Hi:

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

The Realtek RTL8723DE 802.11b/g/n (1x1) wifi adapter it comes with only works on the 2.4 GHz wifi band.

Thanks, that solved the problem.

You're very welcome.

If you are interested in upgrading the internal wifi card to dual band, you can upgrade it to this model only...

Realtek RTL8821CE 802.11 ac 1x1 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.

The only place I have been able to find this model is on eBay.

The card has the same throughput as the RTL8723 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.

On a dual band wireless N router, it would have a maximum throughput of 150 MBPS on the 5.0 GHz wifi band.

Below is the link to the service manual.
