What do the LEDs on the back of the device indicate?

Ethernet LEDs on the back of your unit indicate connection speeds. Each Ethernet port on the back panel of your device has 2 LEDs to indicate its status when an Ethernet device is connected. 

Ethernet LED is Green: Ethernet device is connected to the cable modem at 1000 speeds (Gigabit Ethernet).

Ethernet LED is Orange: Ethernet device is connected to the cable modem at 10/100 Mbps speeds. 

The LEDs blink (in orange or green) when data is being passed between the Ubee device and the connected device.
