El Capitan BCM94360CD Wifi Network Cannot Be Joined

[Lavender2]

I have a desktop build:
MoBo: Gigabyte Z170XP-SLI
CPU: i7-6700K
GPU: GTX970
I am running 10.11.6

I recently installed a BCM94360CD Card, and it should most definitely be an Apple. Connected to the motherboard with a PCI adapter.
My wifi is turned on, and I can see my wireless network, but upon trying to join the network I am met with the message: "The Wifi Network "network name" could not be joined"

I have done all that one can do in this situation, such as deleting network.plist files from systems configuration and letting the computer regenerate them. I am obviously missing something, however, and I have literally spent weeks researching this topic and trying different things other than re-installing (I have a gig in half a month where this computer will be used, reinstalling is a serious last resort).

Try moving the PCIe card that the BCM94360CD is installed on to a different PCIe slot on your motherboard (I know, it sounds stupid, but I've found that certain cards can be picky about what slot they're installed in).

Thank you for your reply. I moved it to a different slot but I won't be able to find out if that works or not because as of the last week the computer has been hanging at the Apple logo. I was able to put the verbose boot flag and somehow that got me into my system but as of today it's been stuck on this message:

ARPT: 0.943651: data written into the PLL_CNTRL_ADDR3 (Fractional) 0000100e

I have another forum for this issue here: https://www.tonymacx86.com/threads/el-capitan-hangs-at-boot-verbose-mode-starts-no-problem.215463/

I booted into safe mode and it looks like moving the wifi card to a different slot didn't do anything. I can still see my wifi network but I can't connect to it, I receive the same message as before.

So after I went through this process of USB booting into my internal drive, I have discovered that even though my computer is booting normally now (and I don't know why) the wifi card still won't connect to my wifi, even though it sees it. So this is still an issue"
