Netgear Nighthawk AC2300 orange light when connected to Netgear Powerline 1200 how to fix?

This is my understanding as to WHY it is orange. "If the device you connected is only capable of 10/100 Mbps Fast Ethernet LAN connection, the LAN port lights amber to show that it is connected at a slower speed than what is supported by the router. If your device has a Gigabit Ethernet port, the LAN port lights white."

The Powerline 1200 should be well above 10/100. It is listed as, "10/100/1000Mbps Gigabit Ethernet port" Hence the question, why is the Nighhawk port orange? All other LAN port lights are white as expected.
