With an N 900 Central router can I access every computer and device on the network using it from the WD2Go application for mobile devices?
With WD 2go, you can only access devices that support WD 2go.
The N900C supports WD 2go only for its own internal HD and connected USB devices.
For My Net N900 Central, WD 2go is being supported only for the internal storage. WD 2go is not supported on USB storage devices connected to its USB ports.
