Quick Fixes: Basic Troubleshooting Steps

  1. Restart Your Computer & Router: Simple, but often resolves temporary network blocks.
  2. Disable and Re-enable Norton: Right-click Norton icon in the system tray, choose “Disable Auto-Protect” for 15 minutes. Test your connection.
  3. Check Airplane Mode & Network Adapter: Ensure your PC is not in Airplane mode and network adapters are enabled.

If basic steps don’t fix the norton blocking internet connection fix issue, proceed to check firewall settings.

Checking Norton Firewall Settings

The Norton Smart Firewall monitors and controls internet traffic. Overly strict rules can block legitimate apps and browsers. To review and adjust settings:

  1. Open Norton and click Settings.
  2. Go to Firewall > Program Control.
  3. Scan the list for browsers, games, or apps marked as “Block” or “Custom”.
  4. Change their access to Allow.

This step often resolves the norton firewall blocking internet problem.

Adjusting Program Control & Access Rules

Occasionally, new or updated applications are blocked by default. To ensure programs have internet access:

  • On the Norton Firewall page, select Program Rules.
  • Find your application (e.g., Google Chrome, Steam, Microsoft Outlook).
  • Set their network access to Allow.
  • If the app is not listed, click Add and browse to the application’s .exe file.

Confirm and apply changes, then test your connection again.

Adding Exceptions in Norton

For persistent issues, add your app or website to Norton’s exception (exclusion) list:

  1. Open Norton > Settings > Antivirus > Scans and Risks.
  2. Scroll to Items to Exclude from Scans and Items to Exclude from Auto-Protect.
  3. Add the program folder or URL.

This prevents false positives and resolves Norton internet connection blocking for safe applications.

Update Norton & Network Drivers

Outdated Norton antivirus or network drivers can trigger connectivity problems. To update:

  • Update Norton: Open Norton, click LiveUpdate, and install all patches.
  • Update Network Drivers: Go to Device Manager > Network adapters > Right-click your adapter > Update driver.

Restart your computer after updates and check if the norton blocking internet connection fix issue is resolved.

Resetting Network Settings

If the issue remains, reset network settings in Windows:

  1. Open Settings > Network & Internet > Status.
  2. Click Network reset at the bottom.
  3. Follow prompts to restart your PC.

This clears any temporary glitches and helps restore lost connectivity.

Advanced Solutions for Persistent Issues

  • Reinstall Norton: Uninstall Norton, reboot, and reinstall the latest version from your account.

  • Contact Norton Support: If all else fails, reach out to Norton customer support for remote troubleshooting.

Prevention Tips: Avoid Future Blockages

  • Keep Norton and your operating system up-to-date.

  • Backup important settings before making major changes.
