You only need pakage firmware-iwlwifi; you need a system (a linux would be nice) with internet connection.

wget -c http://ftp.us.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-iwlwifi_20210315-3_all.deb

Install the package with dpkg directly.

sudo dpkg -i firmware-iwlwifi_20210315-3_all.deb

Then you can load the modul again.

sudo modprobe -rv iwlwifi
sudo modprobe -v iwlwifi
