Original Question:
Having worked fine with 22.04 for a couple of years, my Wi-Fi stopped working a week or so ago (I assume due to an update, I'm not sure). I attempted an upgrade to see if newer drivers would help but it didn't go well, and I ultimately started over with a fresh 24.04 (wiped hard disk). But the Wi-Fi still doesn't work - wireless settings UI shows No Wi-Fi Adapter Found.
I tried making sure the Realtek device had an appropriate driver, installing r8168-dkms but it didn't help - so I'm not certain whether it's functioning correctly. But to me, looking at the inxi an lshw output, the Intel device looks more like it's in a bad state.
$ uname -r

$ iwconfig
lo no wireless extensions.
enp4s0 no wireless extensions.
