Upgrade my wifi adapper to 5GHz

[Belguys]

Hi,

My desktop is currently using Realtek RTL8723be 802.11 bgn Wifi adapter, which only supports 2.4GHz. I wonder how I can get a compatible upgrade for 5GHz wireless.

I checked on HP part list: http://partsurfer.hp.com/Search.aspx?searchText=P5Q80AV. However, I did not find anything particular. It mentioned "Wireless LAN - 11ac INT 3165 M.2 MOW", but I'm not sure if it refers to this one:

Could you give me some advices about which device I could use for upgrade?

Thanks a lot

Hi:

How many antenna cables are connected to the realtek card in there now?

[Belguys]

Zero.

I don't have any antenna or wire cables connected outside. The card in the box works directly with Wifi.

I just saw a similar post which solved by the same device I found: https://h30434.www3.hp.com/t5/Notebook-Wireless-and-Networking/upgrade-wifi-to-support-5GHZ/m-p/6491...

Instead of desktop, this question is about a notebook. And I did not find such supported advice list in my user guide.

Can anyone help me confirm I can go with this Intel AC3165?

Sorry, I think I missunderstood your question.

I opened my box, and saw two cables connected to my network card.

Hi:

Yes, I see the two antenna wires going to the Realtek wifi card.

Yes, you can replace it with the Intel 3165.

But, I would go with the 7265, or 8260 2 x 2 AC adapters.  Those have twice the throughput as the 3165.
