Is Realtek RTL8822CE 802.11ac PCIe Adapter support 5GHZ band?!

[Ali3131]

I just bought a dualband router, but my laptop doesn't detect the 5GHZ band, while my other laptop and cellphone detects it. Does the fq0022au laptop not support the 5GHZ band??

Hi:

Yes, the Realtek RTL8822CE is a dual band Wi-Fi adapter.

Update the Wi-Fi and Bluetooth drivers and see if that helps any.

Wi-Fi:

2024.0.10.227

thanks for responding, unfortunately my problem is not solved yet.

You're very welcome.

Sorry that the driver update didn't work for you.

Make sure your router is set to allow mixed types of 5.0 GHz wifi adapters to connect (A, N, AC, AX)

If it is, and you haven't messed with any of the Wi-Fi card's advanced settings in the device manager trying to fix the problem, then the card is probably defective.  If you did change any of the advanced settings, change them back to their default values.

You may want to consider replacing the RTL8822CE with this model Wi-Fi adapter which will also work in your notebook, according to chapter 3 of the service manual.

Intel Wi-Fi 6 AX200 ax 2×2 + Bluetooth 5.0 MU-MIMO M.2 2230 non-vPro   HP part # L35282-005.

Below is the link to the service manual where you can find the Wi-Fi card removal and replacement procedure.

This fixed my network problems. My wifi was continuously giving the ERR_NETWORK_CHANGED and would cut in and out every few seconds. I had to use my hotspot to download the file because the wifi wouldnt stay connected for longer than 5 seconds.

are you using win11 and FQ0022AU too?

I have an HP AIO 32-a0012na, which is also fitted with a Realtek RTL8822CE 802.11ac PCIe Adapter. Despite being within 10m of my WiFi router it will frequently disconnect from the 5Ghz band and default to 2.4Ghz. It's quite obvious when this happens as games begin to stutter and websites take longer to load.
Within Device Manager the preferred band is set to '5G First' but, this has had no effect in bumping the card across to the 5Ghz band.

So today I thought I'd experiment with the Wireless Mode settings. Using the latest drivers, the card offers me a choice of the following modes: 802.11a, 802.11b, 802.11g, 802.11b/g, 802.11a/g or 802.11a/b/g. There is no option to choose 802.11n or 802.11ac, despite being listed as an 802.11ac adapter?!

As far as regards Frequency bands, Modes 802.11g and 802.11b use 2.4Ghz at 54Mbps and 11Mbps respectively. Mode 802.11a uses the 5Ghz band (at 54Mbps). So I decided to set the Wireless Mode property for the Adapter to 802.11a (instead of 802.11a/b/g). The result of which is that the card defaults to the 5Ghz band and my connection speeds have been restored! Maybe try selecting a specific mode to see if that helps you out?

It's worth noting that the 5GHz band is less congested and provides faster data rates than 2.4GHz, but it also has less range than 2.4GHz. The 2.4 GHz band is around 75 to 100ft; the 5 GHz band is around 25 to 35ft (at full speed).
