upgrading Realtek RTL8723BE 802.11 bgn Wi-Fi Adapter

[redharel]

I have HP Notebook - 15-ay109nj and 802.11b/g/n (1x1) and Bluetooth® 4.0 combo (Miracast compatible).

I would like to upgrade the adapter to newer version which support higher speeds but I can't figure out which one should I buy.

Hi:

Since your notebook only comes with one Wi-Fi antenna wire, there is only one dual band Wi-Fi card you can upgrade to and that is this one:

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

The card has a maximum throughput of 433 MBPS on the 5.0 GHz Wi-Fi band with an AC router and an excellent signal.

You can find this model on eBay, or Ali Express. 

I see some Intel 3165 cards listed on the eBay listings, so don't buy those.

On the Ali Express listings, make sure the card has the HP Part # of 915620-001.

Below is the link to the service manual, where you can find the Wi-Fi card removal and replacement procedure.

Thanks for the quick reply.

I was looking for one on Aliexpress but again I'm confused as there is p.n & p.s number. the p.n is like you said but not the p.s
