I recently bought a BCM94331CD WiFi/BT card and a PCI-E x1 adapter for it. The adapter only has 3 antennas, while the BCM94331cd has 4 pigtail connectors. I've just connected 3 of them randomly, and left out the other. Bluetooth is working fine, so I've probably connected that antenna correctly, but WiFi is not. At first, it would only pick up a signal 10 feet away as minimum strength, and refused to connect. After changing the port left unplugged, I got more reasonable signal strengths, but...
Do I need 4 antennas for my BCM94331CD?
