IPv6 stands for Internet Protocol version 6. Since the invention of the Internet, there have been a lot of technical changes. The IPV6 is the latest version of Internet Protocol which is intended to supplement and eventually replace IPv4. Many businesses have already shifted to IPv6 while some are still using old IPv4.

Since the number of Internet services is increasing every day there was a risk of IPv4 getting oversubscribed? Hence IPv6 was created. Many users have encountered IPv6 Connectivity: No Internet access” error and they cannot access the Internet. If you have encountered a similar issue, there is nothing to worry about as we have shared a few solutions that could help you resolve the issue.

Solution One – Run Internet Connections Troubleshooter

Windows 10 comes with an in-built Internet connections troubleshooter. It is designed to diagnose and fix common issues related to Internet connectivity. It might not fix all problems related to Internet connections but it is a good place to start with when your Device encounters problems in Internet connections. Here are the steps to run the Internet Connections troubleshooter.

• Click Start – > Settings (gear icon)
• In the Settings window go to search functions and type troubleshoot
• Select troubleshooting from the list that populates
• In the Troubleshoot window, locate Internet Connections and click run the troubleshooter option under it.
• Windows will run Internet Connections Troubleshooter
• Wait for the tool to diagnose and fix issues.

After the troubleshooter has completed its operation, check whether you can access the Internet. If you get the IPv6 connectivity no Internet access error, move to the next solution.

Solution Two – Reset TCP/IP and Winsock

Winsock is short for Windows Socket API. It determines how windows network software should access the Internet. There is a possibility of some misconfiguration in Winsock. A Winsock reset will bring back things to normal. Here are the steps to follow.

• Click Start
• Type cmd in Cortana search and hit Enter on the keyboard
• Right-click Command prompt in the search results and click Run as administrator
• In the command prompt window, type netsh winsock reset catalog.
• Press Enter to execute the command

The above command will reset the Winsock entries to installation defaults. Now you have to reset TCP/IP.

TCP/IP is short for Transmission Control Protocol/Internet Protocol. It is a set of standard rules that allows computers to communicate on a network like the Internet. Here are the steps to reset TCP/IP.

• In the command prompt window, type netsh int ip reset, and press Enter on the keyboard.

Now check whether your computer can access the Internet. If the IPv6 connection issue persists, move to the next solution.

Solution Three – Release and Renew IP configuration settings

Every computer needs a unique IP to access the Internet. There is a possibility the IP configuration settings have become corrupt which is causing the Internet connection issues. Releasing and renewing IP configuration will set IP configuration to default and also fix minor glitches and errors.

• Open command prompt with administrative rights
• In the command prompt window, type the following commands and press Enter after each command for its execution. Wait for the first command operation to complete before typing the second command in the list.
• ipconfig /release
• ipconfig /renew
• After executing both commands, close the command prompt window.

Check whether you can access the Internet. If the issue persists, move to the next solution.

Solution Four – Disable IP helper service

Windows 10 comes with an Internet Protocol IP helper service that enables applications to retrieve network information of the local computer. It also helps modify the network configuration information. Since this service is related to Internet connections, we need to ensure the IP helper service is the cause of the problem.

Here we have discussed steps to disable the IP helper service. If the Internet connectivity comes back after disabling the IP helper service, you can conclude the IP helper service is the root cause of the “IPv6 connectivity with no network access” issue. Here are the steps to follow.

• Click Start
• Type services. msc in Cortana search and hit Enter on the keyboard
• In the Services window, locate and right-click IP helper service
• Click Properties
• In the IP helper properties window, go to the Service Status section
• Click Stop
• No go to the Startup Type section and select Disabled from the drop-down list
• Click Apply -> Ok
• Close all windows

Now check whether the Internet connectivity issue has been resolved. If you still get the IPv6 connectivity no network access error, move to the next solution

Solution Five- Temporarily disable antivirus software

According to windows experts, 3^rd party antivirus software can block Internet connectivity. To make sure the 3^rd party anti-virus is not at fault, disable the antivirus software temporarily and see if it helps. Most anti-virus software provides options like disable anti-virus protection disable anti-virus for 10 minutes, disable anti-virus till the next boot.

Check your anti-virus software documentation to know the right options. Disable the anti-virus software and check Internet connectivity. If the problem is resolved, you can uninstall the 3^rd party anti-virus software and use Windows defender instead. When you uninstall the 3^rd party anti-virus software you will get an option to turn on Windows Defender.

Use Windows Defender

Windows Defender is a part of in-built security tools in Windows 10. The anti-virus is robust and can protect your computer from various Internet threats. Here are the steps to turn on Windows Defender on your Windows 10 computer.

• Click Start – > Settings
• In the Settings window, click Update and Security
• In the Update and Security window, click windows defender in the left column
• In the right column, go to Real-time protection and turn it on
• Windows Defender will automatically prompt you to update. Do so right away as the Windows defender needs to update virus definitions to protect your computer.
• When the window with Update option populates on the screen, click Update

Solution Six – Disable IPv6

Since nothing has worked until now, you have an option of disabling IPv6 which will force the computer to use IPv4 and the Internet connectivity might get restored. Here are the steps to follow.

• Click Start -> Settings (gear icon)
• In the Settings window, click Network & Internet
• In the Network and Ethernet settings window, select the connection type. In our case, it is a wired connection hence we have chosen Ethernet in the left pane
• In the right pane, click Change adapter options
• In the Network Connections window, right-click your Internet connection and click Properties
• In the Ethernet Properties window, go to the box with a list of items and checkboxes.
• Scroll down the options to locate Internet Protocol Version 6
• Uncheck the box
• Click OK to save changes
• Close all windows and restart the computer

Check whether Internet access is available. If the issue persists, move to the next solution
