@L.V,

You should have absolutely no problem with this setup. This is actually how we recommend adding client devices to the satellite nodes.

In the setup shown, you should be able to use any switch without issue. I would recommend, if you haven't made your purchase already, looking into the difference between unmanaged and managed switches. Managed switches provide a user interface to configure/manage the ports, while unmanaged simply work as a passthrough. Both will work, however I usually recommend getting a managed switch as it makes troubleshooting connections far easier.

  @L.V,

While it may be possible, the fact that the NAS is on a separate Subnet may prevent the connections as our Deco products do not have the option to manage multiple subnets; multiple subnet configurations are most often found in business setups for cross-department communications and are typically reserved for Traditional Routers, or Enterprise Grade Access Points.

I believe that your easiest fix, other than changing the IP settings on the NAS, would be to change the range from the Deco App to include this; however, any other assignments already made may be affected.
