I do not understand the Home network setup. Can you elaborate ?

Please refer to the illustration below:

This is a typical home network for data. make a note of these key points:

1. The ONT (analogous to modem in DSL network) which is the termination point of service provider  and gateway to home network. 
2. The ONT is connected to a Router, In most homes this is a Wifi Router and that is sufficient for the home network (no use of wired clients). 
3. Many ONTs come with integrated router functionality (single box for simplification), but it rare for such boxes to give top-notch performance as they feature entry level routers for cost optimization.
4. An  router will typically have 4 Ethernet LAN ports. So you can connect upto 4 devices directly to it.
5. In case you have a complete and comprehensive architecture as we suggest, its likely your total LAN ports exceed 4 and you need all LAN cables to terminate in a STAR point to a switch area and connected to a LAN switch. One port of this switch is then plugged into the router to give internet access to all wired devices.
6. In case you have large home, you need one or more additional APs and you could plug them into the router (or switch also ...)
7. It is not necessary to buy an install all active equipment at one go. You could just get a Broadband connection, get a a router + Modem and then add switch and AP if you need it later. But the cabling infrastructure has to be made ready in advance. 

Please note that in case you have a very simple requirement to use Wifi only for Internet (WAN access), Want to use Wireless AP instead of router, not use very high speed data plan,  and not share large amounts of data in your (W)LAN, then you can connect the switch directly to the ONT (not use Wifi/Wired router), connect the AP to the switch. In this case the ONT will create the DHCP based subnet for your home network.
