does your router give you the MAC address of the device? You can look it up to see who manufactured it and then narrow down. This could be a device that has a web service running is all you are seeing right now.
Don’t need the router. If you’re on windows or linux, you just ping the ip then enter ‘arp -a <ip>’ it will show the MAC address for the IP from your machine’s arp cache.
