MediaTek — MediaTek Wi-Fi 6 driver (MT79xx family)
When blamed in a crash: Very likely the true cause
What to do
MediaTek's Wi-Fi driver, shipped by laptop makers (also branded AMD RZ-series) — a well-known BSOD source on older versions.
- Download the newest Wi-Fi driver from your laptop/PC maker's support page (MediaTek doesn't publish end-user drivers).
- AMD RZ600-series adapters: AMD's driver page also carries updates.
- If crashes continue, a cheap USB Wi-Fi adapter is a practical workaround while the vendor fixes it.
