Under My Devices it said there were 2 wireless connections and 1 wired connection. There is only 1 phone connected via wifi, and my desktop via cable. I deactivated my phone's wifi, refreshed the dashboard, and sure enough the wireless connections dropped to 1. This means my router thinks there is still 1 device connected via wifi but there are none in my home.
Does this mean a neighbour could be connected to my wifi? Or is there another explanation?
Edit: I ran Angry IP Scanner to see what it picked up and it will pick up my phone and router but shows nothing for the IP address being displayed as connected under My Devices.
