Apple's Network Diagnostics app

[prefersmac]

High Sierra does not have Network Diagnostics (an application that helped you determine the health of your network). In my case, it showed the status of: Wi-Fi, Wi-Fi Settings, Network Settings, ISP, Internet, and Server by assigning each entry/item a green, yellow, or red light. I liked to use this app even though I did not understand the meaning of every item it was supposed to be checking. As I began looking for another method to check the status of the same items I could not understand why the app would check "Network Settings" (which I believe are software settings that apply only to wired connections) when I was using Wi-Fi and "Wi-Fi Settings" is also one of the items on the list. Can someone explain the difference in what the app was checking when it checked the "Wi-Fi Settings" and the "Network Settings"? Thank you
