I put the M.2 WiFi adapter back in that the machine shipped with, and Linux can’t see that either.

I’m now wondering if, as I never used it in the past, I’ve disabled it in the BIOS (and forgotten about it), and that’s also affecting the new NIC? 🤔

I’ll need to find a monitor and keyboard for this machine, and see what the BIOS says…

It’s supposed to have Bluetooth, too, which also isn’t showing. I suspect I disabled all this when I was running ESXi on it in the past…

*edit* ah, no, my mistake: Bluetooth is hung off USB, not PCI, so shows up with lsusb 🙄

But then that’s really odd, as the Lenovo spec sheet suggests these devices have an integrated WiFi+bluetooth combo device 🤔

So this video shows someone doing the same as me with almost identical hardware:

Interestingly, someone in the comments seems to be having the same problem, and notes that they'd previously turned wifi off in the BIOS. Encouraging!

I'll have to get at the BIOS when I get chance...
