No problem reporting files, no clue.

Any Ideas?

No ideas, useless post
Two cards listed; one native, the other not
Why do we have to guess what you have and what you did or did not do?

Sure. I've downgraded AirportBrcmFixup to 1.1.8 and immediately got my Bluetooth back. Good enough?
Same card as initial guy that I've quoted, absolutely same signs he reported. "Was working until recent dates before I've upgraded either Lilu or AirportBrcmFixup" -> downgraded and got it back.

Same as previous reply:

AirportBrcmFixup.kext has nothing to with Bluetooth.

Can anyone else proof that?

It is true, both Asus and ASRock. Not true for Gigabyte
Remove Intel and replace with Broadcom.

ASUS ROG STRIX Z390-I Gaming Motherboard specs/pupin/#73

Only choice for Gigabyte is repurpose storage M.2 to wireless M.2, see

WiFi card is detected but cannot be turned on.

Wi-Fi is present in the list of network options in System Preferences -> Network.
The status is "Off". Clicking "Turn Wi-Fi On" button, the button momentarily goes blue but stays as "Turn Wi-Fi On".

Sometimes after a re-boot, the System Preferences -> Network takes forever to fill in (the status bar WiFi icon indicates it is trying to connect). In such situations, clicking on the Wi-Fi option in the network list continues to display the Ethernet details for a minute or two before WiFi details appear.

Following "WiFi Injection".
1. Remove all Wifi patches and kexts
- I cannot find any patches or kexts to remove (nothing mentions wifi or network)
2. AirportBrcmFixup/acidanthera
- README: acidanthera/AirportBrcmFixup
- tried: Clover Airport Fix + AirportBrcmFixup
- tried: Clover Airport Fix + AddProperties(fake device-id) + AirportBrcmFixup
- for "AddProperties(fake device-id)" I just added a WiFi device in Clover; I do not know of any properties I can add
- add Clover boot option "brcmfx-country=NL"
- Installed AirportBrcmFixup.kext and Lilu.kext to /Library/Extensions; rebuilt kextcache.

AirportBrcmFixup.kext has everything to do with Bluetooth, it makes the BrcmFixup kexts not to detect bluetooth device that is the same chip as the WiFi card for DW1820A/BCM94350ZAE.
No logs are logs for the issue, with AirportBrcmFixup.kext version 1.1.9 BrcmFixup kexts no longer see the device and doesn't produce anything in logs. No firmware is loaded to the chip and it doesn't activate as a device at all. Downgrading to version 1.1.8 bring things back.

I am struggling to install a Broadcom BCM4390 card on Mojave. WiFi is working with very high speed but Bluetooth is not available, despite installing RehabMan kexts in L/E.
Please find attached report files zipped.
Thanks so much for any help

Your experiment/conclusion is not valid. AirportBrcmFixup.kext has nothing to do with Bluetooth.
