Does it mean that your Intel wifi card is a USB one?

Perhaps you do not need to download deb files manually. Ensure that your 
/etc/apt/sources.list contains the non-free-firmware repository and try 
as root

apt update
apt install firmware-iwlwifi

however you may need a newer file than packaged for bookworm.

Exact messages (e.g. from "journalctl -b") output may help to solve your 
issue.
