A good network connection is very important because a lot of work depends on a stable Internet connection. There can be several reasons why your connection is not working properly, and they can be easily fixed.

Why the Wi-Fi adapter is not working in Windows 10

Generally, one of the most common problems after installing an update is related to the network connection. For example, low speed, unreliable or complete loss of connection with a wireless or wired connection, which leads to problems connecting to the Internet and network resources such as printers and shared folders.

While system updates are designed to fix problems and improve the user experience, it is not uncommon for faulty updates through Windows Update to cause connectivity problems. If you suspect that a recent update is causing network problems, you can remove it to alleviate the problem until a new update arrives.

Sometimes an older version of a network driver can cause compatibility issues with a Windows 10 update. You can usually solve this problem by updating the driver to the latest version.

Regardless of the reason, if your device can’t connect to your local network or the Internet after a recent Windows 10 update, Microsoft recommends several ways to solve the problem.

In this Windows 10 guide, we’ll show you a few ways to fix the “WiFi adapter not working in Windows 10” problem.
