El Capitan BCM94360CD Wifi Network Cannot Be Joined

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...
