Question What is this X next to my WiFi Adapter mean?

Does this image mean that the Ethernet is connected? Since ethernet always supersedes wifi in windows, you would not expect the wifi to work when ethernet is already connected.
You can have both "connected" but windows will choose the ethernet over the wifi on most machines because of a field called metric. You can see it in route print command. This is a common way laptops work they will switch to the ethernet as soon as you plug it in and switch back when you unplug it.

In this case it is disconnected.
