My laptop doesn't connect to the 5Ghz WiFI.

[AlainTheKlingon]

Hello.

I'm  experiencing an issue about the WiFi connection of my machine.

My laptop (HP Stream Laptop 14-ds0xxx) connects to the 2.4Ghz frequency and it works well, but it can't connect to the 5Ghz.

Specs:

Descrizione : Realtek RTL8821CE 802.11ac PCIe Adapter

Tipo frequenza radio : 802.11n

Driver : Realtek RTL8821CE 802.11ac PCIe Adapter

Tipi frequenza radio supportati : 802.11n 802.11g 802.11b 802.11ac 802.11n 802.11a.

I already used the HP PC Hardware Diagnostic Windows, but it found nothing bad.

I already verified the Modem/Router configuration, but I found nothing bad (and other devices not have problems).

Ideas to fix this issue?

Thanks for your attention and your time.

Alain.

Hi:

The only suggestion I can offer would be to update the wifi driver to the latest version.

2024.0.10.218

sp108893.exe (hp.com)

Also make sure in the advanced tab for the Realtek wifi adapter in the device manager, that you have it set to operate on both wifi bands.

Thanks. After the update of the driver, I solved.

Great advice.

Thanks.
