My home DSL router/modem has a very simple network 'map' which is basically just a list of devices wired/wireless.
I have a single ethernet cable to the back of the router, plugged into a small powered hub used to provide wired networking to my home office. So there is the hub, and my Mac plugged into that, and nothing else. But I see two wired devices listed - my Mac, and amazon-kljlkij8kj or similar. I do have an Amazon Fire TV stick but it is on WiFi.
Why is the amazon device listed as wired when it isn't, and why is my hub not listed?
