I just bought a used Dlink 615 its the E3 model. I bought it cuz it supports dd-wrt. But I got issues I plug it in the power outlet. All light turn on then they go out leaving the power light on/orange. I plug the Ethernet from PC to router no light comes on plug on my ISP modem in the internet port no light. Why are no lights coming on . pressed the reset button I also tryed holding it down for 30secs nothing happens.
