If your computer uses a partial lyno Qualcomm Wi-Fi adapter, it cannot be updated to Windows 10 November 2019 Update (the latest version of the operating system), and Microsoft says it has placed an upgrade blocker that will prevent you from installing Windows Version 10 1909, version 1903, or even 1809. This is because the older Qualcomm Wi-Fi adapter causes problems with the Wi-Fi connection on Windows 10.
At the same time, this update blockflag prevents the upgrade process on the Update Assistant and Media Creation tool to be blocked.
Microsoft recommends that users manually check for updates and install new Qualcomm drivers when they are available. Theoretically, if you install a new driver, you should be able to update to Windows 10 version 1909.
If you’re using an older driver and Windows Update can’t provide updates, you can try updating the Wi-Fi driver manually:
Open the Start menu and search for Device Manager.
Click Network Adapters in Device Manager to see all the installed adapters.
Right-click the Qualcomm adapter and select Update.
Allows Device Manager to automatically search for updates and then wait for it to complete the process.
If you can follow the steps above to update the driver, you can. However, if you are still running the older driver and you cannot get any updates through Device Manager, you will need to install the driver manually, which is a complex process.
