Hi,
     Having upgrade my system now to an Asus Rog Crosshair VIII Dark
Hero motherboard with 802.11ax wifi which matches my 802.11ax wifi
router, an Nvidia RTX 3080 graphics card with 12GB of memory, and AMD
Ryzen 9 5950x 16 core cpu, 64GB of 3600 memory, liquid cooled cpu cooler
and 1000W power supply I have stopped running my system in raid and
stopped running Fedora in a VM.
     Having now directly installed Fedora 36 I have both wifi and
ethernet configured in Networkmanager, with wifi configured to
autoconnect and ethernet isn't, but when I start up Fedora I have no
internet access as the only access Fedora sees is ethernet which has to
be started manually to get internet access, and even after activating
the ethernet interface Fedora still cannot see any wifi nodes to connect
to. There isn't any issue with the wifi adapter as I am using that quite
happily under windows.
     What am I missing in the installation to get wifi available?

You may have Intel  AX200 wifi   The Intel driver is iwlwifi, and has to load

firmware for your model:  Linux* Support for Intel® Wireless Adapters

Is this a home build.  Did you install an antenna?

Thanks George. It is a home build and I have the external antenna supplied with the motherboard installed.
Wifi is now working, after stopping ethernet from auto starting at boot and rebooting for the 2nd time it is now working as I expected.

Dmesg should mention the wifi adapter, driver, and whether the firmware was 

loaded.

Dmesg is indicating that iwlwifi found Intel(R) Wi-Fi 6 AX2000 160Mhz, REV=0x340. I can see a message about Intel(R) Wireless WiFi driver for Linux but no indicatior as to what it's name is, and there is a message about Direct firmware load for iwlwifi-cc-a0-69.ucode failed with error -2. Then there is a message api flags index 2 larger than supported by driver, TLV_FW_FSEQ_VERSION: FSEQ Version: 89.3.35.37, and then a message "loaded firmware version 68.01d30b0c.0 cc-a0-68.ucode op_mode iwlmvm.

Use "iw list" to "List all wireless devices and their capabilities."

Use "sudo lshw -class network" to see details of the network hardware

(you may need "sudo dnf install lshw").  lshw should show the model of 

your card -- particularly now with component shortages, vendors may sell 

a given  model wifi card with substitutions for some components, so it could take

time for linux to get drivers for very new hardware. 

lshw is indicating the driver loaded for the wifi device is indeed iwlwifi and that the firmware was

the second one that was attempted to be loaded.

Glad it is working. The driver may be too new for the current kernel firmware support, so my guess

is that the driver is using an old/md/or simpler driver. Unless you actually want to use missing features

of your adapter, the firmware may be OK. If you discover an issue,

https://wireless.wiki.kernel.org/ has drivers too new to be included in the kernel along with advice on

preparing bug reports.
