has been a common problem for several users both on Wi-Fi and when using a LAN cable. This could be simple reasons like a cable connection or restarting your router, but in some cases, it is because of the internet protocol. Despite these strides, a lot of PC users still find some difficulty connecting to the internet. A lot more computers have been interconnected, leading to newer protocols and technology to enhance exchange and protection over the web. Since the invention of the internet, a lot of advancements have been made.
