COUNT THE CONNECTIONS

Will five ports be enough?

Reserve one for the router. Then count the links you actually need.

Your wired connections

Count each cable once. Devices below exclude access points and mesh-node links.

If those cover every link and spare, you may need no switch. Otherwise this plan puts all listed links on one new switch.

YOUR PORT BUDGET

Count first. Buy once.

Your result will include the router uplink and spare capacity.

What this planner does and does not check

This is connection arithmetic, not a network design. It does not assess PoE wattage, VLANs, topology, upstream speed or installation safety. Never connect extra loops to add capacity. The small switches shown do not power PoE access points. Follow the exact equipment documentation.
