The square-foot number on the box is not your house

Mesh WiFi kits claim huge coverage. The three-packs on this site claim 5,500 to 8,000 square feet. Those numbers assume open space. Your home has walls, floors and a fridge. Plan by nodes, not by the number on the box.

One listing shows how the number is made. Amazon's single eero 7 listing says 2,000 sq ft is "a 25 foot radius". That is a circle of about 1,960 sq ft with nothing in the way. The biggest square room that fits inside that circle is about 35 feet on a side, or 1,250 sq ft. Add walls and it shrinks again.

Our planning rule: about 1,200 sq ft per node with drywall, less with plaster or brick, and at least one node per floor. It is a rule of thumb, not a lab result.

  Coverage claims assume open air. Estimate your node count from square footage, floors and wall type, and learn where to place each node.

• AX3000 and BE10000 are not the speed you get

  The big number on a mesh box adds up every band. Your device uses one. See what your internet plan can use, and WiFi 6 vs 6E vs 7 in plain words.
