How to Fix Wi-Fi issues on Windows 10 21H1

To solve Wi-Fi related problems on Windows 10, apply these workarounds one after another –

1] Fix Wi-Fi issues by troubleshooting Network Adapter 

Microsoft provides an inbuilt troubleshooting tool in the Settings app that may fix commonly occurring wireless or other issues on Network Adapters automatically. To troubleshoot then, use these steps –

  • Press Window + I to launch the Windows Settings.
  • Select Update & Security.
  • On the left column, click the Troubleshoot option.
  • Jump to the right side and click over the link – Additional troubleshooters.
  • Scroll down and hit Network Adapter.
  • On its extended pane, click the option – Run the troubleshooter.
  • When this tool prompts to choose a network adapter that you want to troubleshoot, tick the Wi-Fi radio button and hit Next.
  • Now, wait for this tool to scan and resolve the underlying causes.
  • After the troubleshooter fixes the Wi-Fi problem on your computer, restart your PC.

2] Reset Network Adapter

If the Wi-Fi issue persists even after running the above troubleshooter, you should try resetting the Network itself. By Network reset, we mean removing the Wi-Fi connection first and then reinstall it back on your computer. Performing so will restores the default settings and thus may fix the Wi-Fi slow speed issue on Windows 10. Here’s how to perform this task –

  • Right-click on the Windows icon and select Settings.
  • Proceed as follows – Network & Internet > Status.
  • Head over to the right side and click Network reset. See the Snapshot below –
  • On the succeeding screen, hit the button – Reset now.
  • If any confirmation message prompts, click Yes.
  • Let the network reset and when it does reboot your device.

Note: Performing a network reset will remove all VPN clients from your computer. So, you need to reinstall such apps on Windows 10 21H1.

3] Update Network Adapter

In the case that you’re still encountering slow Wi-Fi speeds, go and check if this problem is occurring because of an outdated driver or not. At times, network adapter becomes obsolete and thus prohibits users from accessing the internet on their computers. Here’s how to update Network adapter –
Step-1: Click on the Start button. Type “Device Manager” and double-click over the top result.
Step-2: Locate Network adapters and click the “>” icon left of it. Put a right-click on the Wi-Fi adapter, and hit Update Driver.
Step-3: Hit “Search automatically for updated driver software” and let the system installs pending updates on your device.
Note: If there isn’t a new update for the network adapter, visit the manufacturer’s official site, and see if they are providing any beta or latest patch of that adapter. If you do find any update for the driver, download it on your device. Now, re-follow the above steps and hit “Browse my computer for driver software” in step-3.
Step-4: Hit the Browse option and navigate to the download folder which contains the downloaded setup file.
Step-5: Mark the Include subfolder option and press the Next button.
On completing the above steps, you should be able to connect to the Wi-Fi network.

4] Rollback Windows 10 21H1

If you’re still experiencing wireless connectivity problems, you might have installed a buggy update on your device. In such a scenario, just rollback Windows 10 21H1 if you had upgraded your operating system and still have access to the Windows.old folder. For users who have clean installed May 2021 Update, they must uninstall it from their PCs. After either performing a rollback or an uninstall, make sure to pause Windows 10 21H1 update, so that it doesn’t get activated automatically.
