Tried all that. The cable and port works with other devices. As you said most likely network interface got broken somehow Does that mean I need to buy new box now or there a way to fix it?

I did. No Luck:( Even after assigning IP address on DM100, I reserved same IP on router for DM100 MAC address. But don't see DM100 connected on router.

All,

I recently start facing an issue with my DM100. It worked well for almost more than a year and suddenly couple of days back it is not getting IP address from my router. After connecting DM100 with router when I check my router for connected device, DM100 doesn't appear. Also when I goto DHCP option under expert setup on DM100 it shows all 0's in place of IP address. Any idea what could be wrong?

Appreciate your help.

Regards.
