According to Microsoft’s support announcement, the company has now blocked some PCs with Qualcomm wireless network card devices from upgrading Windows 10 Version 1909. This problem is mainly caused by the incompatibility of the wireless network card drivers used by some users. After upgrading Windows 10 Version 1909, the wireless network may not be able to connect properly. Therefore, Microsoft directly prevents users from upgrading. Unless the NIC driver problem is solved first, the easiest way to solve this problem is to upgrade the NIC driver directly.
Microsoft said it has blocked users from upgrading through the Windows 10 Update Assistant, the Windows 10 Media Creation Tool, and the Windows 10 Installer. When users try to upgrade using these tools, they will see the following prompt: Your computer driver does not fully support this version, and a new version is available.
The user clicks on the more information below the prompt to jump to the Microsoft support announcement page, and the user can follow the Microsoft solution to solve the driver problem. Workarounds include downloading a new version of the driver directly through the system update feature or manually updating the package through the device manager.
It is recommended that the user check the new version of the driver directly through the system update function. If the update is checked, the Qualcomm NIC driver can be found. After installing the new version of the driver, it is recommended to restart the system and then perform the upgrade again in various ways.
If you are not offered the driver from Windows Update, we recommend you try the following steps:
- Select Start or the search box in the task bar.
- type “device manager” and open Device Manager.
- Within Device Manager, find Network adapters and expand it to see all the currently installed adapters.
- Right-click or long press on the Qualcomm adapter and select Update driver.
- Select Search automatically for updated drivers on the dialog that opens.
- Wait for it to complete the task. If it says, “The best driver for your device are already installed.” then the driver was not updated. If the driver was updated, you should now be able to Check for Updates and install the newer version of Windows 10.
