I am sorry if I post this in the wrong section as I see most M.2 Wifi cards are discussed in the laptop sections.
Here is my build:
- ASRock Fatal1ty Z370 Professional Gaming
- Intel i7-8700k Coffee Lake
- ASUS Radeon RX 580 8GB ROG Strix Gaming
- 32 GB DDR4 2666MHz

This motherboard has the usual M.2 NGFF Intel Wifi/BT so I bought the BCM94350ZAE/DW1820A M.2 card that is identical in size and form factor. I attached an image of the Intel and the DW1802A.

My problems are:
- Wifi is working but I only get 802.11n and not 802.11ac like this card supports.
- Bluetooth seems to work (icon) but I see no devices

I followed this advice https://www.tonymacx86.com/threads/broadcom-wifi-bluetooth-guide.242423/ and have listed my EFI/CLOVER/kexts/Other:

AppleALC.kext
AtherosE2200Ethernet.kext
BrcmFirmwareRepo.kext
BrcmPatchRAM2.kext
CodecCommander.kext
FakePCIID_Broadcom_WiFi.kext

Shiki.kext
SmallTreeIntel82576.kext
USBInjectAll.kext
WhateverGreen.kext
XHCI-200-series-injector.kext

As for WIFI you can see that the card is recognized as 802.11 ac but only works as 802.11n, connected to newest Airport Extreme (ac)

As for bluetooth it seems to be on but I can not see any devices. Maybe this section explains that? "Brikkesett:" is "Chipset" (sorry for the Norwegian)

I have attached my config.plist. Sorry if I am a newbie and don't really understand this DSDT stuff :)
I would be glad to get this working as the wifi/bt card is pretty cheap on Ebay and I would like to use it for further projects with motherboards that have onboard wifi/bt.

- One note is that I have all kexts in EFI/CLOVER/kexts/Others. I have not tried to put anything in /S/L/E as some suggest. But I am afraid the system will crash as I have read on other posts.

But no one seems to respond. Meaning there is no solution? Did you try the Broadcom Mini-PCIe WIFI guide?

Is your WIFI working? My WIFI works but I only get 802.11n and Bluetooth does not see any devices.

Same thing as you. Only 2G WiFi. No 5Ghz or bluetooth. Maybe we need to do the 5Ghz patch like the DW1560 and all the USB stuff to get bluetooth recognized. In my case there is no bluetooth anyway, I have no icon

Do you have a link to the 5GHz patch? Is this really a USB issue when the card is not USB?

well, I'm trying to patch it in the same way as the DW1560 but it doesn't work. Maybe @RehabMan knows something about that. The card is compatible, it works fine natively. The only trouble is bluetooth and 5Ghz
 
btw, I tried swapping antennas and everything works exact the same way, no changes. I know that BT isn't an usb card, but I think we need to have the correct SSDT for the USB in order to make it happen.

For the 5Ghz WiFi, no news. I'm trying to patch it but I can't. 2.4Ghz band works fine natively, that's all I can say

but just looking at your config.plist you posted
you did not do any of the
kernel and kext patches for config.plist for BRCM as per guide

  • download config-bcm....
  • paste patch to config...

Clover Broadcom Patches/Download (View Raw)
config-bcm94352-130.plist.zip


WiFi Injection Methods (select one method, remove before installing a different method)
  1. kext enabler, FakePCIID/RehabMan
    • All supported Broadcom WiFi cards/AirPortBrcm4360.kext
    • README: RehabMan/OS-X-Fake-PCI-ID
    • Download: RehabMan / OS-X-Fake-PCI-ID
    • Install with kext installer to ~/Library/Extension:
      • FakePCIID.kext
      • FakePCIID_Broadcom_WiFi.kext
      • Install latest versions as available
    • Download config-bcm94352-1x0.plist.zip (above)
      • use AirPort.Brcm4360 patches (10.12)
    • Paste patch to config.plist/KernelAndKextPatches/KextsToPatch
      • 10.12+-BCM94352-fvco-darkvoid
      • 10.13/10.12 only
      • 10.11/10.10/10.9 patches - see VII. Previous macOS Support

if you are running high Sierra 10.13
you would need these added to your config plist

note:
regarding PMHeart Patch for country above (helpful for 5Ghz working properly)
to convert ASCII to HEX you can go to terminal but i use this
https://www.rapidtables.com/convert/number/ascii-to-hex.html
just type in your country code and it will show you the HEX value.
eg
NO: 4e 4f
US: 55 53
AU: 41 55

US would be
Replace = <66c70655 53eb348d 55d0>

NO would be
Replace = <66c7064e 4feb348d 55d0>

please see my post #11 using AirportBrcmFixup.kext (Lilu plugin) which can accomplish the same thing with bootargument - and also does other patches

with regards to your bluetooth injection

BrcmFirmwareRepo.kext : has to be copied properly into /L/E - does not work in clover/kext/other
BrcmPatchRAM2.kext: can be via clover or copied properly into /L/E
I would put both into /L/E
and remove them from clover

(also fakePCIID and fakePCIIDbroadcom_WiFi - best to put in S/L/E or /L/E as well)

according to your information: you have brcmfirmwarerepo in clover/kext/other


see
https://github.com/RehabMan/OS-X-BrcmPatchRAM

BrcmFirmwareRepo.kext does not work with Clover kext injection, unless using a device specific firmware injector. BrcmFirmwareData.kext can work with Clover kext injection.
Click to expand...

if using terminal you can use these commands to copy the two kexts to /L/E
replace <file location> with path to your kexts


Code: 
sudo cp -R  /<file location>/BrcmFirmwareRepo.kext  /Library/Extensions
sudo cp -R  /<file location>/BrcmPatchRam2.kext  /Library/Extensions

rebuild the cache with this

sudo touch System/Library/Extensions && sudo kextcache -u
Code: 
sudo touch
/Library/Extensions && sudo kextcache -u /
