This important part for ax201 and ax200
setup of wifi interface
create an interface for wifi networking. Good examples of manually setting up a wifi network. Use this to help you overcome problems if NetworkMgr does not automatically setup your wifi network.

The config in rc.conf was wrong. It should have been

wlans_iwlwif0="wlan0"
ifconfig_wlan0="WPA DHCP"

Then I created a wpa_supplicant.conf file with router and password details and ran

service netif restart

And everything was fine
AX200 works fine
So does AX200 Bluetooth

I'm thinking that windows fouls up the hardware but I'm just guessing
On Ubuntu 22 live everything works perfectly
Soon I'll install. Just testing the laptop for any hardware problems

My other laptop has ax200 without any windows. I'll see how networkmgr handles that
