quick kernel
After upgrading from LMDE6 to LMDE7 on my notebook, the firmware-iwlwifi driver ceases to work after notebook wakes up from sleep or even after boot after proper shutdown. The only fix i've found is reinstalling the package (which is sometimes a problem without internet)
Anyone else experiences this? How can i debug this further?
The laptop is Dell precision 3570 with Intel Alder Lake-P PCH CNVi WiFi device.

.. etc for all versions from -89 to -77 and then:

how come the firmware works on first reboot, but not after all the reboots after that one

check if you have these files
find /lib/firmware/ -name iwlwifi-so-a0-gf-a0*

What result for cat /proc/cmdline

let me try to reinstall now if new drivers appear

huh... what does
apt policy linux-firmware
say?
quick kernel
nothing
gloomy pewter
Oh, you're on lmde, not regular mint
quick kernel
yes
gloomy pewter
then, what does
apt search firwmare
says?
quick kernel
a lot of stuff, what are you looking for specifically?
gloomy pewter
can you copy all of it?
quick kernel
gloomy pewter
Ok.... let's try like this:
sudo apt update
sudo apt install -y apt-file
sudo apt-file update
apt-file search iwlwifi-so-a0-gf-a0-77
plain vine
Is this a normal install?
gloomy pewter
This should do it, download the file and run
sudo cp Downloads/iwlwifi-so-a0-gf-a0-89.ucode /lib/firmware/
sudo update-initramfs -u
then restart and confirm with
dmesg | grep iwlwifi
P.s. if your downloads folder is named differently correct the first command accordingly
quick kernel
Ok.... let's try like this:
sudo apt update
sudo apt install -y apt-file
sudo ...
this gave me empty output
so, thefirmware files i was missing disappeard again, even without restart
there's some kind of cronjob or something deleting the files. I noticed they do have newer dates than the rest of them
quick kernel
This should do it, download the file and run
sudo cp Downloads/iwlwifi-so-a0-gf...
this did nothing
ok found it
there indeed is a cronjob copying drivers from /opt to /lib/firmware
i have no idea where is it from, the timestamp is 29.8.2021
mh, ok this is probably it https://github.com/Rongronggg9/drivers-linux-firmware
alright, problem solved, guess this was my fix for the wifi back when it was not supported by lmde yet
