How To Fix Wifi Windows 11

People are currently reading this guide.

Alright, let's dive deep into troubleshooting Wi-Fi issues on Windows 11! Frustrating, isn't it, when your internet decides to take a vacation without telling you? Don't worry, we'll get it back online.

Step 1: The Initial Checks - Let's Get the Obvious Out of the Way

Before we delve into more technical solutions, let's make sure the basics are covered. Have you tried turning it off and on again? Yes, it's a cliché, but it often works!

  • Check your Wi-Fi router and modem:

    • Power cycle: Unplug both your Wi-Fi router and your modem from the power outlet. Wait for about 30 seconds, then plug the modem back in first. Wait for it to fully power on (the lights should indicate a stable connection), and then plug the router back in. Give it a minute or two to boot up completely.
    • Visual inspection: Make sure all the cables connected to your router and modem are securely plugged in. Look for any loose connections or damaged cables.

  • Check your Windows 11 Wi-Fi:

    • Airplane mode: Ensure Airplane mode is turned off. You can usually find this in the Quick Settings panel (Windows key + A) or in the Settings app under Network & internet. The Airplane mode icon looks like a little airplane.
    • Wi-Fi is enabled: Make sure Wi-Fi is actually turned on. Again, check the Quick Settings panel or go to Settings > Network & internet > Wi-Fi and ensure the toggle is set to "On."

If a simple restart of your network devices or toggling Wi-Fi on your computer didn't do the trick, let's move on to more in-depth troubleshooting.

Step 2: Windows 11 Built-in Network Troubleshooter - Your First Software Ally

Windows 11 has a built-in network troubleshooter that can automatically diagnose and fix common network problems. Let's give it a try:

  • Accessing the troubleshooter:

    • Press the Windows key + I to open the Settings app.
    • Click on System in the left sidebar.
    • Scroll down and click on Troubleshoot.
    • Click on Other troubleshooters.
    • Find Network Adapter in the list and click the Run button next to it.

  • Following the prompts: The troubleshooter will run a series of tests and might suggest solutions. Follow any instructions it provides. It might ask you to try specific actions or even automatically fix some issues.

Step 3: Managing Your Wi-Fi Connection - Forgetting and Reconnecting

Sometimes, the saved Wi-Fi network profile can become corrupted. Forgetting the network and reconnecting can often resolve this:

  • Forgetting the network:

    • Press Windows key + I to open Settings.
    • Click on Network & internet, then select Wi-Fi.
    • Click on Manage known networks.
    • Find your Wi-Fi network name in the list and click the Forget button.

  • Reconnecting to the network:

    • Click the Wi-Fi icon in your system tray (usually in the bottom right corner of your screen).
    • Your Wi-Fi network should now appear in the list of available networks.
    • Click on your network name and then click Connect.
    • You'll be prompted to enter your Wi-Fi password. Make sure you enter it correctly.

Step 4: Updating Your Network Adapter Drivers - Keeping Things Current

Outdated or faulty network adapter drivers can cause all sorts of connectivity problems. Let's make sure you have the latest drivers installed:

  • Accessing Device Manager:

    • Right-click on the Start button (Windows logo) and select Device Manager.

  • Finding your network adapter:

    • In the Device Manager window, expand the Network adapters category.
    • Look for your wireless network adapter (it will likely have words like "Wireless," "Wi-Fi," or "802.11" in its name).

  • Updating the driver:

    • Right-click on your wireless network adapter and select Update driver.
    • You'll have two options:
      • Search automatically for updated driver software: Windows will search your computer and the internet for the latest driver. 1  
        1. answers.microsoft.com
        answers.microsoft.com
      • Browse my computer for driver software: If you've already downloaded the latest driver from the manufacturer's website, choose this option and navigate to the driver file.
    • It's generally recommended to try Search automatically first. Follow the on-screen instructions.

  • Considering manual installation: If Windows doesn't find a newer driver, or if you're still having issues, visit the website of your computer manufacturer or the manufacturer of your wireless network adapter. Look for the support or drivers section and download the latest Wi-Fi drivers for Windows 11. Then, use the "Browse my computer for driver software" option in Device Manager to install them.

Step 5: Checking Network Configuration - IP Address and DNS

Sometimes, issues with your IP address or DNS server settings can prevent you from connecting to the internet.

  • Checking your IP configuration:

    • Press Windows key + R to open the Run dialog.
    • Type cmd and press Enter to open Command Prompt.
    • In the Command Prompt window, type ipconfig /all and press Enter.
    • Look for the section related to your wireless network adapter. Note down the values for IP Address, Subnet Mask, Default Gateway, and DNS Servers.

