Generally the LED lights on the My Cloud Ethernet port should light up indicating a connection. Could the My Cloud network port be bad or defective? Possibly.
Removing the hard drive from the My Cloud enclosure is an option. One will need a spare SATA port on their computer or use a USB to SATA adapter/docking station. Note that the My Cloud hard drive is formatted for Linux so one will need to use either Linux or Linux drivers for windows to see the various partitions and their contents.
