Can I Replace Realtek WIFI Adapter with Intel Wifi Adapter?

HP Recommended
Pavilion Laptop 15-CS
Microsoft Windows 10 (64-bit)

After a Windows update in April, I've been having trouble staying connected to the internet.  It is not an issue with ISP as other devices are connected without issue.  Have uninstalled and reinstalled the Realtek RTL8821CE 802.11ac PCle multiple times.  Have been knocked off 20 times or more a day until it was occurring every couple of minutes.  Finally found Realtek drivers on HP site and downloaded Friday.  Afterwhich, I couldn't get online at all except for a few seconds at a time.  Today, following instructions I found in an on-line HP manual, I uninstalled and reinstalled again and so far, am managing to stay connected and if I am disconnected, it is only briefly.  My question is, if my current fix deteriorates, do I have the option of replacing the Realtek adapter with an Intel adapter or something that will not constantly fail?  

 

Thanks in advance for any help.

you can check your wifi card detail in bios or device manager in windows. search in google with your wifi card model. and upgrade with same slot wifi card models.

Hi, @PamCan2 

 

All Intel wifi adapters require two wifi antenna cables for work as designed, and your notebook only come with one.

 

So, if you decide to replace the RTL8821CE with an Intel card, you will need to connect the single antenna cable to the Intel wifi card's main antenna terminal, and you will have wifi, but you will not have Bluetooth, as that requires the second antenna cable.