  • Renewing your IP address:

    • In the Command Prompt window, type the following commands one by one, pressing Enter after each:
      • ipconfig /release
      • ipconfig /renew
    • This will release your current IP address and request a new one from your router.

  • Flushing the DNS cache:

    • In the same Command Prompt window, type ipconfig /flushdns and press Enter. This clears the DNS resolver cache, which can sometimes resolve issues with website access.

  • Trying different DNS servers: Sometimes, your internet service provider's DNS servers might be experiencing issues. You can try using public DNS servers like Google DNS or Cloudflare DNS:

    • Press Windows key + I to open Settings.
    • Click on Network & internet, then select Wi-Fi.
    • Click on the name of your connected Wi-Fi network.
    • Under DNS server assignment, click Edit.
    • In the "Edit DNS settings" window, select Manual from the dropdown menu.
    • Toggle on IPv4 (and IPv6 if you use it).
    • For Preferred DNS, enter 8.8.8.8 (for Google DNS) or 1.1.1.1 (for Cloudflare DNS).
    • For Alternate DNS, enter 8.8.4.4 (for Google DNS) or 1.0.0.1 (for Cloudflare DNS).
    • Click Save.

Step 6: Checking Firewall and Antivirus Software - Potential Blockers

Occasionally, your firewall or antivirus software might mistakenly block your Wi-Fi connection.

  • Temporarily disabling firewall/antivirus (use with caution!):
    • Temporarily disable your third-party firewall and antivirus software one at a time to see if that resolves the issue. Remember to re-enable them immediately after testing, as they are crucial for your computer's security.
    • If disabling one of them fixes the problem, you'll need to adjust its settings to allow your Wi-Fi connection. Consult the documentation for your specific firewall or antivirus software.
    • Windows Firewall: You can check its status by searching for "Windows Defender Firewall" in the Start menu.

Step 7: Network Reset - The Last Software Resort

If none of the above steps have worked, a network reset can sometimes resolve persistent issues by resetting all your network adapters and settings to their default configurations.

  • Performing a network reset:
    • Press Windows key + I to open Settings.
    • Click on Network & internet.
    • Scroll down and click on Advanced network settings.
    • Click on Network reset.
    • Read the warning carefully and then click the Reset now button.
    • Confirm your decision by clicking Yes.
    • Your computer will restart. After the restart, you'll need to reconnect to your Wi-Fi network and re-enter the password.

Step 8: Checking for Physical Interference - External Factors

Sometimes, the issue isn't with your computer or network hardware, but with external factors interfering with the Wi-Fi signal.

  • Obstructions: Thick walls, metal objects, and even large appliances can interfere with Wi-Fi signals. Try to minimize obstructions between your computer and your router.
  • Distance: The further you are from your router, the weaker the Wi-Fi signal will be. Try moving closer to the router to see if the connection improves.
  • Other wireless devices: Other wireless devices operating on the same frequency band (like microwaves, Bluetooth devices, and other Wi-Fi networks) can cause interference. Try turning off or moving these devices if possible.

Step 9: Considering Hardware Issues - When Software Isn't the Culprit

If you've tried all the software-based solutions and are still experiencing problems, there might be a hardware issue with your computer's Wi-Fi adapter or your router.

  • Testing on other devices: Try connecting other devices (like your smartphone or another computer) to your Wi-Fi network. If they also have trouble connecting, the issue is likely with your router or modem.
  • Checking your router's health: Look at the indicator lights on your router. Consult your router's manual to understand what the different lights mean. If certain lights are blinking abnormally or are off, it could indicate a problem with the router itself.
  • Contacting support: If you suspect a hardware issue with your computer or router, it's best to contact the manufacturer's support for further assistance or potential repairs.

Step 10: Running Network Diagnostics - Advanced Tools

Windows 11 has some more advanced network diagnostic tools that can provide more detailed information about your network connection.

  • Using Command Prompt:
    • Open Command Prompt as administrator (search for "cmd," right-click, and select "Run as administrator").
    • Try using commands like ping <website address> (e.g., ping google.com) to check if you can reach a website. High latency or packet loss indicates a connection problem.
    • Use tracert <website address> (e.g., tracert google.com) to see the path your data takes to reach a website and identify any potential bottlenecks.
    • The command netsh wlan show interfaces can provide detailed information about your wireless network adapter.
