@vit9696

 

I'm using this kext to try and get my card working, but I keep getting the dreaded turn wifi on button.

 

my card id is 14e4,43a0 and it is a Asus pce-ac66, it has worked previously under Sierra.

 

@Pavo and I have been trying all day to get this card to work, but it continues to not work.

 

Attaching a kernel log.

oopss i deleted my reply hahahaha...

 

@lvs1974 i think airportbrmfixup is missing some patches for HighSierra.

if i use, sherlocks's kextstopatch, it works fine. but i have to change the target kext

from: 

com.apple.driver.AirPort.BrcmNIC-MFG

to: 

com.apple.driver.AirPort.BrcmNIC

Hi,

To investigate an issue I need a kernel log from osx running with debug-version of AirportBrcmFixup.kext and boot-arg -brcmfxdbg.

BTW: 14e4,43a0 - is a natively supported wi-fi card, why do you need to use AirportBrcmFixup.kext?

AirPortBrcm4360: 43a0, IOProbeScore = 641

@lvs1974

 

I attached the kernel log in the original post did not have the debug version in... so i'll swap it out and upload a new log, this is for mojave and though it may be natively supported this is a asus pce-ac66 card.

 

It has always needed patches to get wifi to work, the kexts load and i get stuck with an indefinite holo wifi icon and cannot "turn wifi on".

Others had this issue on Sierra as well, the only way to get it working was a whitelist patch, setting country code for 5Ghz and fake id of a airport extreme card, which AirPortBrcmFixUp does fake the card.

Mojave shows in AirPortBrcm4360.kext>info.plist only shows 2 pci14e4,xxxx id's and mine is in AirPortBrcmNIC or AirPortBrcmNIC-MFG kext.

 

Though as I said, it does not work as expected, the moment it scans for wifi macOS disables it with turn wifi on and holo icon with or without the fixup kext, though without fixup shows as unsupported wifi module.

added kernel log with debug kext.

@ellaosx, no, it does not.

More over, AirportBrcmFixup blocks loading of AirPortBrcmNIC-MFG (it is a bad driver,  Bluetooth Handoff doesn't work).

 

@Sherlocks, could you explain what is iovar patch doing, what methods are patched. Usually I don't use binary patches, I am trying to implement them in a different way.

And I need to understand the purpose of patch.

Oh ok. so what about AirportBrcmNIC, does it block too? if it does, then are you saying that we need to use fakeid/dsdt and use one of supported id that is found in AirportBrm4360 (even i dont use handoff)?

@fallen00sniper, according to your last kernel log AirportBrcmFixup is not loaded at all... I don't see any lines containing "BRCMFX".

You can check whether is is loaded in terminal: kextstat | grep -i fixup

The debug kext is in my clover kexts folder, when I get home I’ll run kext stat.

 

@lvs1974

zip attached below and included system information window.

 

this is a clean Mojave install, no upgrade/updates.

@fallen00sniper

are you experiencing the intermittent drop before it goes to the wifi ON button?

 

No, mine goes either directly to that problem or when I click on the finder bar icon to connect to a access point, it starts to scan and then goes to the hollow icon with turn WiFi on.

@lvs1974, question...

AirportBrcmFixup blocks only AirPortBrcmNIC-MFG.

why the need to block it? I mean, AirPortBrcmNIC & AirPortBrcmNIC-MFG has the same supported ID's , but AirPortBrcmNIC has precedence over AirPortBrcmNIC-MFG because it has higher IOProbeScore

Since bluetooth Handoff doesn't work with AirPortBrcmNIC-MFG. It is still experimental version...

Lower IOProbeScore does not always prevent kext loading, I saw system where AirPortBrcmNIC or AirPortBrcmNIC-MFG were loaded randomly.

@ellaosx

 

didn't know it needed that.

the kext has been showing up in kextstat, but not in the kernel log as loaded or properly loaded?

 

any how, thanks and here is the new log and the terminal showing the kext is loaded.

kernel_log.zip

I see now, and everything looks fine, AirportBrcmFixup callbacks were called (wlc_set_countrycode_rev, newVendorString. start in AirPort_BrcmNIC).

May be some patches are missing in AirportBrcmFixup, but in my system this kext works perfectly with 10.13.6 and 10.14.1 (0x43b1).

Some functionality in AirPortBrcmNIC depends on device-id.

 

@Sherlocks, could you describe all required patches for 10.13 and 10.14 in details?

@lvs1974

missing probably are:

frdWst's pci patch

Neo.aka.Darkman patch (not sure if you have it already)

 

sherlocks iovar as you mentioned. But since sherlocks discontinued the project, i gathered all his and the rest of the dev's patches and I verified the hex exists.

 

Sending you the attachment in PM.
