Hi I've been struggling with this for several days now

I have a PC that i'm dual booting with Windows 10 and Ubuntu 20.04, the Window's 10 OS is working fine, however I've had massive issues with getting wifi working on my Ubuntu OS.

Mobo: Gigabyte X570

Wificard: Intel AX200

I first started with ubuntu 18.04 but was unable to get the wifi to work after several days of trying different solutions, one answer said they were able to solve the problem by switching to a newer distro, so I decided to try 20.04

The first time I installed 20.04 the wifi worked during installation so I thought everything was fine, however after install was completed the wifi no longer worked. I have since uninstalled and then reinstalled 20.04 however wifi no longer works during installation.

secureboot is disabled rfkill list gives no response sudo modprobe iwlwifi gives no response sudo modprope -r iwlwifi gives no response

 ubuntu@ubuntu:~$ sudo dmesg | grep iwlw
[  123.575129] iwlwifi 0000:05:00.0: enabling device (0000 -> 0002)

fixes tried on 18.04: -copying firmware file downloaded from intel website into firmware directory -kernel was 5.3, the newer kernel solved the problem for some people -backport iwlwifi package, i can't remember what exactly this was a couple of days ago, but i remember messing with this

Followed chili555's recommendation, disabled fast boot on my Windows OS, and then wifi card was recognised and working! I couldn't figure out how to set their comment as the answer, and I just wanted to make it clear for anyone looking at the question how this issue was solved. Thanks chili555!
