Realtek rtl8821ce 802.11ac pcie adapter not working

@c-j-Reid

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• Did you make any changes on the settings of your PC prior to the issue?
• When was the last time it worked fine?

While you respond to that, let's try these steps: 

Use the following steps to open the Component Tests menu.

1. Hold the power button for at least five seconds to turn off the computer.
2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
3. On the main menu, click Component Tests.
4. The Component Tests menu displays.
5. Wireless Module Test - This test checks that the BIOS detects the wireless module and that it is enabled.

To run the test, click the Wireless Module, and then click Run once.

• The Wireless Module Test takes 30 seconds to complete.

If the test passes, try these steps:

Reinstall the network adapter using HP Recovery Manager (Windows 8, 10)

Reinstall original software or drivers using the HP Recovery Manager. If your PC does not locate the Recovery Manager installed, click the ‘next step’ button below.

1. In Windows, search for and open HP Recovery Manager. If prompted for an administrator password or confirmation, type the password or provide confirmation. If prompted by User Account Control to allow the program to make changes to the computer, click Yes.
2. Under Help, click Reinstall drivers and/or applications and wait for Recovery Manager to generate a list.
3. From the combined list of applications and drivers, with the drivers listed first, select the checkbox next to the drivers you want to reinstall. NOTE: The name of the adapter varies, depending on which one is installed on your PC.
4. When the Installation is completed message displays, click OK.
5. Close all open applications, restart your computer, then try connecting to the Internet again.

If the issue persists, follow next steps.

• From the Start screen, type device manager to open the Search charm, and then select Device Manager from the search results. Double-click Network adapters. Right-click the name of your wireless network adapter, and then select Uninstall.
• Click here: https://support.hp.com/in-en/document/c03535285 to complete the troubleshooting steps.

If the issue persists, follow next steps.

1. Open Start.
2. Search for Device Manager and click the top result to open the experience.
3. Expand the category with the device that you want to roll back.
4. Right-click the device, and select the Properties option.
5. Click the Driver tab.
6. Click the Roll Back Driver button.

Hope this helps! Keep me posted for further assistance.

Hi,

What is the model number of the laptop and what OS is installed?

Some things to try to see if the problem can be narrowed down or resolved:

a. Try resetting the TCP/IP network stack and check if that resolves the problem.

If Win 10 is the OS, in the search box on the taskbar (click Start), type command prompt, right-click the command prompt result and then select Run as administrator and confirm.

In the Command window type the following commands one at a time and press Enter after each command and wait for a response before entering the next command. Yes there is a space between the words and the / character but not between the / character and the next word. If you make a typing error use the backspace key and retype the word or letter etc. Some of the commands may take a little while for a response and do not restart the laptop until all the commands have been entered (even if a response says to do it)

Type ipconfig /release and press Enter key.

Type ipconfig /flushdns and press Enter key.

Type ipconfig /renew and press Enter key.

Type netsh int ip reset and press Enter key.

Type netsh winsock reset and press Enter key.

Close the Command window and restart the laptop in the normal manner and check if the problem is still there.

b. Try using the laptop in safe mode with networking and check if the connection can be achieved. If it does a 3rd party program may be causing the problem. Check what programs are loaded when starting the laptop. In normal mode right click on the Taskbar and select Task manager > Startup to view what programs are being loaded when starting the laptop and check if they are necessary or not. Some may be for correct operation so be careful. Check online what the program is for if you’re not sure. If you think that it may be a problem, right click on a program in Startup and select “disable’ and then restart the laptop and check the WiFi. If still no good right click on the program again in Startup and select enable to restore it again etc

c. Try using the laptop as close as possible to the router to check if the connection can be achieved and that it is stable. If so it may be an antenna problem in the laptop.
