Check if your firmware is in /lib/firmware/rtw88/ and not in
/lib/firmware/

This is what I have

# ls -l /lib/firmware/rtw88/
total 740

If you need a missing firmware, instead of getting it from ubuntu, get it
from the source :)

> I'm not seeing an updated realtek firmware in backports:

Here I have this one

# dpkg -l firmware-realtek
ii  firmware-realtek 20240709-2~bpo12+1 all          Binary firmware for Realtek wired/Wi-Fi/BT adapters

To install it you can try (after adding backports to sources)

apt -t bookworm-backports install firmware-realtek
