IPv4 or IPv6 addresses help identify and connect other devices on the network. However, if you encounter a “No Internet Access” error when using IPv4 or IPv6, it's likely that your Internet connection is not working properly.
In this guide, Quantrimang.com will explore some troubleshooting steps to help you resolve the “IPv4/IPv6 No Internet Access” error and restore your Internet connection.
What causes the “IPv4/IPv6 No Internet Access” error?
If your PC only receives an IPv4 or IPv6 address when connecting to a network, it will display a “No Network Access” error. This can happen for a number of reasons but some common factors include problems with router configuration, faulty network drivers, incorrect DNS server addresses, and IPv6 compatibility issues.
While it can be difficult to pinpoint the exact reason, there are a few general fixes you can try to see if they solve the problem. Here are some troubleshooting methods to help you fix the “No Network Access” error on your Windows computer.
How to fix “IPv4/IPv6 No Internet Access” error on Windows

11. Next, check the option Internet Protocol Version 4 (TCP/IPv4). Do not select the IPv6 option.
12. Click OK to save changes and restart your PC.
Method 4: Configure the network adapter to automatically obtain the DNS server address
The Windows operating system allows you to set and use third-party DNS server addresses for security reasons. However, incorrect configuration of the DNS server address can cause the “No Internet Access” error.
To fix this, ensure that the network connection is set to automatically obtain IPv4/IPv6 and DNS server addresses. Here's how to do it.
1. Press Win + R to open Run.
2. Enter ncpa.cpl and click OK to open Network Connection in Control Panel.
3. Right click on your network connection and select Properties.
4. In the dialog box Propertiesselect Internet Protocol Version 4 (TCP/IP) and click the button Properties. You can also double-click IPv4 to access its properties.
5. Next, select options Obtain an IP address automatically and Obtain DNS server address automatically.
6. Next, select Validate settings upon exit and press OK to save changes.
Method 5: Reset power to router and modem
Temporary problems with your router can also cause problems with your Internet connection. To fix the problem, perform a power reset. This involves turning off the router and modem momentarily and then turning them back on.

4. Once completed, connect power, then turn on your modem and router.
5. Wait for all lights on the router to stop flashing, then check to see if the error has been resolved.
Method 6: Update network adapter driver
A damaged or outdated network adapter driver may act up, leaving you without a network connection. New drivers often come with performance improvements and bug fixes. However, a fresh installation can also help resolve issues triggered by corrupted drivers.
To update the network adapter driver:
1. Press Win + R to open Run.
2. Enter devmgmt.msc and click OK to open Device Manager.
3. Next, expand the section Network adapters.
4. Right-click the problematic network adapter (wireless or Ethernet) and select Update Driver.

6. If you don't have active Internet, click Browse my computer for drivers.
7. Next, click Let me pick from a list of available drivers on my computer.
8. Select the most recent driver update and click Next.
9. After the driver is installed, close Device Manager and restart your PC.
Some laptop manufacturers provide their own applications to manage system drivers. For example, HP, Lenovo and Asus laptops come with HP Support Assistant, Lenovo Vantage and MyASUS applications respectively. Launch the app and check if there are any new updates available for your computer.
Additionally, you can also visit your PC manufacturer's website to download the latest update for your network driver.
Method 7: Check third-party antivirus software and firewalls
Third-party antivirus software comes with a built-in firewall. Sometimes, firewalls can block legitimate connections creating problems with your network connection.
Try temporarily turning off your firewall or third-party antivirus software to see if the problem persists when the security program is turned off. Sometimes, you may need to completely uninstall a security program to disable its firewall.
