Windows 10: How to create a Dual Band Wifi Hotspot?

Hi, I'm trying to share my ethernet connection and create a Dual Band hotspot. When I turn the hotspot on, with the Network band set to "Any", I get the error message:


You're sharing your connection over the 5 GHz network band. The network might not appear on devices that can only connect over the 2.4 GHz band.


Hardware:

Win 10 Mobile Hotspot config to 5 Ghz band gets: The selected network band isn't available. Select a different band and try again.

Win 10 1703 w/ all updates on and HP 255 G5 Notebook w/ all updates.

Trying to get a WiFi Mobile Hotspot running. Configured with Network Band to 5 GHz gets error "The selected network band isn't available. Select a different band and try again." Have reviewed property settings and all looks good. Laptop has dual band WiFi
radios.

Further information.

1. Laptop is Ethernet network connected.

2. WiFi controller is: Intel(R) Dual Band Wireless-AC 3165 Driver 7/2/2017 19.51.4.2. WiFi connectiod is Enabled or Not Connected. Diagnostics are clean.

3. If I config Network Band to 2.4 GHz, all works well.

4. The laptop connects to WiFi on the 5 GHz band just fine (in place of Ethernet). This test proves the WiFi radio is working and enabled.

Google search on the error message gets no relevant hits.

Any suggestions would be appreciated. Thanks in advance.

Why can't my Windows 10 create 2.4G WiFi hotspot?

The updates in the question and this comment to the other answer clarifies an important point: it's not that a 2.4GHz hotspot cannot be created, but rather that the hotspot is always created on the same band as the main WiFi network: If the wireless card is connected to a 2.4GHz network, then the hotspot is on the 2.4GHz band. If the wireless card is connected to a 5GHz network, then the hotspot is on the 5GHz band.

This is because the wireless adapter in question (and pretty much all dual-band consumer wireless adapters in general) only has one radio. The radio can work either on 2.4GHz or on 5GHz, but not both at the same time. In fact, it can only work on one specific channel (or one specific combination of channels, in case of "wide channels") in one of the frequency bands at the same time. This is a hardware limitation, and it means that when you use the same adapter for both your upstream Internet connection and your hotspot, then both must be on the same channel, in the same frequency band.

Consumer WiFi adapters can often have several virtual connections active at the same time: for example, your adapter has both an client mode connection that connects to your upstream wireless network, and a master mode connection that serves as the hotspot AP. However, both these virtual connections are running on the single radio, and they must share the same channel.
