Hi. [14e4:43a3] works OOB on some laptop, but have little problems on other laptop.You'd need to get some more information to go on in order to determine if the Broadcom driver can be modified to work with the DW1820A. Stacktraces, kernel error logs etc.
This is due to AirPortBrcm4360 has change in El Capitan and the following macOS version. It introduce much PCI Configuration space operation. After two years reverse engineering, I found the key reason which cause DW1820A not works on some laptop: it's PCI mmio related.
The laptop which DW1820A not works, boot with bcom.panic.invalid-mmio-read=1 may generate a kernel panic.
Also, the following boot args in AirPortBrcm4360 you may interesting:
Code:
io80211.dbgmeminfo.traceflags=0xFFFFFFFF
io80211.dbgmeminfo.allocsize=0xFFFFFFFF
brcmfirewirelog=0xFFFFFFFF
