About a year ago our NVR stopped working. After going through troubleshooting, ZModo support concluded that the ethernet port was dead. Now our replacement is behaving in the exact same manner. The device is connected to our router via the ethernet port. The NVR port's green led blinks while the red remains off, and the router port's red led blinks while the green remains off. The router does not show that the device is connected when I go to its configuration page. I have replaced the patch cable and rebooted both devices several times.
