What to Do in Case You Can’t Find a Wi-Fi Connection After a Windows 10 Upgrade

There are actually 2 main reasons why Wi-Fi becomes unavailable after upgrading to Windows 10:

1.      The Wi-Fi or wireless adapter driver is not updated and is therefore not compatible with Windows 10. In most cases, the Wi-Fi driver is missing after the Windows 10 update.

2.      The problem may also be because of the triggering of unsupported VPN software present during the Windows 10 upgrade. If the PC is still using an old VPN client, specifically Cisco VPN client or Sonic Global client, it’s certain that this piece of software is what is causing the no Internet connection issue. Thus, uninstall the VPN software.

There are 2 major solutions to fix Windows 10 if Wi-Fi is not available:

1. Update Wi-Fi Adapter Drivers on Windows 10

To resolve the Windows 10 Wi-Fi availability issue, the first method should go to the wireless driver to match with Windows 10. The driver for the previous Windows 8.1 or 7 is not compatible with Windows 10 and it may have removed the driver during update. Therefore, fix the Wi-Fi driver with a Driver Talent tool. It can help to check if the Wi-Fi driver causes the problem and then update the driver either by repairing it or downloading the latest one to match the wireless adapter for Windows 10.

You can also try the network version: Driver Talent for Network Card. This version can help to fix the driver without Internet connection. You should install this tool before updating to Windows 10. Alternatively, download it with an available computer that has Internet connection and move it to your computer to install network driver offline.

Some users may have installed the Wi-Fi driver but the Windows 10 Wi-Fi keeps disconnecting. This is because the driver you installed can’t work properly on your computer. Try Driver Talent to install the Windows 10 Wi-Fi driver to work so that it can work properly.

Download and install Driver Talent on your laptop or desktop computer to solve your Windows 10 Wi-Fi issue.

2. Uninstall the network adapter driver and restart

If the above didn’t work, try to uninstall the network adapter driver, and then restart your computer and have Windows automatically install the latest driver. Consider this approach if your network connection stopped working properly after the recent update.

Before uninstalling, make sure you have drivers available as a backup. Visit the PC manufacturer’s website and download the latest network adapter driver from there. If your PC can’t connect to the Internet, you’ll need to download a driver on a different PC and save it to a USB flash drive, so you can install the driver on your PC. You’ll need to know the PC manufacturer and model name or number.

In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.

In Device Manager, select Network adapters > the network adapter name.

Press and hold (or right-click) the network adapter, and then select Uninstall > Delete the driver software for this device check box > OK to confirm you want to uninstall it.

After uninstalling the driver, select the Start button > Power > Restart.

After your PC restarts, Windows will automatically look for and install the network adapter driver. Check to see if that fixes your connection problem. If Windows doesn’t automatically install a driver, try to install the backup driver you saved before uninstalling.

And if all else fails, you can always call your friendly tech support company.
