Fix #3: Change the Wireless Network Adapter’s Settings.

There are instances when the Windows 10 Wifi won’t turn on issue arises because of corrupt or incorrect network settings. To fix this, some users simply changed their wireless network adapter’s settings.

Here’s how:

  1. Open the Run dialog box by pressing the Windows + R combination.
  2. Enter devmgmt.msc into the text field.
  3. Hit Enter.
  4. At this point, the Device Manager window should open. Expand the Network Adapters section.
  5. Right-click on the Wifi Network Adapter option and choose Properties.
  6. Navigate to the Advanced tab.

Fix #4: Update the Network Adapter Driver.

An outdated or corrupted network adapter driver can keep your WiFi from turning on. But it isn’t really a major cause of frustration since updating it can be done in a jiffy. Even better, you have two ways to do so: manual or automatic.

The Manual Method

You can manually update your network adapter driver by visiting the website of your hardware manufacturer and searching for the most recent driver release for your network adapter. However, if you prefer the manual approach, make sure that you select the driver that is compatible with your hardware and your Windows 10 version. 

The Automatic Method

If you are not that techy or you simply don’t have enough time to update your network driver on your own, you can use a third-party tool or utility. With this option, you don’t necessarily need to know what operating system your computer is running. You don’t even need to worry whether or not you are installing the correct driver because the tool does it all. Just make sure that you download and install a legit and trusted driver updater to ensure you don’t get into trouble in the process of updating.

Fix #5: Uninstall and Reinstall the Network Adapter Driver.

If the previous fix did not work, try to uninstall and reinstall your network adapter driver. Check if it resolves your WiFi connectivity issue.

Here’s how to do it:

  1. Into the Search bar, type Device Manager.
  2. Hit Enter.
  3. The Device Manager should be open now. Navigate to the Network Adapters section and expand it.
  4. Right-click on WiFi Network Adapter.
  5. Click Uninstall Device.
  6. Hit the Uninstall button.
  7. Restart your Windows 10 computer. Your computer will automatically install a driver that is compatible with your network adapter.

Fix #6: Run the Network Adapter Troubleshooter.

Your Windows 10 device has a built-in network adapter troubleshooter in case you encounter WiFi connectivity issues. Run it to fix the problem.

Simply follow these steps:

  1. Into the Cortana Search bar, input troubleshoot and hit Enter.
  2. Select Internet Connections.
  3. Choose Run the Troubleshooter.
  4. Go to Network Adapter and choose Run the Troubleshooter.

Fix #7: Perform a Quick System Restore.

If your WiFi still does not turn on, we suggest that you perform a system restore at this point. By doing so, you can return your system settings and files to a certain point when your WiFi network still works properly.

To perform a system restore, follow these steps:

  1. Into the search box, input recovery.
  2. Hit Enter.
  3. Click the Open System Restore button.
  4. Select a restore point and hit Next.
  5. Check the box next to the Show more restore points option. Here, you should see a list of saved restore points. Think of a date when you were still able to connect to a WiFi network.
  6. Hit Next and click Finish.

Fix #8: Turn Off the Firewall Temporarily.

Sometimes, your firewall software prevents you from connecting to a WiFi network. You will know if the connection problem is caused by your firewall by turning it off temporarily and trying to visit a trusted website.

The process of switching off a firewall depends on the software you have installed. To be sure, you might want to check the documentation of your firewall software first to learn how to switch it off.

Below is a general way to switch off a firewall:

  1. Into the Cortana search bar, input Command Prompt.
  2. Press Enter and wait for the Command Prompt button to appear.
  3. Click Run as Administrator, which is next to the Command Prompt button, and select Yes.
  4. Into the command line, enter netsh advfirwall set allprofiles state off.
  5. Hit Enter.
  6. Open your favorite web browser and visit a trusted website to check if the problem persists.

If you confirm that the firewall software is causing the WiFi issue, contact the software manufacturer right away. An expert from their team might work with you to suggest possible fixes. 

Note: After checking if the firewall is the culprit behind your WiFi problem, be sure to turn it back on right away. Not switching on your firewall may cause your computer to be vulnerable to worms, viruses, and other malware entities.

Fix #9: Turn Off the Antivirus Software Temporarily.

There are times when your antivirus software keeps you from getting connected to a WiFi network. And just like a firewall, you can temporarily switch off your antivirus to check if it is the reason behind your WiFi problem.

Now, if you do not know what antivirus program is currently installed on your Windows 10 device, do the following:

  1. Into the Cortana search bar, input System and Security.
  2. Hit Enter.
  3. In the window that opens, select the Review your computer’s status and resolve issues option.
  4. Click the arrow next to Security.
  5. If Windows 10 can detect the antivirus software currently installed on your device, it will be listed under Virus Protection. 

Note: Be sure that you switch on your antivirus as soon as you confirm whether or not it is causing the WiFi problem. This way, you can keep your computer protected while browsing.

Fix #10: Clean Your Windows 10 Computer.

There is a chance that junk and unnecessary files are keeping your computer from connecting to a WiFi network. To keep these files from giving you technical headaches, make sure to get rid of them every now and then.

Sure, you can erase them manually. You may check all your folders for any suspicious and unnecessary files and delete them. But take note that this can be risky, especially if you are not familiar with all the files saved on your computer. Deleting an important system file may only cause more problems, and we don’t want that to happen.

For that reason, we highly recommend installing a reliable PC repair tool. With such a tool, you can just run a quick scan and let it do the job of finding unwanted files.

Wrapping Up

With all the obvious reasons, it’s probably safe to say that the internet is one of the greatest gifts of modern technology. It comes as no surprise why when we cannot access it, we become anxious and frustrated.

Lucky for us, there are many possible fixes we can try. We have even listed ten above. Hopefully, one of them has helped you resolve your WiFi not turning back on issue.
