Since your notebook only has one antenna wire connected to the Realtek wifi card in there now, there is only one dual band wifi card you can upgrade to.


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.


The card has the same throughput as the RTL8723DE card 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.


Below is the link to the service manual, where you can find the wifi card removal and replacement procedure...
