Upgrading Pavilion 15z-cd000 wifi Card

[LadyMai]

I am in the process of upgrading my Pavilion 15z-cd000. I’ve maxed out the memory, put in a new battery and switched the regular keyboard out  for the back lit model. I am also replacing my old dual router for one with wifi6.  I would like to be able to take advantage of the wifi6 speeds with my Pavilion, (product number 1DJ46AV), but I don’t know what wifi6/bluetooth card to purchase.  Any help is appreciated.

The series supports following cards

• Intel Dual Band Wireless-AC 7265 802.11 AC 2×2 WiFi + Bluetooth 4.2 Combo Adapter (non-vPro) part # 901229-855
• Intel Dual Band Wireless-AC 3168 802.11AC 1×1 WiFi + Bluetooth 4.2 Combo Adapter (non-vPro) part # 863934-855
• Realtek RTL8723DE 802.11 bgn 1×1 WiFi + Bluetooth 4.2 Combo Adapter part # 927230-855   (probably your machine uses this card)

You can use the first two.

Regards.

Hi, @LadyMai 

What model wifi adapter does your notebook currently have installed?

None of the cards listed are wifi 6 and if your notebook has the RTL8723DE wifi adapter, there is only one antenna wire connected to it, and the Intel wifi 5 cards listed above require two antenna wires to work properly.

There is only one wifi 5 card you can upgrade to when your notebook only has one antenna wire to connect to, and have both the wifi and bluetooth work...

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

You can find this model on eBay, or Ali Express.  I seen an Intel card listed as the first one on the eBay listing, so don't buy that one.

The card will have the same 72 MBPS throughput as the original wifi card on the 2.4 GHz wifi band, but on the 5.0 GHz wifi band, it will have a max throughput of 433 MBPS when you have an AC router with an excellent wifi signal strength.

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

I'm sorry, I didn't think to include what card is installed in my Laptop right now. My current wifi card is the Realtek RTL8723DE 802.1 11b/g/n PCIe Adapter.  Looks like I've got the one wire setup.  I  had looked at replacement parts on HP's site, but could not determine what I needed. Thanks for your help.  I will now look for a Realtek RTL8821CE 802.11 ac 1x1 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005. Thank you too for the service manual link.  HP doesn't make this model anymore, so I am trying to collect as much info as I can. Again, thank you!

You're very welcome.

Yes, unfortunately with only one antenna wire, that is the only card where the wifi and bluetooth will work with just one antenna wire.

The card is still on back order from HP, so the easiest thing to do would be to get on on eBay.

[LadyMai]

Thank you. I will do that.

[Paul_Tikkanen]

Anytime. 

Glad to have been of assistance. 

Make sure you don't buy the first one on the list, because that one is an Intel 3165AC card, not a RTL8821CE.

[LadyMai]

Found and ordered the right card. Thanks!

[Paul_Tikkanen]

You're very welcome.

Here are the links to the latest wifi and bluetooth drivers for the RTL8821CE card...
