What do the LED lights on my Nighthawk router mean?

The Power LED indicates the router status: solid amber means starting, blinking amber means firmware is upgrading, and solid white means the router is ready. The Internet LED shows connection status—solid white indicates a ready connection, and blinking white means traffic is being sent or received. The WiFi LEDs work similarly for the 2.4 GHz and 5 GHz radios, showing solid white when operating and blinking white during data transfer. (Page 11-13)
