Causes of IPv6 No Network Access Errors
When a device connects to the internet, it obtains one or more addresses on the network. Often, a device gets both an IPv4 address and an IPv6 address. IPv6 is a newer network standard, intended to enable a larger network of connected devices than the older, more widely-used IPv4 protocol. When properly configured, most devices work well when a network connection is made with at least one of these two protocols. But sometimes, a device connects and receives an IPv4 address and not an IPv6 address. In Windows, for example, when you look at network connection details, your device might show a connection to an IPv4 network but indicate No Internet access next to IPv6 connectivity. There are several reasons why this error occurs. Most of the time, the cause is revealed through the precise troubleshooting step that solves the problem.
How to Fix an IPv6 No Network Access Error
Try the following troubleshooting steps to fix an IPv6 connection issue. If you discover that this resolves the issue, check with your VPN provider to see if they offer alternative settings with IPv6 support. Many VPN services have devised methods to allow IPv6 connection, while also obscuring actual device IPv6 data. However, not all VPN services support IPv6 connections. See detailed instructions for managing VPN connections on Android, iOS, Windows 10, Windows 7 or 8, Windows XP, or macOS devices. Once enabled, you may need to restart the router for an IPv6 connection to be established. It may take a bit for the IPv6 connection to be active and available, so wait a few minutes longer after you start the router to test the connection. You might experiment with other IPv6 settings on the router if you experience problems. First, select 6to4 tunnel in the router’s settings to allow IPv6 and IPv4 traffic and devices to work together. Another option is to disable shared IPv6 connections. For example, some people report that disabling Share IPv6 connection on an Apple Airport router resolves IPv6 connection issues for local devices.
