<< Solved >> DW1830: Lost fast 5ghz wifi

[Peripatetic]

Hi guys -- I have had the DW1830 card for about 6 months now and I remember I made some Kext changes in clover to enable faster 5ghz speeds in Sierra. But with high Sierra, I can only access the slower 5ghz speeds -- and max out at Tx rate: 300 Mbps.

With the DW1830 and High Sierra, what kexts to patch do I need and what kexts (BrcmNonPatch2.kext, fake Broadcom, etc) do I need?

Latest method, which shows Bluetooth available but not working, has these placed in /L/E/

BrcmFirmwareRepo.kext
BrcmPatchRAM2.kext
FakePCIID_Broadcom_WiFi.kext

I have no Kexts to patch. What am I doing wrong?

Thanks.

Solved

I believe I've solved this one, and here's what I did, so it may help people in the future.

1. Placed the following kexts in EFI/CLOVER/kexts/Other:

1. FakePCIID.kext
2. FakePCIID_Broadcom_WiFi.kext
3. AirportBrcmFixup.kext (Requires Lilu.kext, FYI)

FakePCIID kexts are available here.
AirportBrcmFixup is available here.

2. Placed the following kexts in /Library/Extensions:

1. BrcmPatchRAM2.kext
2. BrcmNonPatchRAM2.kext
3. BrcmFirmwareRepo.kext

Download them here.

3. In Clover, add the following custom bootflag:

1. brcmfx-country=XX
   1. Change XX to your country code (US, ES) or just add #a, ie: brcmfx-country=#a
      1. This change, which uses the AirportBrcmFixup.kext, resolved the 5ghz issue.

Restart and you should be good.
