Realtek RTL8821CE 802.11ac PCIe Adapter not working. Low signal or not picking up networks available

2020 HP Pavilion 14” HD Touchscreen Laptop Computer, AMD Ryzen 3-3200U
Microsoft Windows 10 (64-bit)

Last week, I bought two identical HP Pavilion 14" HD, AMD Ryzen 3-3200U. 

One of them is having problems with the wifi adapter. The connection is slow, drops, or it even doesn't connect. It is also not picking up the other 8-9 networks that are around the house, which the other laptops (including the identical one) can see. 

I've updated the driver, uninstall and reinstall, and other suggested tips. Nothing seems to work. I wonder if it's a hardware issue at this stage. I've literally used the laptop twice since we bought it, and we urgently need it for the school year starting in two days. 

Please help!!

With HP support help, I upgraded WiFi adapter And BIOs. None worked. We complete reset the laptop, back to factory setting. Didn’t work either. 

Can I assume then that this is a hardware problem then, and I need a new WiFi card adapter ? 
if so, should I get the same? Realtek RTL8821CE 802.11ac PCIe Adapter

@mafalda73 Welcome to HP Community!


I understand that you are facing issues with wifi card.


In that case, I would suggets you perform the wireless module test and let us know.


1. Power off the PC and make sure that it is completely powered off.

2. Press the power button and the moment you press the power button immediately start tapping F2 key, you should see the system diagnostics screen.

3. Look for the component test, under that all the hardware will be listed, please choose Wireless module and initiate the quick test.

Note: If it fails it will generate a 24 digits alphanumeric failure id, please capture that.
