Hi:

Below is the link to the product specs for your notebook.

HP Notebook - 14q-cs0017tu Product Specifications | HP® Customer Support

According to the specs, it comes with an 802.11b/g/n (1x1) Wi-Fi® and Bluetooth® 4.2 combo Wi-Fi adapter.

Anytime you see a wifi adapter with a suffix that ends in b/g/n, that means it is a single band only Wi-Fi N adapter that works on the 2.4 GHz wifi band.

Dual band wireless N network adapters have suffixes that end in a/b/g/n or a/g/n.

Your notebook comes with the Realtek RTL8723DE Wi-Fi adapter.

Below is the link to the specs on that model adapter...as you can see it only works on the 2.4 GHz Wi-Fi band.

RTL8723DE - REALTEK

If you want dual band wifi capability you will have to purchase a dual band USB wifi adapter, or replace the RTL8723DE 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.
