itlwm VS Wireless-USB-OC-Big-Sur-Adapter

Try use airporttlwm.kext. Here

Intel AC 8260 WiFi+BT - AirportItlwm + IntelBluetoothFirmware

This was just released : https://github.com/OpenIntelWireless/itlwm/releases

Yeah there is. I think it’s itlwm.

What part I got an issue with: have to set SecureBootModel to 'Disabled' since i am using AirportItlwm for monterey

Wifi is a little unreliable a few minutes after boot (waiting for AirportItlwm to be stable release)

We have WiFi with the use of a third party TP Link dongle and chris1111's Wireless USB OpenCore Adapter, fully functional trackpad with gestures with the help of BigSurface. Also have touchscreen & stylus working with SSDT-SURFACE although do not use it*

I got the t3u, had to get https://github.com/chris1111/Wireless-USB-OC-Big-Sur-Adapter to get it to work

I found two solutions. The first is a kext named "BlueToolFixup.kext" (https://github.com/acidanthera/BrcmPatchRAM) to make the UB400 work on higher versions. The second solution is a program that makes wireless USB adapters functional even though no drivers were available from the manufacturer (https://github.com/chris1111/Wireless-USB-OC-Big-Sur-Adapter/releases/tag/V16).

try this

You could get something like a wifi dongle online and then use chris1111 wireless USB drivers.... you have to disable SIP in recovery, set SecureBootModel to disabled and disable gatekeeper when installing the drivers though. But once that is done, you should have working wifi. I too use this and have a really cheap and random wifi USB dongle attached which I use for my Hackintosh and the Windows install on my system

Wireless-USB-OC-Big-Sur-Adapter

I know you can get wifi with a sub compatible with this https://github.com/chris1111/Wireless-USB-OC-Big-Sur-Adapter drivers but also please check https://dortania.github.io/Wireless-Buyers-Guide/types-of-wireless-card/usb.html first.
