WiFi adapter neither connects nor detects networks. Intel AX200

[Nkolot]

After searching and trying all kind of things found on Internet I decided to ask a question.

First of all I want to say that I've instaled the following backport-iwlwifi and firmware because the wireless adapter was unclaimed. The wlp1s0 is now no longer unclaimed. Ethernet Internet connection works fine.

https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release#components

Although now I can see the interface using ifconfig I can't detect any wireless Network on my wicd network manager.

Spoiler: ifconfig

I will put below different outputs from commands that may help you understand what the problem is.

The first interface was Unclaimed at first. It is strange to me to be described as an Ethernet interface. sudo lshw -C network

1) Have you rebooted to make the wifi work?
2) What distro are you using?
3) What is the output of the Terminal command: lspci |grep Network
4) What is the output of the Terminal command: lsusb

Thank you for your answer.

I've instaled the following backport-iwlwifi

Install: firmware-iwlwifi
instead
from Repository.

Install: firmware-iwlwifi

from Repository.

I've installed following these instructions https://wiki.debian.org/iwlwifi, but nothing seems to work. It was the first time I did before reading this and knowing that a backport is necessary because of my Kernel version (4.19.0-8-amd64).
Any ideas?

 

[Nkolot]

I've installed firmware-iwlwifi and nothing seems to work. I've forgotten to say that when I installed the backport-iwlwifi the following Warning appeared, missing "System.map".

Note:
You may or may not need to update your initramfs, you should if
any of the modules installed are part of your initramfs. To add
support for your distribution to do this automatically send a
patch against "update-initramfs.sh". If your distribution does not
require this send a patch with the '/usr/bin/lsb_release -i -s'
("Debian GNU/Linux") tag for your distribution to avoid this warning.

Your backported driver modules should be installed now.
Reboot.
