How to Fix ‘IPv6 No Network Access Error’ Issue – Guide

Many advances have been made since the invention of the Internet. Many more computers were connected, leading to newer protocols and technologies to improve sharing and protection on the web. Despite these advances, many PC users still struggle to connect to the Internet. It could be as simple as a wired connection or restarting the router, but in some cases it’s due to the internet protocol. In this particular case, “IPv6 connectivity: no Internet access” was a common problem for many users both on WLAN and when using a LAN cable. In that case, these users will lose all kind of Internet connection. This article will investigate the cause of this issue and provide working solutions.

IPv6 is the latest Internet protocol that is intended to replace its predecessor IPv4. The specified error can be seen in the status of your current connection. Open Run (Windows key + R) > type ncpa.cpl > OK > right click on your connection > Status. Here you will see a connection and the internet protocol you are connected to. No network access means: No DHCP server detected and no link-local address assigned. This is different from “No Internet Access”, which means a DHCP server was detected but no link-local address was assigned.

You can type ‘ipconfig /all’ at the command prompt to view your current network settings. Troubleshooting your network connection is unlikely to produce any results. All you can get is that your settings are configured correctly but the device is not responding. This error means that your PC could not meet the IPv6 Internet Protocol requirements needed for exchange and protection, so the Internet connection could not be established.

How to Fix an IPv6 no network access error

Try the following troubleshooting steps to fix an IPv6 connection issue.

  • Restart the device. When you reset a device, you also reset the device’s network connections. Many network problems that are difficult to troubleshoot can be fixed by turning a device off and then on again. During the start-up In the process, most devices automatically reconnect to previously connected wired or wireless networks.
  • Restart the router and modem. A problem with your ISP or router can result in you not being able to connect to an IPv6 address. If you have two network devices, reset the modem first, wait a minute or two, then reset the router.
  • Update the device’s operating system. See detailed instructions for how to update recent Windows, Android, iOS or macOS devices. Operating system updates often include fixes for unusual network connectivity issues.
  • Check for network device driver updates (Windows). Computer manufacturers and network device manufacturers often provide network device driver updates for equipment that works with Windows. Check the manufacturer’s support site for any available device driver updates. In some cases, it may be necessary to install more than one device driver update.
  • Update the router’s firmware. Router manufacturers tend to release periodic updates to improve device security and performance, including how devices handle IPv6 connections. The improvements often fix issues with connections between the router and your ISP, as well as connections between the router and local devices on your network. Some older routers, for example, added or improved IPv6 connection support in later firmware updates. However, some older routers lack IPv6 support entirely.
  • Run the Windows Troubleshooter (Windows 10). This app is used to fix internet connections. From the Start Menu, select Settings > Update & Security > Troubleshoot. Then select Internet Connections and then select Run the troubleshooter. Follow the onscreen instructions and allow the troubleshooter to attempt to fix the identified issues.
  • Disable and enable each of the network connections (Windows). In some cases, this can help identify a specific issue with a device or connection.
  • Reset IPv6 settings from the command prompt (Windows). See how:
  • Type cmd in the Windows system search box.
  • Right-click the command prompt desktop application that appears and choose Run as administrator.
  • Type netsh winsock reset catalog and press the Enter key.
  • Type netsh int ipv6 reset reset.log and press the Enter key.
  • Restart your system.
  • Reset network settings on iOS or Android device. This clears Wi-Fi network settings and resets cellular network settings to system defaults. For Google Pixel devices and other Android 9.0 Pie systems, go to Settings > System > Reset Options > Reset Wi-Fi, mobile & Bluetooth. This should resolve any issues resulting from manually misconfiguring an IPv6 network connection.
  • Disable any active virtual private network (VPN) connections. Many programs and VPN connections disable IPv6 connections to help secure a network connection. These programs manage and limit the exposure of a device’s network information. An active VPN connection can also automatically disable any IPv6 network connectivity. After disabling your VPN, your device should connect to the internet normally. If you find this resolves the issue, check with your VPN provider to see if they offer alternative configurations that support IPv6. Many VPN services have created methods to allow IPv6 connection while obscuring the actual IPv6 data from the device. 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.
  • Disable the firewall on Windows or macOS devices. An incorrectly configured firewall can block some or all IPv6 network connections. If IPv6 network connections work when the firewall is disabled, review the firewall settings or reset the firewall to defaults.
  • Disable the IP Helper service (Windows). This features tries to manage some aspects of IPv6 connectivity. To disable it:
  • Press Windows key+R, type services.msc in the Run box that appears and select OK.
  • This opens a list of Windows system services. Scroll through the list and find the service called IP Helper, right-click on the name of the service and choose Properties.
  • From the Startup Type drop-down list, choose Disabled and select OK.
  • Restart the system and verify that the IPv6 connection now works as expected.
  • Log in to the router as an administrator. Explore controls to ensure IPv6 connections are enabled. Change the setting to Auto Detect or Auto Setup if either option is available. If not, make sure the service is enabled. Once enabled, it may be necessary to restart the router for an IPv6 connection to be established. It may take a while for the IPv6 connection to be active and available, so wait a few more minutes after starting the router to test the connection.
  • Adjust IPv6 tunnel settings. The last step to take is to adjust how your home router and network handles IPv6 addresses. Try this by accessing the home router as administrator. Because IPv6 is designed so that each device gets a directly addressable address, the default settings for modern, up-Current routers that connect to modern, upcurrent ISPs will work fine. You can try other IPv6 settings on the router if you have problems. First, select 6to4 tunnel in router 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 on-premises devices.
  • Please contact the device manufacturer for additional support. If your IPv6 network access issues are not resolved, your last resort is to seek help from a professional.
