I have just moved house and just reconnected up my MyBookWorld (white light) everything appears fine on the box itself e.g. all the lights are showing as expected etc.
I initially plugged it into my router and subsequently direct into my PC ethernet.
In both cases I am unable to connect via WD Discovery, Windows Networking or via IP address.
I can ping the box without any problems.
I have reset, tried differnet cables etc etc but still no joy.
