    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 <https://www.intel.ca/content/www/ca/en/support/articles/000005511/wireless.html>

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.

regards,
Steve
