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

Turn off Location Services, bluetooth if not using... You get the idea
