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

An update commonly causes problems with a network connection, which is one of the most common problems. It’s possible to experience problems connecting to the Internet and printers and shared folders if your wireless or wired connection is low speed, unreliable or completely lost.

It is not uncommon for faulty updates through Windows Update to cause connectivity issues, despite the fact that they are supposed to fix problems and improve the user experience. You can eliminate a recent update from your system if you suspect it is causing network problems until another update is released.

Updated network drivers usually solve compatibility problems caused by older network drivers and Windows 10 updates.

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.

It is recommended that you restart your computer if there is a new driver found by the system.

It is recommended to purchase a new WiFi adapter or use a USB wireless adapter instead if there are no problems with Windows services or network drivers. In Windows 10 Creators Update, the tiny “dongle” can be easily plugged into any standard USB port. Plugging in the USB wireless card will install the driver, then you find it on your computer. Just connect to your WiFi network and enjoy your experience.
