  1. Install Kext:
    1. Bluetooth: https://github.com/acidanthera/BrcmPatchRAM
    2. Wifi: https://github.com/acidanthera/AirportBrcmFixup
  2. Don't modify any system kext, remove the "brcmfx-driver=X" boot arg if you have
  3. add a property to the WIFI card (change to your path), remove all other properties.
    XML:
    <key>PciRoot(0x0)/Pci(0x1c,0x3)/Pci(0x0)</key>
    <dict>
    <key>pci-aspm-default</key>
    <integer>0</integer>
    </dict>
  4. See screenshot for clover config, get the path from hackintool.

  5. Perfect!!!!!!!!!!!!!!!!!!!!!!!!!

For Bluetooth:
In System Information -> Bluetooth
Or
ALT + Shift + press the bluetooth icon on the menu

If you can get:
Version: v7 c4689

My method currently is,

  1. Set the bluetooth USB port to USB 2.0 instead of internal
  2. Sleep the laptop, wake the laptop
  3. Software unplug the bluetooth, (I plug it in VMware and unplug it)
  4. then bluetooth is normal

  • This has to be done for every sleep.

I don't know a better fix.
but disconnect, reconnect the bluetooth works for me.
In my Asus rog strix Z370 i-gaming, in addition to your methods I turn off the power then turn of the machine again also make BT work, which disppeared after my update macOS.

Just wanted to post a thank you here. I purchased the DW1820A and after messing with it for a few hours, I was ready to toss it in the bin. I was having system instability and the dreaded system hard lock after 10 minutes. By configuring "pci-aspm-default" to 0 all instability is gone, Bluetooth is stable, wifi is stable, i can sleep and resume without issues. I now no longer have my edimax USB wifi connected and could not be happier.

WIFI and BT all work pertfect!!!But every time the laptop is cold-started, it will get stuck in the Apple Logo. The advanced BIOS must disable WLAN to start, and then enable WLAN to restart can get into the system. . .

Yea, good news. I just sold my DW1560 too, With DW1820a I can get 500Mbps wifi about 100Mbps better than DW1560.

Try uninstalling all Bluetooth/BrcmPatchRam kexts - sometimes these kexts can cause boot hangs and wifi dysfunction. Also try @denisuu's method here (post #104) by adding more entries to Clover-Devices-Properties to ensure forcing of the native Brcm4360 wifi driver.
Removing BrcmPatchRam caused wifi and BT to shut down, and then the laptop ran slowly. I tested the linking method here. Only pci-aspm-default = 0 works fine with wifi and BT ... I wonder why the second time (restart) can prevent BrcmPatchRam from getting stuck
