Since that model only has/uses one antenna cable, there is only one dual band AC wifi card with bluetooth that you can upgrade to, and that is this one...


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.


The card has the same throughput as the RTL8723BE/DE on the 2.4 GHz wifi band, but on the 5.0 GHz wifi band with an AC router, it has a maximum throughput of 433 MBPS.


Here is the link to the service manual for your notebook, where you can find the wifi card removal and replacement procedure.
