D-link dir-280 status light not on... why?

hi, i have one of these little routers, and after a problem with my internet connection i unplugged the router. The other day, when the problem was solved, i plugged the router again, connected it but the status light do not turn on, and i cant enter the router administration. I modify my LAN settings, with my ip address as 192.168.0.100, my subnet mask as 255.255.255.0, my default gateway as 192.168.0.1 and my dns server to 192.168.0.1.
I plug the lan cable to the output ports in the router (i’ve tried all four) and the internet cable to the input port and nothing.
Maybe the router died…?
