When Connecting iPhone via USB - PC drops Wifi

Where do I locate the control settings effecting Windows 11 Home behavior wrt tether connection to a cell phone ? Or so I think this is what I am looking for. Let me explain in more detail.
This started after one of the Microsoft updates, maybe the win10-to-win11 update?
Under normal conditions, the laptops maintains a reliable connection to the home Wifi and the NAS. The NAS is used as our central repository for data. When we want to move photos from a cell phone to the NAS we tether the iphone, via a USB cable, to the laptop. As soon as or shortly after that the computer's wifi connection drops. I am assuming the Win 11 Home is now trying to access wifi via the iphone?
How do I stop Win 11 Home from trying to roll over to the cell phone as a wifi access point, if that is what is happening?
If something else is happening, please help me understand what is going on.
Thank you in advance ,

The easy way is to disable Personal Hotspot from iPhone's Settings.

Garlin, I appreciate the quick response.
Disabled the 'Personal Hotspot' feature in iPhone's settings and tested. Everything behaved.
Thank you, DEL
