WiFi Not Working on Windows 11: Troubleshooting Guide

Experiencing WiFi issues on Windows 11 can be frustrating. This guide provides a comprehensive approach to diagnosing and resolving common WiFi problems, getting you back online quickly.

1. Basic Troubleshooting Steps

Before diving into advanced solutions, try these fundamental steps:

  • Restart Your Computer: A simple restart can often resolve temporary glitches.

  • Restart Your Router: Power cycle your router by unplugging it, waiting 30 seconds, and plugging it back in.

  • Check Airplane Mode: Ensure Airplane Mode is disabled. You can find this setting in the Quick Settings panel (Windows key + A).

  • Run the Windows Network Troubleshooter: This built-in tool can automatically detect and fix common network problems.

    • To access it: Go to Settings > System > Troubleshoot > Other troubleshooters > Internet Connections and click Run.

2. Verify WiFi is Enabled and Connected

It might seem obvious, but double-checking these settings is crucial.

  • Check WiFi is Enabled:

    • Go to Settings > Network & internet > Wi-Fi. Make sure the Wi-Fi toggle is switched to On.

  • Connect to the Correct Network:

    • Click the Wi-Fi icon in the taskbar.
    • Select your network from the list and click Connect.
    • If prompted, enter the correct password.

  • Forget and Reconnect to the Network: Sometimes, saved network profiles can become corrupted. To resolve this:

    • Go to Settings > Network & internet > Wi-Fi > Manage known networks.
    • Select your network and click Forget.
    • Reconnect to the network as described above.

3. Update or Reinstall Network Adapter Drivers

Outdated or corrupted network adapter drivers are a frequent cause of WiFi issues. Ensure you have the latest drivers installed.

  • Update Drivers:

    • Open Device Manager (search for it in the Start menu).
    • Expand the Network adapters category.
    • Right-click on your wireless adapter (usually has “Wireless” or “Wi-Fi” in the name) and select Update driver.
    • Choose Search automatically for drivers.

  • Reinstall Drivers: If updating doesn’t work, try reinstalling the drivers.

    • In Device Manager, right-click on your wireless adapter and select Uninstall device.
    • Restart your computer. Windows will usually automatically reinstall the driver.
    • If it doesn’t, go back to Device Manager, right-click on your computer name at the top, and select Scan for hardware changes.

  • Download Drivers from Manufacturer’s Website: For the most reliable drivers, visit the website of your laptop manufacturer (e.g., Dell, HP, Lenovo) or the manufacturer of your wireless adapter (e.g., Intel, Broadcom) and download the latest drivers for your specific model. Install them manually.

4. Reset Network Settings

Resetting network settings can resolve deeper configuration issues.

  • Network Reset: This will remove all saved Wi-Fi networks and reset network adapters to their default settings. Be sure you have your Wi-Fi password handy.

    • Go to Settings > Network & internet > Advanced network settings > Network reset.
    • Click Reset now and confirm your choice.
    • Your computer will restart.

5. Check IP Configuration

Incorrect IP settings can prevent you from connecting to the internet.

  • Obtain IP Address Automatically (DHCP): Ensure your computer is configured to obtain an IP address automatically.

    • Open Settings > Network & internet > Wi-Fi
    • Click on the Wi-Fi network name you are connected to.
    • Next to IP assignment click Edit
    • From the dropdown, select Automatic (DHCP)
    • Click Save

  • Release and Renew IP Address: If you already have DHCP enabled, try releasing and renewing your IP address.

    • Open Command Prompt as administrator (search for it in the Start menu, right-click, and select “Run as administrator”).
    • Type ipconfig /release and press Enter.
    • Type ipconfig /renew and press Enter.
    • Close Command Prompt and check your internet connection.

6. Disable Antivirus or Firewall Temporarily

Sometimes, overly aggressive antivirus or firewall software can interfere with network connections. Temporarily disable them to see if that resolves the issue. Important: Re-enable your security software immediately after testing.

7. Check for Interference

Wireless signals can be affected by interference from other devices.

  • Move Closer to the Router: Ensure you’re within a reasonable range of the router.
  • Reduce Interference: Keep your router away from other electronic devices that might cause interference, such as microwaves or cordless phones.
  • Change WiFi Channel: Use a WiFi analyzer app (available for smartphones and computers) to identify less congested WiFi channels and configure your router to use one of those channels.

8. Troubleshoot Hardware Issues

If none of the above steps work, there might be a hardware problem.

  • Test with Another Device: Try connecting another device (e.g., smartphone, tablet) to your WiFi network to see if the problem is specific to your Windows 11 computer.
  • Contact Support: If the problem persists, contact your internet service provider or a qualified computer technician for further assistance.

By systematically working through these troubleshooting steps, you should be able to identify and resolve most WiFi problems on Windows 11.
