I want to upgrade my internal wifi antenna from single to dual. then upgrade to compat. dual ada

[anlau]

Paul,

when you say a dual band card would work as long as there are 2 antennas connected to it, did you mean i dont have to run the 2nd antenna around the screen? i only have one antenna tied to the single band card that im trying to replace, so i am wondering how to install the 2nd antenna. i am not a hardware guy, so would it work if i simply leave the 2nd antenna by the motherboard? Also, do you mind pointing me to an antenna product link that may work with an hp pavilion amd motherboard / realtek dual band card such as Realtek RTL8822BE 802.11ac 2 × 2 Wi-Fi + Bluetooth 4.2 Combo Adapter please? looks like antenna is generic and does not much specification but i dont know any better.

thank you very much in advance.

Hi:

In order to help you I would need to know the full model number or product number of your notebook.

Use this guide to find that info.

If you are referring to a card like the RTL8822BE 802.11ac, the Intel 7260 in the other post would not even fit inside your notebook.

Realtek makes an AC card that works with a single antenna on some model notebooks...the RTL 8821CE.

No need to do a thing, but swap out the cards.

Paul,

HP Pavilion - 15z Laptop
Product number: 5MU54AV

AMD CPU

i made the mistake of getting a b/g/n card and am now trying to address the issue. i am looking at 2 options - hopefully these are the right cards...

1. dual band, but then i need to get a 2nd antenna and figure out how to install it. i don't want to disassemble the whole laptop...

New HP 915623-001 Realtek RTL8822BE 802.11AC/ABGN BLUETOOTH 4.2 NGFF U98H133.00

2. single band. should be able to use the antenna already in the laptop.

New HP 915621-001 Realtek RTL8821CE 802.11AC BT 4.2 NGFF U98H132.00 L17365-005

thank you so much!

Hi:

From what I can tell, you have a pretty new model with a Ryzen processor.

You want this card for a direct swap...

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

The only place I have been able to find this model is on eBay.

https://www.ebay.com/sch/i.html?_from=R40&_nkw=L17365-005&_sacat=0&_sop=15

The card has the same throughput as the 8723BE on the 2.4 GHz wifi band, but on the 5.0 GHz wifi band with an AC router, it has a maximum throughput of 433 MBPS.

thank you so much Paul. Sounds like i should just stick with a single band card?

You're very welcome.

I wouldn't go through the hassle of adding another antenna cable.

If you don't do a professional job (by the book), then you have to jury-rig the setup and make sure you don't short anything out by having the metal transceiver touching the motherboard anywhere.

I have Spectrum cable internet.  I pay for 200 MBPS download speeds.

Unless you are paying for 500 MB or more the 433 MBPS speed should suffice for you.
