Router problems -_-

Hey.
Everytime I plug in the Ethernet cord to the router. It lights up and doesn't blink. After a couple of seconds, it just goes dark and I'm unable to use the router.

It works from time to time (I always have to unplug and it replug it back constantly) and I tried plugging in the router without the Ethernet plugged in and it looks like it works fine (Lights blinking). I plug in the Ethernet after that and it continues blinking for a few seconds then it darkens.

It's a Linksys router. WRT5462 V1 (Cisco)
