Windows 10: Wifi Hotspot Won't Use 2.4 GHz Network Band

So I have this string of smart lights that are able to connect to wifi and then be controlled by an Amazon Echo. I go to a university whose wifi network doesn't exactly work with these kinds of devices so long story short, I am using the wifi hotspot on my Windows Surface to connect them. The lights are only able to connect to a 2.4 GHz network band and so I had the Surface's wifi hotspot set to use 2.4 GHz. This worked for a while, but now I have an issue where the hotspot will only use 5.0 GHz. Despite having it set to 2.4 GHz, I get a message that tells me it is using 5.0 GHz (see screenshot below). Any fixes to this?

:)

 

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.
