Hi:

Most likely your notebook only has one wifi antenna cable with the RTL8723BE card installed.

You can upgrade to this dual band AC wifi card with Bluetooth:

Realtek RTL8821CE 802.11 ac 1x1 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.

You can find this model on eBay, or Ali Express.  I see an Intel card listed as the first one on the eBay listing, so don't buy that one.

RTL8821CE - Buy RTL8821CE with free shipping on AliExpress

On the Ali Express listings, make sure the card has the HP Part # of 915620-001

The card will have the same 72 MBPS throughput as the original wifi card on the 2.4 GHz wifi band, but on the 5.0 GHz wifi band, it will have a max throughput of 433 MBPS when you have an AC router with an excellent wifi signal strength.
