I'm using the AX201 chip that came with the motherboard and using the same big white antenna that came in the box as well. Range is great when using Windows, and was a little worse in Mac OS Monterey when it worked.
I'm now running Mac OS 13.3 (recently updated from 13.2). Neither versions of Ventura (13.2 or 13.3) have worked, unfortunately. It's especially weird since I can find other devices to connect to, but NOTHING will actually connect, ie; a keyboard, it should give me the option to type in a 6 digit number, but nothing happens. Turning off bluetooth and turning it back on in Mac OS messes it up even more; it doesn't turn back on.
