This light indicates that the modem is sending a Wi-Fi signal. If the light is on the green, you should be able to see and connect to the Wi-Fi network.
If you are connected to the Wi-Fi hotspot, it will flash green to indicate data going to and from the router. If the router is connected to another Wi-Fi hotspot (Wi-Fi relay), it will also flash because it has the data flow.
