Hi:
There is only one model dual band Wi-Fi AC adapter you can install.
Realtek RTL8821CE 802.11 ac 1x1 Wi-Fi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.
The card has a maximum throughput of 433 MBPS on the 5.0 GHz Wi-Fi band with an AC router and an excellent signal.
You can find this model on eBay, or Ali Express.
I see some Intel 3165 cards listed on the eBay listings, so don't buy those.

On the Ali Express listings, make sure the card has the HP Part # of 915620-001.
Below is the link to the service manual where you can find the Wi-Fi card removal and replacement procedure.

You're very welcome.
Yes, that one will be fine.
Before you install the new card, go to the device manager and uninstall both the Wi-Fi adapter and driver and Bluetooth adapter (if your notebook also has Bluetooth) and driver in the device manager.
Shut down the PC, unplug the A/C adapter, remove the battery, and install the new Wi-Fi card.
Below are the links to the latest Wi-Fi and Bluetooth drivers for that model card:
