Wi-Fi coverage guides

62 plain-English guides on dead zones, extender and mesh placement, awkward floor plans and the rooms that never get signal.

Two floor crossings, not one. Which floor holds the router, and where the second unit really goes.

Most homes this size need the router moved, not a second box. How to tell which one you are.

Two devices, one plan: where the second unit goes, whether to buy mesh, and how to verify it.

How many nodes a large home needs, where the one cable should go, and the costs compared.

Why the signal collapses after the second doorway, and where the extender goes in a 55-foot apartment.

One floor, 60 feet end to end, no vertical shortcut. Where the router, extender and attic AP go.

Offset half-floors, two short flights, no true middle level. The landing is where the unit goes.

The shortest line to the far wing goes outside through two exterior walls. Plan around the elbow instead.

Masonry spends most of your signal budget in two walls. Aim through doorways instead.

The slab is not the path. The stairwell is. Here is where the extender actually goes.

Three floors, one stairwell, two party walls, and the landing outlet that fixes most townhouses.

Knocking out walls removes the cheap obstacles. The expensive ones are still there, just invisible.
