How to Fix Can’t Connect to This Network Error on Windows 11

Few things are more frustrating than trying to connect to Wi-Fi on your Windows 11 PC and getting the dreaded message — “Can’t connect to this network.”

This error typically appears when Windows detects your Wi-Fi but fails to establish a proper connection. It can be caused by network driver issues, misconfigured Wi-Fi settings, outdated Windows updates, or even router-side conflicts.

Fortunately, this problem is fixable with a few straightforward troubleshooting steps. In this guide, we’ll walk you through how to fix the “Can’t Connect to This Network” error on Windows 11 — from simple checks to advanced solutions.

1. Forget and Reconnect to the Wi-Fi Network

One of the easiest and most effective fixes is to “forget” the problematic network and reconnect to it from scratch.

1. Press Windows + I to open Settings.
2. Go to Network & Internet → Wi-Fi.
3. Click Manage known networks.
4. Find your Wi-Fi name (SSID) and click Forget.
5. Now reconnect by clicking the Wi-Fi icon on the taskbar and selecting your network again.
6. Enter your Wi-Fi password and try connecting.

This clears out any stored configuration errors that might be preventing your device from connecting.

2. Restart Your PC and Router

Sometimes, the issue lies with temporary network glitches — either on your PC or router.

1. Power off your Wi-Fi router for 30 seconds.
2. Restart your Windows 11 PC.
3. Once both devices are back on, try reconnecting to the network.

This simple reset often resolves connection failures caused by cached network conflicts.

3. Run the Windows Network Troubleshooter

Windows 11 includes a built-in troubleshooter that can automatically detect and fix many common Wi-Fi and network problems.

1. Press Windows + I to open Settings.
2. Navigate to System → Troubleshoot → Other troubleshooters.
3. Find Network Adapter and click Run.
4. Follow the on-screen prompts and let Windows attempt to fix the issue.

After it completes, try reconnecting to your Wi-Fi again.

4. Update or Reinstall the Network Adapter Driver

Outdated or corrupted network drivers are a major cause of the “Can’t connect to this network” error. Updating or reinstalling them can often solve the issue.

To update your Wi-Fi driver:

1. Press Windows + X and select Device Manager.
2. Expand Network adapters.
3. Right-click your wireless adapter and select Update driver.
4. Choose Search automatically for drivers.

If no updates are found, try reinstalling the driver:

To reinstall the Wi-Fi driver:

1. Right-click your wireless adapter again and select Uninstall device.
2. Check Attempt to remove the driver for this device, then click Uninstall.
3. Restart your PC.
4. Windows will reinstall the default driver automatically.

Alternatively, visit your laptop or network card manufacturer’s website (like Intel, Realtek, or Qualcomm) to manually install the latest driver version.

5. Reset Network Settings

If your connection settings have become corrupted, a network reset will restore all network components (like Wi-Fi adapters and configurations) to their default state.

1. Press Windows + I to open Settings.
2. Go to Network & Internet → Advanced network settings.
3. Scroll down and select Network reset.
4. Click Reset now and confirm your choice.

Your PC will restart and clear all stored Wi-Fi networks. Once it boots up, reconnect to your Wi-Fi manually.

6. Check for Windows Updates

Microsoft frequently releases updates that fix network and driver compatibility issues. Keeping your Windows installation up to date can resolve this error.

1. Open Settings → Windows Update.
2. Click Check for updates.
3. Install all pending updates and restart your PC.

After updating, try connecting to your network again.

7. Change the Network Adapter Channel Width

Some routers use wider channel widths for faster connections, but not all Wi-Fi adapters support them. Adjusting this setting can resolve connection problems.

1. Press Windows + X → Device Manager.
2. Expand Network adapters and double-click your Wi-Fi adapter.
3. Go to the Advanced tab.
4. Look for an option called 802.11 Channel Width or Channel Width for 2.4GHz/5GHz.
5. Change it to 20 MHz (for 2.4GHz) or Auto (for 5GHz).
6. Click OK, then reconnect to your Wi-Fi.

This ensures your PC and router are using compatible communication settings.

8. Disable and Re-enable Your Wi-Fi Adapter

Temporarily disabling and re-enabling your adapter can refresh its network functions.

1. Press Windows + R, type ncpa.cpl, and press Enter.
2. Right-click your Wi-Fi adapter and choose Disable.
3. Wait 10 seconds, then right-click it again and choose Enable.

Now, attempt to reconnect to your Wi-Fi network.

9. Flush DNS and Reset TCP/IP Stack

Network misconfigurations or DNS cache corruption can also cause this error. Running a few commands in Command Prompt can refresh your network stack.

1. Press Windows + S, type cmd, and choose Run as administrator.
2. Run the following commands one by one, pressing Enter after each: netsh winsock reset netsh int ip reset ipconfig /release ipconfig /renew ipconfig /flushdns
3. Once done, restart your PC and reconnect to your Wi-Fi.

This method clears network cache and resets your internet protocol settings.

10. Disable IPv6 (Temporarily)

In some cases, enabling IPv6 causes compatibility issues with older routers or specific networks. Disabling it temporarily can help.

1. Press Windows + R, type ncpa.cpl, and press Enter.
2. Right-click your active Wi-Fi connection and choose Properties.
3. Uncheck Internet Protocol Version 6 (TCP/IPv6).
4. Click OK and close all windows.

Try reconnecting to the network again. If it works, you can leave IPv6 disabled — most home networks function fine with IPv4 alone.

11. Reconfigure Router Settings

If none of the above fixes work, the problem may lie with your router rather than your PC.

Try these router-side solutions:

• Reboot the router (unplug for 30 seconds, then reconnect).
• Update the router’s firmware from its admin panel.
• Change the Wi-Fi security mode (for example, switch from WPA3 to WPA2).
• Reset the router to factory defaults if necessary (check your ISP’s instructions first).

Afterward, reconnect your Windows 11 PC to the network.

12. Use Network Troubleshooting Commands

If the issue persists, you can run a quick PowerShell command that automatically diagnoses and repairs common network issues.

1. Press Windows + X and select Windows Terminal (Admin).
2. Copy and paste this command, then press Enter: msdt.exe /id NetworkDiagnosticsNetworkAdapter
3. Follow the prompts to let Windows identify and fix problems with your adapter.

This command is the same tool as the Network Troubleshooter but launched directly from PowerShell.

Wrapping Up

The “Can’t connect to this network” error in Windows 11 is usually caused by corrupted drivers, network misconfigurations, or temporary Wi-Fi conflicts.

Start with simple fixes like forgetting and reconnecting to the Wi-Fi network, restarting your PC and router, or running the Network Troubleshooter. If that doesn’t work, try resetting your network settings, updating your drivers, or adjusting your router’s configuration.

With these methods, you should be able to get your Windows 11 PC back online in no time — without the annoying connection error.
