# What do the 3 light indicators on the Gateway mean?

There are 3 indicator lights on the front of the Gateway:

* The green indicator light **nearest the center** indicates that you have power to the Gateway. If this light is not on, there is no power to the Gateway.
* The **middle** indicator light will be either green for a strong signal, yellow for an adequate signal and no light for a poor or no signal.
* The light **nearest the outside edge** indicates the system status:
  * A blinking yellow light indicates the Gateway is initializing.
  * A blinking green light indicates the Gateway is in Setup Mode.
  * A solid green light indicates the Gateway is ready and operating normally.

Three solid green lights across means you are good to go with a strong signal.

Green, yellow, green (left to right) means you are good to go with an adequate signal.
