Product: HP Notebook - 15s-du1004tx
Operating System: Microsoft Windows 10 (32-bit)
My notebook is described equipped with Realtek 802.11a/b/g/n/ac (1x1) Wi-Fi in HP official website. However, i checked my notebook, it is physically installed with Realtek RTL8723DE 802.11b/g/n PCIe Adapter which is not supportable for dual wifi with frequencyh 2.4GHz and 5GHz. Is this a typo error on HP website or it was a manufacturing defect on my notebook? Pls advise.

Unfortunately, I would say that it is an error on the specs page.
The parts list for your notebook indicates that it comes with the Realtek RTL8723DE Wifi adapter.
You could replace the RTL8723DE with the RTL8821CE and have dual band.
You would want this model wifi card, which you can get on eBay or Ali Express, as it is currently on back order from HP.
Realtek RTL8821CE 802.11 ac 1x1 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.
The card will have the same 72 MBPS throughput as the RTL8723DE on the 2.4 GHz wifi band, but on the 5.0 GHz wifi band, it will have a max throughput of 433 MBPS when you have an AC router with an excellent wifi signal strength.
Below is the link to the service manual, where you can find the wifi card removal and replacement procedure.
