Hello, and welcome to the forum. When my ethernet cable is unplugged, my eithernet status icon in bottom right system tray changes to a world. When I hover over it with my mouse, it tells me a cable is unplugged.
When I'm experimenting like that, I run NirSoft's FullEventLogView because it makes it easy to see everything in chronological order so you can set everything up for your test, start the NirSoft utility, pull out / put back the cable, refresh the view then see if any events occurred that seem relevant.
- I do find it ridiculously easy to accidentally put the view in reverse chronological order then wonder why I'm not seeing anything new added at the top of the list.
- I often then track down the event in Windows' own Event viewer so I can see other events in the same log.
