I think you would benefit from an "Introduction to Computer Networks" type class
It will teach you what a switch and a router do, the difference between LANs and WANs, what DHCP and DNS do. The different ISO/OSI layers involve, TCP vs UDP.
Then you'll be able to setup a home network without issues, because you'll know the different moving pieces and how they fit together.
