Draft my home network
Enter your space and device counts to draft ports, Wi-Fi, addressing and security.

Design the whole network
in a practical order.
Plan the Internet handoff, router / firewall, switch, wireless AP, NAS and IoT as one system: topology, addressing, Wi-Fi and security.
START BY GOALFirst plan · About 5 minutes Measure · improve Wi-Fi NAS · cameras Addresses · segmentation Internet problem Power · outage readiness
Start with what you need now
You do not have to read the whole path. Pick the tool and guide that match your goal.
Check room-by-room wireless quality
Record the baseline, then work through AP placement, backhaul and channel improvements.
Estimate storage and transfer time
Calculate camera retention and the time and bottleneck of each NAS backup path.
Plan VLANs and IP addresses
Validate subnets, DHCP, reservations and policies, then map the physical topology.
Narrow down the cause
Diagnose power, link, IP, DNS and Internet access in a safe order.
Start interactive checks →Check PoE and UPS headroom
Add maximum device loads and port counts, then estimate runtime during an outage.

A reliable baseline
Even when one consumer router performs several jobs, separating those jobs makes upgrades and troubleshooting easier.

Core rule The router controls the boundary and addresses, the switch distributes wired links, and APs provide Wi-Fi.
BUILD IN ORDER
Home network build path
01
Topology and device roles
Place the router, switch, wireless AP and NAS before buying hardware.
Plan topology →02IP, DHCP and DNS
Choose the subnet, DHCP pool, reservations and DNS without conflicts.
Plan addressing →03VLAN segmentation
Separate trusted, guest, IoT and management traffic, then allow only what is needed.
Plan segments →04Wi-Fi coverage
Choose 2.4/5/6 GHz, channel widths, AP locations and wired backhaul.
Plan wireless →05Firewall and remote access
Minimize UPnP and port forwarding; prefer an authenticated VPN.
Secure access →06Troubleshooting
Check power, link, IP, gateway, DNS and Internet in that order.
