I want to replace the Realtek RTL8188EE wireless card in the laptop.

[MaritimeMan]

I have an HP Pavilion 15-n228us notebook that I wish to replace the wireless card on.  Do I have to use an identical card, or as can I use any mini pci-e card?

Hi, @MaritimeMan 

The product specs for your model indicate that is has an AMD processor and chipset.

https://support.hp.com/us-en/document/c04077065

An Intel wifi card will not work in a notebook with an AMD processor on that model.

That limits your selection of a better wifi card to one of these...and only if your notebook has two antenna cables attached to the Realtek RTL8188EE wifi card in there now.

Broadcom BCM4352 802.11ac 2x2 Wi-Fi + Bluetooth 4.0 combo    HP Part #  724935-001

Broadcom BCM943228HMB 802.11abgn 2×2 Wi-Fi Adapter, Broadcom Bluetooth 4.0 Adapter  HP part # 730668-001

You can find either card on Amazon or eBay.

Search by the HP part number, not the model of the wifi adapter.

Below is the link to the service manual for your notebook.

The wifi card R & R procedure can be found in chapter 5.
