Hi:

The parts list for your notebook indicates that the Broadcom wifi card your notebook has, is of the Half Mini Card (HMC) format, when you google the part number.

In order to upgrade to a dual band wifi adapter, your notebook must have two antennas connected to the wifi card in there now.

So, the first thing you need to do is to confirm that there are two antennas connected to the card in there now.

I do not recommend that you rely on the illustration in the service manual to perform this check.

On some of the newer model notebooks, HP only includes one antenna on models with single band wifi adapters.

If your notebook has two antennas connected to the Broadcom wifi card, then you can install this model AC wifi adapter.

Intel Dual Band Wireless-AC 7260 802.11 ac 2x2 WiFi + BT 4.0            HP Part #710661-001

The card is readily available on Amazon or eBay.

Do your search by the HP part number, not the model of the wifi card.

this is my wireless card, I guess it is one antenna?

By the way, where to get my HP part number?

Hi:

You won't be able to upgrade the wifi adapter unless you are willing to completely disassemble the notebook including the display panel area, to properly run a second antenna.

The part number is on the wifi card.  You can see it in your screen shot.

I would recommend you just purchase an external USB AC wifi adapter.

Thanks! I would buy a USB AC wifi adapter instead
