Hi folks,
Today I got a mysterious failure as the whole system just hung up while working. The keyboard, trackpad and the power button didn't show any reaction (except the long press on the power button). Rebooting stopped at the Apple boot screen.
I didn't make any changes to the laptop recently. After updating kexts to latest version from the-darkvoid, boot without injecting kexts, I had the same problem on the following normal boot again. The solution was to disable AirportBrcmFixup.kext.
I think my wifi card (BCM94352z) is broken

I booted Ubuntu from USB, installed Broadcom drivers and wanted to connect to my network -> System hung up again. Surprisingly, Bluetooth is still working

Does someone have other ideas apart from buying a new wifi card?
Thank you!
Edit: Decided to open the notebook and just reinsert the wifi card, seems to work again.
Edit2: Had to do the reinsert again
