Updating kernel from 6.5.0-4 to last 6.5.0-5 on Debian testing it made the wifi card not showing on my laptop.
To solve this issue i checked on /etc/modprobe.d/iwlwifi.conf and inside there was the following line: options iwlwifi enable_ini=N (this line was a workaround for an old bug).
Simply comment the line or delete the file and reboot the machine.
After reboot, driver will be normally loaded and wifi will work!
