Apparently I'm explaining myself right. I let my neighbors WiFi. Is it possible for them to let friends who come to there house use my WiFi without me knowing. By tethering,bluetoothing, or hotspoting thru my neighbors phone which has my WiFi in it. Therefore is there any app or way of finding out who is hotspoting on my home internet? Sorry...trying to explain this as good as I can.
So you want to know if someone is connecting to your WiFi signal, if you can tell if they are then sharing that signal with someone else? No not really since your router will only see the original connection. Don't share your connection with people you don't fully trust, it opens you up for security issues and liability if they do anything illegal, it will all be traced to your connection.
