Dave, I have wondered sometimes if my Win10 desktop has stayed with the ethernet connection or has skipped over to WiFi; it can do both and the router is pretty close, but checking now it appears to be on the cable connection.

I try when possible to use ethernet connections for speed and reliability; I have an extender in my den on the farthest point of the house that is connected via cable to increase WiFi and because sometimes my next door neighbor needs to connect to my WiFi to work. Her router is on the farthest point of her house from the kitchen table where she works on the laptop, so my extender is closer for her. (Good neighbors share WiFi passwords. She also shares power from her generator when the lights go out. Win/win!)
