How to reinstall Qualcomm Atheros wifi driver

If you noticed your wifi stopped working, or you accidentally or purposefully uninstalled your Qualcomm Atheros wifi driver, you may need some help to make everything go back to normal. We provide you with several solutions to fix your Qualcomm Atheros wifi driver issues.

If your Qualcomm Atheros wifi driver stopped working, or you accidentally uninstalled it, you can try one of the following solutions.

Contact your device manufacturer

It is the safest and easiest solution. Because Qualcomm does not offer driver downloads, you need to contact your device manufacturer depending on your computer device brand (for example, Dell or Sony). Then, go to your device manufacturer's official website and either find the proper driver or ask for help from the support team.

The subsequent solutions involve commands specific to Windows, but you can find out how to achieve the same result on any other operating system.

Disable and enable your Qualcomm Atheros wireless driver
