Yeah, that's what I thought.
• My current board is the 'Gigabyte Z790 Aorus Elite AX Rev 1.1'
• Its specs page says that its Wifi/Bluetooth Card is, "Intel Wi-Fi 6E AX211, supporting 2.4/5/6GHz freq. & BT 5.3, supporting 11ax 160MHz wireless up to 2.4Gbps data"
• Dortania recommended 'Airportltlwn.kext', for this.
• I looked into it, and the official download page states, 'added support for device family AX211', as of v2.1.0, "Support more Killer devices from the AX211 family" and "Support macOS Ventura, Location Services & Wi-Fi", as of v2.2.0
• So I included "stable_Ventura", 'Airportitlwn.kext' v2.2.0 in my EFI & pList
• Made sure 'SecureBootModel' in my pList was set to 'Default', as instructed
Ran a test-install (still haven't created custom SSDTs and USB-Mapping, hope to find time, tonight), and nada. No Wifi or Bluetooth.
I'm hoping it's an SSDT or USB-map issue, which should be determined within the next day or two. I currently have an old 'Fenvi FV-T919 802.11' adapter that I can plug in, but I don't know if it's even still compatible with Ventura.
Just wanted a second opinion, incase I had misunderstood and do indeed need to purchase a separate PCIe card.
Note: I don't use Handoff, just standard device-bluetooth, internet-wifi and AirDrop (effected?).
