It's becoming clear that Microsoft is having a quality control problem when it comes to updating Windows 10. On September 10, the software giant began the rollout of update KB4515384 for devices running the May 2019 Update (version 1903), and shortly after the release a number of users started reporting problems with the Start menu and search, followed by audio issues with certain games, and now, it appears that the update has a bug affecting network connectivity.

According to several reports on Reddit and Microsoft forums (via Neowin), after installing update KB4515384 on Windows 10, some wireless network adapters will stop working, and reinstalling the latest device driver doesn't fix the problem.
