Hi:

According to the parts list for your notebook, it comes with a Realtek RTL8723BE Wi-Fi adapter.

That model Wi-Fi adapter only works on the 2.4 GHz Wi-Fi band.

RTL8723BE - REALTEK

You have two options:

1. Purchase a dual band USB Wi-Fi adapter.

2. Replace the internal Realtek RTL8723BE Wi-Fi adapter with this model:

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.
