I put my .ucode file in /lib/firmware folder. On boot Debian write me:

I can't enable WiFi. enter image description here Download driver from git.kernel.org (I need reputation to post more than 2 links)

Big thanks for your response!

This is typical for the std deb kernel, it will look for a version and fail to load it until it finds a valid one and it will load that one.

for example in my log file;

Oct 23 16:39:43 mike-laptop4 kernel: [ 7.432898] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-7265D-24.ucode failed with error -2 Oct 23 16:39:43 mike-laptop4 kernel: [ 7.432921] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-7265D-23.ucode failed with error -2

(I have iwlwifi-7265D-22.ucode but not 23 or 24 in my firmware directory)

so, for some reason if your wifi is not loading it's not finding the correct firmware version.

I'd suggest checking kernel wifi for a firmware download.

https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

you can run lspci to check your wifi chip, then you can download the appropriate firmware blob based off your kernel version and wifi card.

also there are some good tips there regarding power management.
