DW1820 is based on Broadcom BCM4350 (14e4:43a3) chip. Full details available at wikidevi. I would have expected that card to work OOB because id 14e4:43a3 is listed in AirPortBrcmNIC.kext (PlugIn of IO80211Family kext) but it's maybe subject to SMBIOS whitelisting too.

 

Which SMBIOS profile do you use? Try different ones, starting by Skylake systems. Failing that, try to declare it as compatible with BCM4360 14e4:43a0 through the usual DSDT patch.

 

Edit 8Aug2018: it's the DW1820A that's based on BCM4350, not the DW1820. See below for details. Apologies for the confusion. DW1820 card is NOT supported.

you probably need https://sourceforge.net/p/airportbrcmfixup/code/HEAD/tree/trunk/and lilu.kext I saw  14e4:43a3 in airportbrcmfixup info plist. you might also have to add a fake id for wifi in clover config and use the fix wifi patch with might need also dtgp patch unless you already patched dsdt for those manually. but first test with the 2 mentioned kexts then move onto the clover edits if you need too.

There seems to be some confusion on this card (or I should say these cards), so let's try and clarify the matter. There are actually 2 x cards: a DW1820 and a DW1820A. The difference may be subtle but essential nevertheless...

  1. DW1820 is based on Qualcomm chipset QCA6174A. It carries PCI id 168c:003e. It's unsupported as specified in our inventory list.
  2. DW1820A is based on Broadcom BCM4350 (see wikidevi link above). That card carries PCI id 14e4:43a3. It should be supported OOB.


DW1820:

-> I've updated the wireless inventory accordingly.
