Router LED not lit

[Bassbumm]

Router LED was red. I reset router, did setup again. Router LED will not light. Is extender INOP?

[plemans]

there are 4 led's on this device. 

Power led

router link led

device link led

wps led

Are they all out or only the router link? 

If the power light is on (after giving it time to boot), its potentially just not setup or needing a recovery procedure. 

Here's the support site with manuals, firmware, and install guide. The manual and install guide list the leds and what they mean.
