Administrators Hervé Posted May 2, 2022 Administrators Share Posted May 2, 2022 Remember to reset NVRAM from OC picker when you reboot after pasting that revised config file in the EFI folder. Link to comment Share on other sites More sharing options...

Administrators Hervé Posted May 2, 2022 Administrators Share Posted May 2, 2022 There's an additional parameter some people have had to use in Monterey (12.3.1 I think) for the DW1820A: brcmfx-delay. Meaning you need to inject AirportBrcmFix kext too but I think you do. https://github.com/acidanthera/AirportBrcmFixup/releases In the following post, OP set the delay to 27s, there's a good chance it'll fix your issue too: https://osxlatitude.com/forums/topic/17195-solved-e7270-freeze-trying-to-update-monterey-to-1231-opencore/?do=findComment&comment=114253 There is no firmware you can load on these cards except Bluetooth ones and that won't be of any help re: boot loops/freezes.
