Intel microcode updates via system updates are nothing to do with the
BIOS/EFI Firmware.  Google for your mother board to find the latest
version and how to update.

Irrelevant, there are often bug fixes that can affect this sort of
issue, and are not necessarily documented in the bios release notes.

OK, I thought you might have meant hardware/software issues rather
than spec changes.

You haven't said the results of running live 16.04 on the machine.
Also would be interesting to run 18.04 live on the one's that do find
the access points.
