Network Diagnostics app missing

The Network Diagnostics app is missing from High Sierra. I used it regularly to diagnose network probems, as it showed the status of:

Wi-Fi
Wi-FI Settings
Network Settings
ISP
Internet
Server

It was particularly useful to identify when you had an ISP connection but no Internet connection.

I tried restoring the old app from Sierra, but it did not work.

Does anyone know of another app that can be used to see the network status and diagnose problems with the network connection: i.e. is it my Mac, my router, or does the router not have an internet connection?

MacBook Pro with Retina display, OS X El Capitan (10.11)

Replying to myself. Those google search things about using terminal command do not work.

Hold down option key and click WiFi symbol in menu bar and select "Open Wireless Diagnosics..."

How does this help one know where the problem is? How does changing one's internal wifi connection tell you that the problem is with the ISP connection to the internet?

I am interested in solutions, not in the nature of technical problem. My solution works a 100%.

Thanks Keith. I can’t get the right files somehow from my computer still using Sierra. I have some background learning to do to understand where I am screwing up I think

This is all greek to me. So much for user friendly. Very disgruntled by this BS.
