The Realtek R8723DE wifi adapter is a single band (2.4 GHz only) wifi adapter.


You can replace that adapter with this model for dual band AC + 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,


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.


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