The Intel Atom X5-Z8350 is a SoC (system on chip) – it does not include built-in WiFi on the CPU itself. WiFi is provided by a separate chip on your device’s motherboard.
Common modules used with this Atom include:

You need the driver for that specific WiFi chip, not just the Atom CPU.

From the device manufacturer (best option)

If no manufacturer support exists

Are you trying to upgrade a Z8350 device to Windows 11? Stop. Or at least, proceed with caution.

The Atom x5-Z8350 is not supported on Windows 11. While you can bypass the TPM check, the driver architecture is different. Many users find that even with the correct drivers, the Wifi on a Z8350 is unstable on Windows 11.

The Solution: Stay on Windows 10. Microsoft supports it until October 2025. Trying to force this aging chip to run a newer OS is often the reason your Wifi stopped working in the first place.
