I'm trying to go back to Debian, but I can't get wi-fi to work.
First I tried the stable version, but my wi-fi, graphic cards, bluetooth were not working, I had problems with kernels 4.anything in the past with others distros too, so I know my hardware really needs newer kernel to work, version 5.anything or superior
With that in mind and after trying the stable version just to be sure It was not really work out-of-the-box I decided to go with backports to new kernel version, that failed to provide me wi-fi, so I did a new fresh install on gnome-box vm, I did the following steps/trials so far:
1 base install (nothing selected on tasksel)
2 added "bullseye main contrib non-free" instead of "buster main" (commented out the updates and security repos, I kept just the base)
3 apt update && apt upgrade
4 reboot
5 apt install gnome-core
6 apt install firmware-iwlwifi
7 Downloaded the Intel® Wireless-AC 9560 firmware https://wireless.wiki.kernel.org/_media ... 8819.0.tgz - added iwlwifi-9000*.ucode inside /lib/firmware
8 apt install firmware-linux-nonfree
9 Restarted again, still no wi-fi
What should I try or do next to solve this problem?
