I had bought D-Link DSL 2750U a week back and was working till this morning but as soon as i came in evening its not working, have tried everything reset device , tried to ping not working even with D-Link Setup when i connect LAN cable and search for router it hangs and it says cant find the router even tried with all LAN ports.Only option left for me is go for RMA now where do i need to send over the device to get replacement I had purchased the router from LetsBuy last month.
