How to troubleshoot "No Internet Access" issue on Windows 10?

Question

I'm facing an issue on my Windows 10 PC where it shows "No Internet Access" despite being connected to the Wi-Fi network. I've tried restarting the router, disabling and re-enabling the network adapter, and running the Windows Network Troubleshooter, but none of these solutions have worked. Other devices on the same network have no connectivity issues. How can I troubleshoot and resolve this problem?

Hello,

Thank you for your question and for reaching out with your question today.

If you're experiencing a "No Internet Access" issue on your Windows 10 PC despite being connected to the Wi-Fi network, here are some additional troubleshooting steps you can try:

1. Restart your PC: Start by restarting your Windows 10 PC. Sometimes a simple reboot can resolve temporary network issues.
2. Check Wi-Fi signal strength: Ensure that your PC is within range of the Wi-Fi router and that the signal strength is strong enough for a stable connection. If possible, try moving closer to the router or connecting to a different Wi-Fi network to see if the issue persists.
3. Update network adapter driver: Visit the website of your PC's manufacturer or the network adapter manufacturer and download the latest driver for your network adapter. Install the updated driver to ensure compatibility and address any known issues.
4. Disable security software temporarily: Temporarily disable any antivirus or firewall software on your PC to check if they are causing conflicts with the network connection. If the "No Internet Access" issue is resolved after disabling the security software, consider adjusting its settings or contacting the software vendor for further assistance.
5. Reset TCP/IP stack: Open Command Prompt as an administrator and run the following commands one by one, pressing Enter after each:
   • netsh winsock reset
   • netsh int ip reset
   • Restart your PC after executing these commands and check if the issue is resolved.
6. Flush DNS cache: In Command Prompt, run the command ipconfig /flushdns to clear the DNS cache. This can help resolve any DNS-related issues that might be causing connectivity problems.
7. Reset network settings: Open Settings on your Windows 10 PC, go to "Network & Internet," and select "Status." Under the "Network reset" section, click on "Network reset" and follow the prompts to reset the network settings. Note that this will remove all network adapters and reset networking components, so ensure you have necessary network settings and credentials before proceeding.
8. Check for network adapter power-saving settings: Open Device Manager, expand the "Network adapters" category, right-click on your wireless adapter, and select "Properties." In the Power Management tab, uncheck the option to "Allow the computer to turn off this device to save power."
9. Perform a clean boot: Temporarily disable all non-essential startup programs and services to rule out any conflicts that might be causing the connectivity issue. Follow the instructions in Microsoft's documentation on how to perform a clean boot: https://support.microsoft.com/en-us/windows/how-to-perform-a-clean-boot-in-windows-d4d495d0-cb77-4ca4-b2e3-dc0be5b28088

If none of these steps resolve the "No Internet Access" issue on your Windows 10 PC, you may need to consider contacting your Internet Service Provider (ISP) or seeking further assistance from a technical professional who can diagnose and troubleshoot the problem more comprehensively.
