Issue: How to fix “IPv6 Connectivity: No Internet access” error
Recently I keep getting this message: IPv6 Connectivity: No Internet access and I cannot access the internet at all. I really don't understand what happened, as everything worked fine before. I tried to restart my computer multiple times, but it did not help. I am writing using my phone as I still cannot use my PC for web browsing and other online stuff. Please help!
IPv6 (Internet Protocol version 6) is a successor of IPv4, which still remains the most widely used internet protocol. Nevertheless, eventually, IPv6 will replace the older variant as the computer user count is growing steadily, and IPv4 will run out of all available IP addresses.
IPv6 Connectivity: No Internet access error is relatively common, but typically is not hard to fix. Users reported the problem after the recent Windows 10 Fall Creators update (v1709). Most likely, it is the compatibility issue between the machine and Internet Protocol Version 6 (IPv6), which does not allow the machine to establish a normal internet connection properly. Additionally, only some internet providers permit using IPv6, preventing the networking equipment from using it. Finally, the router at use might be configured to use IPv4 instead of IPv6.
The IPv6 Connectivity: No Internet access issue can occur due to different reasons, including:
- Wrong IPv6 settings
- Outdated network drivers
- Incorrect IP configuration
- IP Helper malfunction, etc.
