I am guessing that Orbi shows the device as connected over WiFi. (Surely you would remember plugging in a new ethernet cable.)
How many WiFi devices do you have total? If there are "not many", then you could power each one off and see if it disappears from the Orbi list of devices. This takes up to five minutes for the Orbi to decide, "It's really gone."
Another method is to look at the MAC address of anything that was recently brought into the house. (Also tedious.)
By any chance, does this Orbi have Guest WiFi activated with no password?
