As a non-macOS person, I need to #AskFedi for some advice on macmini network issues. I get frequent (every couple of minutes), short (a few seconds) of network disconnects, both when using WiFi and wired ethernet. The same cable works fine for other hardware, including mac laptop. Where do I go to debug this? What (cmdline) tools are there to inspect statuses and review logs? Where do I learn about those things for #macOS? (I'm away from the machine right now, can get to the GUI next week.)
