HP Laptop unable to find 5Ghz wireless network

HP Laptop 14
Microsoft Windows 10 (32-bit)

New laptop doesn't see 5Ghz wi-fi network. Sees 2.4Ghz fine. Used the instructions on the following webpage, and confirmed that I do, in fact, have a network adaptor that supports both 5Ghz and 2.4Ghz (https://thegeekpage.com/5ghz-wifi-not-showing-up-in-windows-10-solved/). One thing I was unable to do, however, is choose a "preferred band" - that was not available on the advanced properties tab. The router is broadcasting 5GHz signal because a multitude of other devices can see it. The router supports up to 32 devices on the 5Ghz channel, and only 14 are connected. Totally baffled.

Hi:

 

The Realtek RTL8723DE 802.11b/g/n PCIe Adapter is a single band (2.4 GHz) wifi adapter.

 

Any time you see a wireless N adapter with a suffix that ends in b/g/n, that means it is a 2.4 Ghz wifi adapter only.

 

Dual band wifi N adapters have suffixes that end in a/b/g/n or a/g/n.

 

That card is definitely not a dual band wifi adapter and is functioning normally.

 

You may be able to upgrade the internal card to a dual band AC adapter, but I would need to know the full model number of your notebook in order to confirm that one way or the other.

 

Use this guide to find that information...
