Hi, I have also DW1820A part # CN-0VW3T3, but 1028:0023.
I was able to get it to work by clover hack injecting:
...
<key>compatible</key>
<string>pci14e4,4353</string>
...
it works without AirportBrcmFixup and brcmfx-driver=1.
But I want to get to work also Apple Watch unlock. Problem is, that with pci14e4,43a0 system not booting. I tried it also with AirportBrcmFixup and brcmfx-driver=2, but still no luck. With brcmfx-driver=1 system boots but it says, that WIFI HW is not present.
Did you use FixAirport and AddDTGP? I can work without this hack, because my path is <key>PciRoot(0)/Pci(0x1C,0)/Pci(0,0)</key>, but may be without this fixes pci14e4,43a0 not working? I just guessing.
Thank you for any suggestion.
BTW. I also found wifi card BCM943602CS that is newest and have 14e4:43ba, but this also not working for me.
