The disk drive vanished from your notebook because at least one device in your home network has the incorrect data address. A bigger network overhaul will not be essential should you mend that.

Instead, an address is put to it by the router, which functions as an information traffic cop of the network. But your network is a unique instance for the reason that it uses two network routers which are connected to every other. In order for this set up to operate, both routers must be putting the exact same group of IP addresses. That would clarify why your notebook can not find the My Book apparatus if they do not.

Assess your first modem-router to discover what range of IP addresses it puts to other network devices. Be certain the brand new router also puts IP addresses in that range. Additionally, be sure the brand new router’s own IP address falls within that range, and that its address is not the same as any other device’s address in your network.
