Quick Note: Prerequisites and Initial Checks

Before applying any fixes, make sure your internet connection is stable. Sometimes, a weak or disconnected network causes error 0x80072726. Try opening a website or running a speed test to confirm connectivity.

Also, restart your computer. A simple reboot can clear temporary glitches that might trigger this error.

Ensure your Windows 11 system is not blocking the connection via firewall or antivirus settings. Temporarily disabling these can help identify if they are the cause.

Having administrative access on your computer is important because some fixes require changing system settings.

Step 1: Run the Windows Network Troubleshooter

The Windows Network Troubleshooter is a built-in tool designed to automatically detect and fix common network problems.

  1. Click the Start button and select Settings (gear icon).
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Network Adapter and click Run.
  4. Follow the on-screen instructions to identify and fix issues.

This step is important because it can fix common network configuration problems without requiring advanced technical skills.

Step 2: Reset Your Network Settings

If the troubleshooter does not solve the problem, resetting your network settings can clear corrupted configurations that cause connection errors.

  1. Open Settings again.
  2. Navigate to Network & Internet.
  3. Scroll down and click Advanced network settings.
  4. Select Network reset.
  5. Click Reset now and confirm.

After resetting, your PC will restart, and your network adapters will return to default settings. You will need to reconnect to your Wi-Fi or Ethernet network afterward.

Step 3: Flush DNS and Reset TCP/IP Stack

Sometimes, DNS cache or TCP/IP stack corruption causes network errors. Flushing DNS and resetting TCP/IP can fix these issues.

To do this:

  1. Press Windows + S, type cmd, then right-click Command Prompt and select Run as administrator.
  2. In the command window, type the following commands one by one, pressing Enter after each:
ipconfig /flushdns
netsh int ip reset
netsh winsock reset

After running these commands, restart your computer. This process clears network-related caches and resets essential network components.

Step 4: Check Firewall and Antivirus Settings

Sometimes, firewall or antivirus programs block certain network connections, causing error 0x80072726.

To check:

  1. Open Windows Security by searching for it in the Start menu.
  2. Go to Firewall & network protection.
  3. Temporarily turn off the firewall for your active network (Private or Public).
  4. If you have third-party antivirus software, open it and look for firewall settings to disable temporarily.
  5. Try the network activity again to see if the error persists.

If disabling the firewall or antivirus fixes the problem, add the affected program or service to the firewall’s exception list to maintain security while allowing proper connection.

Step 5: Update Network Drivers

Outdated or corrupted network drivers can cause connection errors.

To update your drivers:

  1. Press Windows + X and select Device Manager.
  2. Expand the Network adapters section.
  3. Right-click your network device (Wi-Fi or Ethernet) and choose Update driver.
  4. Select Search automatically for drivers and follow instructions.
  5. Restart your PC after the update completes.

Keeping drivers updated ensures compatibility and smooth network operation.

Alternative Method: Use Windows Update for Driver Updates

Sometimes Windows Update provides the latest drivers:

  1. Go to Settings > Windows Update.
  2. Click Check for updates.
  3. If any network driver updates are available, install them.
