Intel WiFi6 AX201 160Mhz not working in Ubuntu 18.04

Good evening,

 

I have just installed Ubuntu 18.04 LTS on my new notebook MSI Katana gf66 but a lot of harware is not working including Wifi.

 

I am posting some outputs that I hope can be useful:

 

uname -r
5.4.0-135-generic

 

sudo lshw -c network

Here should be seen the kernel drivers used (that should be iwlwifi) but instead the output shows Interrupt: pin A routed to IRQ 255

 

lsmod | grep iwlwifi

no output

 

I installed the module iwlwifi and iwlmvm with sudo modprobe iwlwifi and sudo modprobe iwlmvm and now lsmod | grep iwlwifi shows

iwlmvm 385024 0
mac80211 856064 1 iwlmvm
iwlwifi 339968 1 iwlmvm
cfg80211 712704 3 iwlmvm,iwlwifi,mac80211

 

dmesg | grep iwlwifi

no output neither before nor after installing the iwlwifi module

 

Still anything working, I don't know where to put hands.

Thank you in advance for the support,

Guido
