Can you give some more information on your setup?
- Which MyBookWorld - Blue Rings or White Light?
- What OS are you using?
- Is your router providing DHCP or are you using static addresses?
- If Windows, does the WD Discovery utility work?
- Did you try using the hardware reset on the unit? For blue rings, start with power off and hold the button down after re-applying power until the LED’s are lit. For white light, start with power on and hold the button down until the LED’s go out and the unit reboots. In both cases, the network settings will return to DHCP so your router must be set to provide an address.
