Following and the physical/logical split noted by , here is a compact, practical checklist and configuration flow to turn a blank box of hardware into a stable, secure network for .

Begin with a clear inventory and goals: list modem/ISP type and credentials, router/firewall model and firmware, switch type (managed or unmanaged), access points, servers/printers, and rough counts of wired and wireless clients. Record which services are required (Internet, file/print sharing, VoIP, guests, VPN) and any constraints (bandwidth, remote users, compliance).

Plan addressing and roles: pick RFC1918 ranges and map subnets to roles (for example staff, guest, IoT). Reserve low addresses for infrastructure (.1 gateway, .2-.10 static), use DHCP reservations for servers/printers, and document the plan. Decide where NAT and DHCP run (edge router vs. separate DHCP server). Choose managed switches if VLAN separation is needed and plan trunk ports and native VLANs.

Suggested configuration order and hardening: update firmware, set strong admin credentials, disable WAN-side management, enable secure management (SSH or HTTPS) bound to a management VLAN or trusted host list. Configure WAN (ISP) and confirm public/WAN IP. Configure DHCP scopes, default gateway and DNS. Implement VLANs and firewall rules that deny by default and permit only required traffic between zones. Create separate SSIDs for staff and guests with WPA2/WPA3 and captive portal for guests if required.

Quick tests and troubleshooting: check link lights and port LEDs, confirm WAN IP and gateway, ping the gateway then an external IP (for routing), perform DNS lookup, inspect DHCP leases, and review firewall logs for blocked flows. Keep a backup of final configs, label cables, and document the address/VLAN map and admin passwords in a secure location.

You will need to tell us what equipment you have already, and what you want to do. For example, how many computers do you have? Do you want it, or them, to connect to the Internet or just to each other? Or, both? :-)

There are mainly two high level components we can discuss...the physical and logical network.

You first need to have some information about what you need this network to do.
