Realtek RTL8821CE Adapter not showing 5G networks

[pskelly815]

My laptop is not showing 5G networks.  I have a Realtek RTL8821CE 802.11ac PCIe Adapter in my laptop, which according to the Realtek page and other users on this site, should show 5G networks.  However, when I go to CMD and enter 

netsh wlan show drivers

 it shows the following information:

Interface name: Wi-Fi

Driver : Realtek RTL8821CE 802.11ac PCIe Adapter
Vendor : Realtek Semiconductor Corp.
Provider : Realtek Semiconductor Corp.
Date : 12/4/2019
Version : 2024.0.10.209
INF file : oem16.inf
Type : Native Wi-Fi Driver
Radio types supported : 802.11n 802.11g 802.11b

Is there something that I'm missing?  According to other users on this site, it should show the letters for 5G radio types as well.  As it states, I'm on the 2024.0.10.209 driver and trying to get some help.

Thank you.

@pskelly815 Greetings from the HP Community!

Have you run a wireless card test on your computer?

Download and install the HP Hardware diagnostics tool from this link. 

Once installed, shut down your computer.

Wait for a minute. 

Turn the computer On and keep tapping F2 repeatedly on startup to enter system diagnostics. 

Select the component test and run a wireless test on your computer. 

Refer to this HP Article for assistance. 

If the test fails or does not detect the wireless card, it could be faulty.

If it passes the tests, install all available windows and HP updates using a wired network to resolve the issue.

Keep me posted, as I (Or a trusted colleague) shall follow-up on this case to ensure the concern has been addressed, 

And your device is up and running again, only in case you don't get back to us, first! 

That said, If the information I've provided was helpful, give us some reinforcement by clicking the solution and kudos buttons, 

That'll help us, and others see that we've got the answers!

Good Luck.

Hello, I ended up downloading the newest driver for the adapter off the HP website based on some other threads that I read.  I uninstalled the current driver and installed the newest one, which seems to have solved the issue.

I'll keep your solution in mind in case I still have issues in the future.  I'm very hesitant to rely on something that requires a wired connection though as this laptop doesn't have an ethernet port and I don't really want to buy a USB to ethernet cable just for this.

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?
• Have you made any hardware/software changes?
• Did you make any changes to 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:

4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer. If the issue persists, follow the next steps.

Most notebook computers have a button or keyboard key to turn the wireless signal on and off. Check the button or key status to confirm if the wireless signal is on.

1. Press the button once, wait 10 seconds, and then observe any changes to the wireless connection icon in the notification area and to the LED light on the wireless button or key.
   • If the button or key does not have a light, hover your mouse over the wireless connection icon in the notification area of the taskbar to see the current connection status.
   • If the wireless signal is turned on, try connecting to the Internet again.
   • If the wireless signal is turned off, press the button or key again to turn it back on, and then try connecting to the Internet again.
