The “IPv4 No Internet Access” error typically indicates an IP address or network-related issue. Common causes include IP address conflicts or outdated network adapters. Fortunately, these issues are usually easy to resolve. In the following sections, we’ll walk you through a step-by-step guide to troubleshoot and fix the problem.
How to Fix IPv4 No Internet Access
Restart the Wi-Fi Router or Modem
The “No Internet Access” error is often linked to the Wi-Fi connection. The first step in troubleshooting is to reboot your Wi-Fi router or modem, allowing it to reassign an IP address to your device. This can renew the IPv4 address and restore your internet access.
Disable IPv6
If your IPv4 has no internet access but the IPv6 connectivity is ok, it might be due to the IP address conflict. You can try disabling IPv6 to fix the issue.
- Press Win + R to open the Run box, type Control and press Enter to open Control Panel.
- Select “Change adapter settings” from the left side.
- Right-click your network connection and select “Properties”.
- Uncheck the “Internet Protocol Version 6 (TCP/IPv6)” option.
- Click OK to save the change.
Now you can check if the IPv4 address can access the internet.
Use a VPN
If your PC shows “IPv4 no internet access”, it might be because of geo-restrictions. You can use a VPN to fix the issue.
- Choose a reliable VPN (e.g., LightningX VPN) and download it from the official site.
- Open the VPN app and sign up for an account.
- Select a server that can help you access the website.
- Click the “Connect” button. Now, the VPN is enabled, you can go to the website to see if the issue is fixed.
Tip: LightningX VPN offers both IPv4 and IPv6 addresses, preventing any IP address conflicts. It has 2,000+ servers in 50+ countries, such as Japan, Korea, Spain, the US, Russia, etc. It supports Windows/macOS/Android/iOS/tvOS/Linux/Consoles, allowing 3 simultaneous devices to connect to it. It offers a free trial for beginners to test the water.
Update the Network Drivers
Updating network drivers can fix IPv4 connectivity having no internet access. Here are the steps.
- Press Win + R, type devmgmt.msc and press Enter.
- Double-click “Network adapters” to expand.
- Right-click on your current network adapter and select “Update driver”.
- Follow the on-screen instructions to complete the update.
- Once the driver is updated, restart the PC and check if the issue is fixed.
Temporarily Disable Firewall and Third-party Antivirus Software
If you encounter the IPv4 no internet access error when browsing the web, try temporarily disabling the firewall or antivirus software.
Here’s how to turn off the firewall.
- Press Win + S, search for “Windows Security”, and open it.
- Select “Firewall & network protection” in Windows Security.
- Choose the network labeled as ‘active’.
- Toggle off “Microsoft Defender Firewall”.
To disable your third-party antivirus software, click the system tray at the bottom right, right-click on the antivirus software, and choose “Exit”, “Close”, or something like that. Then, confirm the action.
Renew the IP Address Configuration
Renewing the IP configuration can fix many problems with IPv4 address, including the internet access issue.
- Press Win + S, search for “Command Prompt”, and run it as an administrator.
- Type ipconfig /release and press Enter.
- Then, type ipconfig /renew and press Enter.
- Finally, type exit and press Enter.
Now the IP configuration should be successfully renewed. You can check if the issue is fixed.
Enable IPv4 Automatic Assignment
Enabling IPv4 automatic assignment helps prevent the use of a static IP, which can sometimes cause the “IPv4 no internet access” error.
- Press Win + S, search for “Control Panel”, and open it.
- Select “Network and Sharing Center” from the control panel.
- Click “Change adapter settings” on the left side of the page.
- Right-click on your network connection (Wi-fi) and select “Properties”.
- Double-click “Internet Protocol Version 4 (TCP/IPv4)” to open the IPv4 properties tab.
- Choose “Obtain an IP address automatically” and “Obtain DNS server address automatically” in the tab.
- Click “OK” to apply the change.
Reset the Winsock Catalog
Winsock is a set of API for Windows OS. It is used for processing internet communication, including the connection of TCP and IP. If your PC’s Winsock is corrupted, it might cause the issue with your IPv4. To fix the problem, you can reset the Winsock Catalog.
- Press Win + S, type “Command Prompt”, and run it as an administrator.
- In the window, type netsh winsock reset and press Enter.
- Type netsh int ip reset and press Enter.
- Restart your computer and see if the trouble is fixed.
Disable the Proxy
If you have a VPN on your computer, the proxy settings on your PC may remain enabled even after turning off the VPN. This active proxy can interfere with your IPv4 internet access. To resolve the issue, you can disable the proxy settings.
- Press Win + I to go to the settings.
- Select “Network & Internet”.
- Choose “Proxy” from the left menu.
- Under “Automatic proxy setup”, turn off “Automatically detect settings”.
- Under “Manual proxy setup”, toggle off “Use a proxy server”.
Contact Your ISP
An ISP is responsible for managing IP address assignments, bandwidth, and other network-related functions. If the issue persists, it could be due to problems with your ISP’s IPv4 assignment. You can contact them to seek a resolution.
To identify your ISP, simply search for “What is my ISP?” in your browser. Once you know your provider, visit their official website and look for their contact information.
Seeking Help from Microsoft Community
Microsoft community is a great resource for resolving various PC-related issues, including internet connectivity, software, and hardware problems. You can post your questions on the MS forum and check for responses that may help you find a solution.
