can't turn on WiFi on BCM94360CD

So I am currently using an Intel 4-port gigabit Ethernet card. It's been assigned en0-en3 interfaces. And Sierra recognizes it during initial setup.

I bought a BCM94360CD (shows up as en4 on ifconfig)and that's also recognized by OS X but my problem is that I cannot turn it on. Pressing "Turn WiFi on" on Network Settings does nothing.

Also Bluetooth settings is not showing. The adapter has a plug for USB and I have connected that to the back of the motherboard.

Any ideas what I could be doing wrong? Thank you
