Bug#989777: Severity: High / Debian 10 & 11 with Kernel 5.10.x-amd64 => Intel AX210 Wifi & Bluetooth not work

[pham...@bluewin.ch]

Hello and thank you for your message.
I'm already using the "non-free" Debian images which contain firmware for 
network cards etc.
https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/weekly-builds/amd64/iso-dvd/
The package "firmware-iwlwifi_20210315-2_all.deb" is correctly installed, but 
my Intel AX210 Wifi / Bluetooth card is not recognized and is not functional.
This problem is extremely debilitating for me (severity: high). I bought this 
hardware to run on Debian 10 with Backport and on Debian 11 but I cannot use it.
Best regards.
Philippe
