I have no idea what this means, sorry. Searches only seem to turn up
fairly old hits.

Is it possible that Windows is installed in UEFI mode (it almost
certainly is) and Ubuntu was installed in BIOS/CMS/Legacy mode? If that
is the case, the easiest solution is to reinstall Ubuntu in UEFI mode.
Alternatively, set the UEFI firmware to boot in CMS/Legacy mode to
start Ubuntu, and install grub-efi. See [1] for a ton of information on
this. You will need to mount the ESP[2] on /boot/efi before you install
grub-efi, though.

What does lcpci say about the wifi chipset?

Again, [1]. There is probably an equivalent page on the Ubuntu wiki,
but the Arch wiki tends to provide a lot of technical information that
can be helpful but is often left out of Ubuntu wiki pages.
