Realtek RTL8723DE 802.11b/g/n PCIe Adapter only runs at 2.4 Ghz. How do I get 5.0 Ghz?

[Uvalde78801]

I have the Realtek RTL8723DE 802.11b/g/n PCIe Adapter.   Does this adapter only work at 2.4 Ghz?   I would like to run my laptop at 5 Ghz on my home network.  Any ideas?

It has  Realtek RTL8723DE 802.11b/g/n (1x1) and Bluetooth® 4.2 combo adapter which supports 2.4GHz networks ONLY.

Very interesting, this machine is not old, I don't know why HP gave it that option. It only has one antenna, you can use the following adapters for the series:

Integrated Wireless options with single antenna (M.2/PCIe):

• Intel Dual Band Wireless-AC 9461 802.11 AC 1×1 WiFi + BT5 Combo Adapter (non-vPro) (MU-MIMO supported) part # L25889-005
• Realtek RTL8821CE 802.11 ac 1×1 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) part # L17365-005.
• Realtek RTL8723DE 802.11 bgn 1×1 WiFi + Bluetooth 4.2 Combo Adapter      (your machine, no good)
