10 Best Ways to Fix Wi-Fi Adapter Not Working on Windows

While we always recommend an Ethernet connection to Windows PC users, it may not be convenient for everyone. If you want to set up a wireless connection on Windows PC, get a USB Wi-Fi adapter from the local shop or Amazon. But what if the USB Wi-Fi adapter fails to work on your PC?

When our Windows PC’s Wi-Fi adapter stopped working, this trick worked like a charm for us. It’s time to change the Wi-Fi adapter value from the Device Manager menu.

Step 1: Launch the Device Manager menu (check the steps above).

Step 2: Right-click on the Wi-Fi adapter and open Properties.

7. Disconnect Other Devices

Did you connect several devices to your PC? It may create interference with the Wi-Fi adapter function. You should remove other devices and try again. You can always connect your keyboard and mouse wirelessly to the Windows PC.

8. Get a New USB Adapter

You can try connecting the Wi-Fi adapter to another PC. If the issue persists on all the devices, the Wi-Fi adapter is the main culprit here. It’s time to get a new Wi-Fi adapter for your workstation. We recommend getting a Wi-Fi adapter that supports dual-band Wi-Fi.

9. Restart Router and Update the Firmware

Do you have Wi-Fi issues on all the connected devices at home or office? It’s time to troubleshoot the router.

Rebooting the router is one of the best ways to fix network issues at home or office. You can remove the router from the power plug, wait for around 30 seconds, and plug it back in.

If the issue persists, you need to update the router firmware to the latest version. You can read Asus and TP-Link’s dedicated guides to complete installing the firmware update. Both companies are well-known in the router market.

10. Setup an Ethernet Connection

Nothing beats a dedicated Ethernet connection on a PC. It offers robust, no-nonsense, high-speed internet speeds to your PC. You can seamlessly update Windows and download large files, games, and more without missing a beat or running into errors. You should ditch the Wi-Fi adapter and get help from a professional to establish the Ethernet network at the home or office.
