On the front panel of the Linksys RE4000W, the light has two (2) functions:
  • Power - The power light is located on the front panel.  It lights up when the range extender is powered ON.  The light flashes slowly every three (3) seconds when the device is reset to factory defaults or during a firmware upgrade.  When the range extender is ready for use, the light is continuously lit.  If there is an error, the light flashes quickly (every second).
