After some update and then crash (the origin story is blurry), the wifi was gone. I was then on Ubuntu 20.04 but did a clean reinstall with Debian with the non-free firmwares.

Nonetheless the problem persisted. I read every question I could on the Internet but so far no luck. So:

  • Clean reinstall with Debian 10 and then move to bullseye
  • firmware-iwlwifi and firmware-misc-nonfree are installed
  • Network card seen with lspci: Network controller: Intel Corporation Cannon Point-LP CNVi
  • No soft/hard block (check with rfkill)
  • ifconfig only shows the ethernet and the loopback interface
  • dmesg | grep iwlconfig:

Note: there is a weird issue with the bluetooth, dmesg | grep blue:

And I can't find that version of the firmware online.

Any help would be appreciated. Thank you very much.

  • Could you add the output of lspci -knn |grep Net -A3 and uname -a. Please.

Looks like a Kernel bug that got fixed very recently and might be included in Kernel 5.7.8, easy solution is to use a less recent Kernel (>v5.7).
