Administrators Hervé Posted May 4, 2021 Administrators Share Posted May 4, 2021 Try the card in all PCIe slots: WLAN, min-PCIe and WWAN. It should at leat be reported in IOReg; also make sure all wireless features are enabled in BIOS. Link to comment Share on other sites More sharing options...
mringis Posted May 4, 2021 Author Share Posted May 4, 2021 (edited) I just try the card in all 3 slot and still not working. In system it said no driver installed. I don't know if I miss something in patching or not. Thank you. Edited May 4, 2021 by mringis Typo Link to comment Share on other sites More sharing options...

Administrators Hervé Posted May 4, 2021 Administrators Share Posted May 4, 2021 @mringis Apple dropped AirPortBrcm4331 kext in Catalina; as such no support for Broadcom card 14e4:43b1 without applying some tricks. Look into our published wireless cards 2nd inventory for details. Link to comment Share on other sites More sharing options...
