My WiFi adaptor has disappeared!

I have had this working via updating to a newer kernel version than was provided with 20.04 (am currently on 5.11.12) which I believe should support the bundled card - and it had been working without issue. However a couple of days ago it seems to have gotten lost after some updates, and now isn't even shown in the bios. Have tried a firmware reinstall and bios update to no avail.

I'm expecting to see this:

sudo lspci -nn | grep Qualcomm
6c:00.0 Network controller [0280]: Qualcomm Device [17cb:1101] (rev 01)

as described in but the device isn't showing up any more.
