Over time, a device’s Internet Protocol (IP) address can change unless you establish a reserved address within your router. With a reserved IP address, RedEye can maintain a reliable communications link with the device (client).
Before you continue, determine your device’s MAC address. That may be as simple as reading it from a printed label on the outside of the device. In the case of a Pioneer VSX receiver, use the VSX remote to navigate to the it’s setup menu.
