Try the reset again. Push the paper clip in, then apply power. Continue to hold the clip for at least 30 seconds, then release it.
If no luck, please report: Do you get a dial tone? Does the light on your router for the port in question come on? If so, can you ping the device? Access its web page? If the port light does not illuminate, try with a different Ethernet cable, connected to a different (known working) LAN port on your router.
