Over a week ago I asked you guys if you might have any suggestions. Well I sorted it out.
I did these steps in the exact order and the driver has yet to crash in 3 days.
- You need to rename the WiFi from whatever its current ACPI name is to ARPT; in my case PXSX.
- Add AirportBrcmFixup.kext to your EFI
- Clear NVRAM with
sudo nvram -c - Rebuild kext cache with
sudo kextcache -i / - Shutdown your computer.
- Flip the power switch and remove the cord.
- For my board the battery removal doesn't reset all the settings. I need to use the CMOS jumper.
- Plug in the power cord and flip the switch.
- Turn the computer on and go through and adjust all your settings to how they were before you wiped BIOS.
- Profit
On the insanelymac forum some guys said there is no need to add the kext since the chipset is BCM4360. They did suggest wifi renaming though. I found on a hardware forum there could be an IRQ hangup or some other odd glitch, in that case you can clear CMOS. It shouldn't happen, but it can. The wifi (Archer T9E) now shows up in IOREG and system info as an AirPort Extreme by Apple rather than Third Party by Broadcom. I did all of the above to eliminate as much as possible affecting driver crashes.
As for Windows and Linux, clearing CMOS was all I needed. For macOS it kept crashing. So I'm guessing clearing nvram and adding the kext + rename solved it there.
