IPV6 is the latest version of IP (Internet Protocol), which identifies devices on the Internet so that they can be discovered. Every device on the Internet is identified by its IP address to communicate with other devices, and IPV6 helps with this.
IPV6 is an enhanced version of IPV4 because it supports 128-bit addressing, whereas IPV4 only supports a 32-bit addressing scheme. Although your Windows 10 computer is capable of handling the connectivity features, sometimes you may run into some problems. In this latest episode of our troubleshooting series, we solve the IPV6 “No Network Access” problem.
Some Windows 10 users complain about problems connecting to the Internet on their computer. According to them, the Internet connection is not working on their system and they notice the error “IPv6 connection: no access to network” in the network properties. If you encounter the same problem on your computer, follow the solutions suggested in this article and the problem will be solved in no time. However, you should try these workarounds first to test simpler solutions to this problem.
What causes the lack of Internet access via IPv6
When a device connects to the Internet, it receives one or more addresses on the network. Often a device receives both an IPv4 and an IPv6 address. IPv6 is a new networking standard designed to provide more connectivity to devices than the older, widely used IPv4 protocol.
When properly configured, most devices work well when establishing a network connection using at least one of these two protocols. But sometimes a device will connect and get an IPv4 address rather than an IPv6 address.
For example, when viewing the network connection details in Windows, your device might show an IPv4 network connection, but next to the IPv6 connection it says “No Internet access”. There are several reasons why this error occurs. In most cases, a precise troubleshooting step will identify the cause and solve the problem.
Resolve the problem of not accessing the Internet via IPv6
Run the Internet connection troubleshooter
Run the built-in Windows Internet Connection Troubleshooter. Windows includes several diagnostic tools designed to quickly diagnose and automatically resolve various computer problems. A troubleshooter cannot solve all problems, but it is a good place to start if you are having problems with your computer, operating system, or peripherals.
- To get started with Troubleshooter, go to Settings and enter Troubleshooting, then select Troubleshooting from the list.
- Now under “Troubleshooting” locate and select the “Internet Connections” troubleshooter. Click the “Run Troubleshooter” button and it will check for problems with your Internet connection or websites.
- Check if the Windows Troubleshooter solves the “IPv6 Connections: no Internet access” problem.
Update the network driver
The driver allows your hardware and software to communicate seamlessly. In most cases, computers cannot properly send and receive data without a driver. If the appropriate driver is not installed, the device may not work properly.
- To update your network adapter driver, you must use Device Manager. To open the Device Manager, right-click the Start button and select the Device Manager result from the context menu, or type “Device Manager” in the search box and click the Device Manager result.
- In Device Manager, you will see a list of devices connected to your computer. Find “Network Adapters,” expand it, right-click on your network device, and select “Update Drivers” from the pop-up menu.
- You will be asked if you want to automatically check for updated drivers or scan your computer for drivers.
- If you choose the first option, Windows will search your computer and the Internet for the latest drivers for your device.
- You cannot use this option without an Internet connection. If you choose the second option, you will have to search for and install drivers manually. This option requires that you first download the drivers to a computer or USB drive.
- Use another computer with a working Internet connection and download the network card drivers from the manufacturer’s official website.
- After downloading the drivers, copy them to your computer using a USB stick or other storage device and select the second option.
- Now click on “Browse…” and find the downloaded driver. Select it and click “Next”. The installation process will now begin.
- Wait until it finishes and check if the problem “IPv6 connection: no internet access” persists.
Temporarily disable your antivirus software
Your antivirus (anti-virus) software may be blocking access to the Internet and causing the “IPv6 connection: no access to the Internet” problem.
- To make sure that the installed third-party antivirus software is not causing this problem, we recommend temporarily deactivating it and see if the problem persists.
- If disabling (or removing) antivirus software helps, we recommend reinstalling it or switching to another antivirus software.
- To disable IPv6, right-click on the “Start” menu and select “Network Connections”, or go to “Settings” and click “Network and Internet”.
- In the “Network and Internet Settings” window on the left, select the type of connection (in our case “Ethernet”), and then click “Change Adapter Settings” on the right.
- Right-click on your connection and select “Properties” from the drop-down menu.
- The properties of your network connection will be displayed. In the “This connection uses the following” list, find the “Internet Protocol version 6 (TCP/IPv6)” option and uncheck it.
- Make sure that “Internet Protocol Version 4 (TCP/IPv4)” is selected (checked) and click “OK” to save your changes.
- Make sure that you can now connect to the Internet.
