Can't connect to 5G! (Seems like a regular problem)

HP Recommended
Pavillion 15z-cw100
Microsoft Windows 10 (64-bit)

Hi all!


Seems like a common problem for hp laptops to not automatically support 5G - or am I wrong?


Either way, I bought this laptop in December 2019 and am shocked it doesn't support 5G when my wife's older laptop somehow picks up the signal.


This laptop picks up the 2.4GHz signal but drops it literally every few minutes making it near impossible to download files for work, stream videos and do any sort of online gaming. I've called my provider multiple times for them to reset the signal but it's no use.


Here's the info:

Model: HP Pavillion Laptop 15z-cw100

Processor: AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx   2.10 GHz

System Type: 64-bit, x64 based processor


Can this model be upgraded in anyway so it picks up the 5G signal?


If not - that's BS and this laptop becomes a piece of junk.

It is hard to believe that all notebook's today don't come with built in dual band AC wifi/bluetooth adapters, but HP seems to have a couple of models that don't.


If your notebook has the Realtek RTL8723DE wifi adapter, that is a single band wifi adapter that only works on the 2.4 GHz wifi band.


Since that model only uses one antenna cable, there is only one dual band AC wifi card with bluetooth that you can upgrade to, and that is this one...


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 at the HP parts store for $16.50.

The card has the same throughput as the RTL8723DE 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.


Here is the link to the service manual for your notebook, where you can find the wifi card removal and replacement procedure.
