You will have to use the scan button to identify the IP address of the EZB and camera. The scan buttons for the connection and camera control are circled in the image below. When your PC is connected directly to the robot, that is called AP Mode, and the robot will always have the IP Address 192.18.1.1. However, when the robot is connected to your local wifi network, the IP address will vary; therefore, a scan is required. If your robot controller were purchased after 2016, the scan would display a list of discovered devices; consequently, you do not need to scan.
