I agree that there is no wifi adapter visible. This is not a driver matter, since it first needs to detect the wifi card before a driver can be loaded. I think it's probably a hardware failure. Please check if the card inside the laptop (likely a Mini PCIe card) is properly inserted.
The person from the previous topic had an Atheros wifi card visible in inxi -Gx output, which you don't have. You have an Atheros chip, AR8121/AR8113/AR8114, but that is the wired ethernet.
martka had an AR8152 v2.0 for the wired ethernet, so that must be a different laptop than yours. I suppose your laptop is a bit older than the 1015BX of martka.
