Is the Wi-Fi appearing and just not functioning?

Please try going to Library/Preferences/SystemConfiguration/ and delete the following:
com.apple.airport.preferences.plist
NetworkInterfaces.plist
preferences.plist
Ok. just did that and now WiFi doesn't appear in Network Preferences at all. Not sure where to go from there. How can I tell if the pcie is picking up the wifi? Bluetooth in the same card is working, but I think that's because it's via USB.

Try launching Hackintool and look in the PCI tab.

Also, does the Wi-Fi appear in Windows or Linux?

It's not showing anything in the PCI section of SysInfo, and I don't think it appears in Hackintool either (output attached). I feel like I've gone one step back. Should I revert anything?
I did notice that WifI is disabled in my bios, but I think that's just the Intel onboard wifi which I want disabled.

I've tried a new Fenti card as well with the same result, so have kind of ruled out that it's the adapter I was using.

EDIT: I don't have Windows/Linux to test on unfortunately

If it's not showing up in Hackintool, they system is not seeing it.

Try enabling Wi-Fi in BIOS.

I reset BIOS settings and went one by one with the recommendations from the guide. With WiFi enabled, it pulls up the following, which is the onboard wifi, but I'd really like to use the Fenvi card.

I have a single PCI slot on my mobo (x16). Do you know of any issues running x1 cards on it? I can't think of any reason the PCI slot would not work. Are there any of my configs impeding it?

@pastrychef It does look like deleting the Library/Preferences/SystemConfiguration files removed WiFi from my system. Where do we go from here?

It should populate itself after a reboot if the Wi-Fi card is detected. Like how your ethernet was detected and auto populated.

Open System Preferences, navigate to the 'Network' preference pane.

Select the '+' icon/button below the list of Network devices.

This should open a Wizard for you to add in your WiFi device, if macOS is detecting it.

This is sometimes required after deleting any files from the /Library/Preferences/SystemConfiguration folder.

Yeah. That's not the Wi-Fi you want...

It seems MacOS is not detecting it then, as I only see Bluetooth and Ethernet as options.

I'd like to rule out hardware issues... Is it possible my SMBIOS (iMac19,1) is not allowing my PCIe card to be read? Or the version of Big Sur?

Are there any settings that would cause the PCI expansion slot to become disabled? As I mentioned, the bluetooth (via USB but on the same card) is working correctly.
