Solution for DW1820A

[lafouffe]

Hello,

For those who the DW1820A card does not work at all. You must add in clover key = "pci-aspm-default" value = "0" type = "NUMBER", according to screenshot.

It worked for me whereas before I tried several cards, I had crash and the wifi had never worked. This works for mac os catalina I have not tried on Mojave.

Have a good day

If you have a DW1820A with the serial CN-096JNT you also have to use the most recent version BrcmPatchRAM3 from here https://github.com/acidanthera/BrcmPatchRAM and the most recent https://github.com/acidanthera/airportbrcmfixup/releases delete the other wifi/bt specific kexts from your efi folder.

The solution is to put ASPM in bios advanced settings (modded bios, 10$ with RSA - no 5 buzz bumps) to be disabled in PCI settings. "pci-aspm-default" doesn't work for all scenarios.

Yep, Is not necessary to set pci-aspm-default to 0. You can disable aspm via Bios>Advanced>South Bridge Configuration>SB PCI Express Config>DMI Link ASPM Control - Change to Disabled.

For Catalina I used those kexts and installed them: BrcmBluetoothInjector.kext BrcmFirmwareRepo.kext BrcmPatchRAM3.kext AirportBrcmFixup.kext

For Mojave: BrcmBluetoothInjector.kext BrcmFirmwareRepo.kext BrcmPatchRAM2.kext FakePCIID.kext FakePCIID_Broadcom_WiFi.kext

Also, before install or update any OS X - needed to remove DW1820A from pci-e port and use lan. My CN-096JNT works fine.

Strange thing, my bluetooth stops working, somehow, after CPU upgrade. But, I found more stable kexts kit for Catalina: https://osxlatitude.com/forums/topic/11540-dw1820a-the-general-troubleshooting-thread/page/10/?tab=comments#comment-92833

this method works for 00jt494 model. There is no other way for me to fix that wifi card.
