Hi:

 

What model wifi card do you have in there now?

HP Recommended

I am not so sure my wireless model card so I screenshot it. Maybe it is Realtek RTL8723DE ?

Yep, that's the one.

 

With that card, your notebook only has one antenna cable, so the only dual band wifi card you can upgrade to is this one.

 

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

 

You can buy one new from the HP parts store...$16.50

or on eBay...

The card has the same throughput as the RTL8723DE 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.
