Your ISP is probably netflowing their side of the connection so they can troubleshoot it. They most likely have some sort of management/monitoring software for the CPE/ONT/Modem so it most likely would have a log of recent devices by MAC address. He probably was going to ask if your router was an asus because he saw the new device on the ONT port and thought maybe you had the wrong one plugged in and that was causing your issue
