I have a Thinkpad T470 with Intel Dual Band Wireless AC(2x2) 8265.
On Debian testing, and firmware-linux-nonfree and firmware-iwlwifi are installed.
lspci output does not show the network adapter

I booted up a live usb with non-free firmware, and that too did not show me the wireless adapter.
What could be the problem here? Did my hardware randomly die?
