Problem: Wi-Fi will not show in network settings, only wired.
Question: how do I make it to show?
**EDIT: see last post in this forum for solution: viewtopic.php?f=90&t=273099&start=20#p1501349 **
I looked around in this forum and in the internet, and I think the information below is useful. I suspect I need to install a driver for the wireless network adapter (Realtek) but I don't know how to do that (or if I am correct, in which case, would you point me to installation instructions?). I must add, bluetooth does show and audio is working fine.
Please see "Supporting info" section after code outputs to learn why I suspect the problem is a missing driver.
I will very much appreciate your time and effort spent in finding this answer.
Jorge.

My problem seems to have a diagnostics very similar to the one described in the following post (but I haven't tried their solution because their culprit is different from mine)
https://www.linuxquestions.org/question ... 175630496/
The site below gives instructions to install drivers (but maybe that is not my problem?)

The fix proposed in the link below will not work for me because wireless LAN doesn't even show in rfkill list all

The fix by JeremyB in the post below (sudo apt install linux-modules-extra-4.15.0.24-generic) didn't work for me, I even tried booting into all previous kernels that I have access to through grub (4.15-0-24, 4.15.0-23, 4.15.0.20, all generic).

One last option again by JeremyB which I am willing to consider if everything else fails:
