So I've recently switched from Manjaro to Debian and I've been working with it on my desktop pc for a while now. Now I decided to change my laptop from Manjaro to Debian as well however there seems to be some kind of issue with the WIFI.

I've read through a few sources and tried everything from making sure there is only one networkmanager installeld, changing NetworkManager.conf manged to true.

Latop: XPS 15 7590

lspci -nnk | grep 0280 -A3:

3b:00.0 Network controller [0280]: Intel Corporation Device [8086:2723] (rev 1a)
Subsystem: Bigfoot Networks, Inc. Device [1a56:1654]

According to linux-hardware the the new wifi card should work under linux kernel 5.7 and newer. It can be achieved by installing the kernel from buster-backports.

printf "%s\n" "deb http://deb.debian.org/debian stretch-backports main" |\
sudo tee /etc/apt/sources.list.d/buster-backports.list
sudo apt update
sudo apt install -t buster-backports linux-image-amd64

Download the Intel® Wi-Fi 6 AX200 160MHz and follow the install instructions:

wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi/iwlwifi-cc-46.3cfab8da.0.tgz
tar xvf iwlwifi-cc-46.3cfab8da.0.tgz
cp iwlwifi-cc-46.3cfab8da.0/* /lib/firmware

Then reboot and disable the secure boot.

sudo reboot
