Alright so I'm setting up a network for a small office for a friend of mine. It's sorta an advertising agency/ animation studio with 8-10 persons.

This is what the owner wants for his network: 1 centralized NAS that can be accessed wired or wireless. He will have 3 workstations and up to 5 laptops accessing the NAS, the workstations will need fast and stable connection, laptops can work on wifi.

This is what he currently have available:
- Internet subscription plan of 40Mbps, fiber optics
- 1 modem/router wifi from the ISP, support wireless n/b/g, positioned about 40 meters from the office in a separate room.
- Each workstations has 1-2 Gbit ports and wifi ac

What he needs is to setup 2 separate networks, one is between the NAS and workstations at gigabit speed without internet access, the other is with internet access but without NAS.

Is it possible to setup a Gbit network without internet access? What is the proper way to set this up and what additional devices do I need? (router, switches,...?)
Thank you for your time guys

 
switch <---> Router
switch <---> NAS
switch <---> Access points / desktops

It should be a managed switched that can do link aggregation / load balancing
The NAS should also be capable of link aggregation.
Setup Vlans for desktop and laptop users, prioritise desktop traffic to the NAS, and block internet and vice versa.
Desktop users wired straight back to the switch.
Laptop uses wired back via access points.
Disable the wifi on the router to reduce workload.

Talk to a network expert !
 
As soon as you say you need 2 networks you complexity goes up massively. Now unless what you mean is the workstation ONLY talk to the NAS and do not need internet and the laptops ONLY talk to the internet and you need no communication between. That would be a simple vlan on a simple managed switch. Or you can use 2 completely different unmanged switches.

If as I suspect you actually want your machines to have access to both networks at least for some traffic. You are going to need a actual router or a firewall. The device you buy in the consumer store to hook the internet that they call "routers" do not have the ability to run multiple networks. There are a bunch of option depending on how much money you want to spend and/or if you have the technical abilities to use some of the free software based solutions that run on consumer routers or on dedicated pc.
