Your machine only has a SINGLE antenna. You can replace existing wifi adapter using
- Intel Dual band wireless-AC 3168 802.11AC 1×1 WiFi + Bluetooth 4.2 Combo Adapter (non-vPro) part # 863934-855
- Realtek RTL8821CE 802.11 ac 1×1 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) part # L17365-005
OR you can simply use one of many cheap USB adapters such as

The Bluetooth won't get any reception unless you install the Realtek RTL8821CE 802.11 ac 1×1 Wi-Fi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) part # L17365-005.
The RTL8821CE is designed for the Wi-Fi and Bluetooth to work with only one antenna wire.
The Intel 3168 Wi-Fi card requires two antenna wires in order for the Bluetooth to work, and your notebook only has one.
Below is the link to the service manual where you can find the Wi-Fi card removal and replacement procedure:
