Hi dasher and kgp,
I'm having this exact same issue (discussed in this thread
https://www.tonymacx86.com/threads/...d-off-then-stops-working-cant-turn-on.250191/) with 2 different wifi cards, and they work in Windows so I know the cards are good. It seems to be related to the MacPro6,1 system definition, because if I switch the system definition to iMac14,2 wifi works great. I don't want to stay with iMac14,2 though because my SSDT is written for MacPro6,1 power management and I don't know how to recreate it for iMac14,2.
dasher, did you fix your wifi, and if so, how did you do it?
kgp, did you have to do anything special to get the wifi to work with the MacPro6,1 system definition? I did follow your guide on the first page (amazing guide by the way) to try to add the device information to my SSDT, but when I do that my USB 2.0 ports stop working (and probably other stuff too). I don't think I did it correctly though. When I look at my IORegistry I don't see anything remotely close to what you show for the slot in the DefinitionBlock and PCI Device information. I don't see anything with _SB. I think I just don't know what I'm doing and can't find a simple guide to to guide me through it.
Thank you for any help you can offer.
