Why is DHCP grayed out or cannot be enabled?


The most common cause for this is that the PPPoE is enabled on the NVR. You will need to access the NVR using a web browser. After logging into the NVR using the IP address go to Configuration > Network > Basic (if not present in Basic check Advance) > PPPoE and disable it then press Save or Apply. From the local GUI got to Main Menu > System Configuration > Network > TVP/IP > then select the tab PPPoE, disable it and select Apply.
