Last update: 05 May 2019   Questions around this Broadcom BCM4350 chipset (in particular the Dell DW1820A) have resurfaced again so I digged into the matter since most people reported it did not work. Outside the model fitted to Apple MacBooks (subsystem id 106b:0131, rev. 05), Wikidevi lists a few cards cards for this chipset, including: Dell DW1820A Foxconn T77H649.00 (Lenovo part number 00JT494) Lite-on WCBN808B   All those cards carry PCI id 14e4:43a
