Can I access my data if the internet goes down

Hi all

     I would think this would be a basic function but I can’t find anywhere on the net that answers this question.  



If the connection between your local home network and the Internet drops, you can still access your content on your local network.

If your home local network goes down (your router/ISP box is shut down or dies), the network connection will not work on your home network and you won’t be able to access your content.
