My WIFI has stopped working, i mean there is no WIFI option, so i went to the device manager and the Realtek RTL8821CE 802.11ac PCIe Adapter has a problem. I already tries reinstalling the drivers and it doesent work. I dont know what to do, bought the laptop a few days ago, hope that someone can help me.

Hi:

The only suggestion I can offer would be to:

Download and save this driver.

2024.0.10.103/2024.0.4.108 Aug 22, 2019

This package contains the DCHU driver installation package for the Realtek RTL8188EE, RTL8723BE, RTL8723DE, RTL8821CE, RTL8822BE andRTL8822CE wireless LAN Controller in the supported notebook and desktop models running a supported Windows 10 or Windows 10 Cloud operating system.

Go to the device manager, right click on the problem RTL8821CE 802.11ac wifi adapter.

Select Uninstall.  Check the Uninstall driver box.

Restart the PC and install the updated driver I posted above.

Hi

I think it is important to show / prove that there is a Wi-Fi adapter present, IE not loose, and then if there are any possibilities to connect to a network.

First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

NOW begin checking/testing/proving the Hardware is fit for purpose.
Power on your PC, press ESC (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

HOW DO I USE DIAGNOSTICS?

HP PC Hardware Diagnostics Windows is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The tool runs within the Windows operating system in order to diagnose hardware failures. HP PC Hardware Diagnostics Windows comes pre-installed on new HP computers, but if not on yours, download here:- http://ftp.hp.com/pub/softpaq/sp93001-93500/sp93457.exe

Copy, Paste and Save in Notepad, as LBB.bat (not a .TXT) and double click to run.
Preferably run as an Administrator.
OR copy and use the individual command lines as needed.

Post anything non-personal, but relevant please.

@Echo OFF
getmac
netsh lan show interfaces
netsh wlan show interfaces
netsh wlan show drivers

PAUSE
systeminfo
PowerShell -Command "Get-NetAdapter"
PowerShell -Command "Get-NetAdapter -Name * | Format-Table -View Driver"
PowerShell -Command "GIP -Detailed"
PowerShell -Command "Test-NetConnection"
PAUSE

If it is new and these checks fail then it is another matter.
