Can my router show a connected device that's not really connected? Lets say I have my daughters phone saved on the list. She is supposed to be at a sleepover across town. I see her phone with a green dot on the xfi app. Is it possible it's a mistake or is she really there connected?
I could be mistaken, but I believe she would have to be connected using your wifi SSID/password to appear in xFi. I sometimes see devices in xFi that are not really connected because they are turned off.
