Connect the NAS Adapter directly to your computer through the RJ45 network port. Click on "Search Next" see if the NAS Adapter can be detected. If the NAS Adapter IP address and Name appears, go ahead with the firmware recover instructions below. If no information appears, the NAS Adapter cannot be recovered with the instructions below. Consider sending the NAS Adapter in for replacement.
