Windows 10: How can i connect my 2.4 ghz android device to the my PC hotspot sourced 5ghz band Ethernet

Hi. I am trying to convert my Hotspot connection from 5GHz to 2.5GHz so that my Android phone could connect to my internet connection. I tried looking it up at my settings but the option to change my wireless band is not there. my source of hotspot is 5ghz band ethernet on my pc.

5Ghz band not available when turning on a hotspot

I am quoting a post from a similar thread on the Intel support forum:

"1. Click on "Edit" in Network properties and select 2.4 GHz band and then enable the Mobile hotspot.

2. Next, click again on "Edit" in Network properties and select 5 GHz band and then try to enable the Mobile hotspot. It worked for me."

That would be on the same page as the screenshot...should be an option near the bottom. This is the thread in question:

Different Wi-Fi adapter but still Intel which means settings etc which be similar

 

Can't create 5 ghz hotspot

My laptop is Dell Inspiron 7566, network adapter is Intel Dual-band Wireless AC 3165, supporting both 2.4 and 5 ghz networks; latest Windows 10 version with all recommended updates, all laptop-side drivers are also up-to-date.

So recently I noticed that internet on my phone when it connected to hotspot on computer became really slow. I figured out that my room is virtually jam-packed by 2.4 ghz networks, but there's the only 5ghz network so I decided if I switch hotspot to 5ghz
it should work much better (formerly I created hotspot with automatic band choose and I think that system created 5ghz hotspot, but then something happened and it switched to 2.4 ghz).

But Windows tells me that "The selected network band isn't available. Select a different band and try again". Any suggestions?

 

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.
