Hi, I have an Ubuntu 20.04 LTS machine for a while, and suddenly one day my wifi stopped working. Here are some photos from the settings and GNOME network display:

I've looked everywhere, tried a lot of solutions but it didn't work. I've also followed some of the post related to this issue in the past in this community. And I think some of the output here would be useful. I have no clues whatsoever on how to fix this, any help is really appreciated:

Here is the kernel version:

 

 

mnguyen@mnguyen-xps-13-7390:~$ uname -r
5.15.0-41-generic

 

 

Here is the nmcli messages, showing I'm missing some plugins, but I don't know which one and also my wifi is 'unmanaged'

 

 

mnguyen@mnguyen-xps-13-7390:~$ nmcli
wlp2s0: unmanaged
        "Intel 6 AX200"
        wifi (iwlwifi), plugin missing, hw, mtu 1500

 

 

 Here is the dmesg
