Multi-story homes are one of the toughest layouts for wifi, since signal has to fight its way through floors as well as walls. Here's a realistic way to plan coverage rather than relying on marketing square-footage numbers.

Why marketing coverage numbers overstate real performance

Advertised coverage figures are typically measured in open, obstacle-free conditions — not through multiple floors, furniture, and typical household walls. For planning purposes, it's safer to assume real-world coverage is meaningfully less than the advertised number, especially vertically between floors.

A practical placement strategy

  • Place the main router on the middle floor if your modem location allows it, so signal only has to travel one floor up or down rather than two
  • Place one satellite on each of the remaining floors, rather than clustering multiple satellites on one level
  • Position each unit as centrally as possible on its floor, avoiding corners and closets

Recommended model and satellite count

For most 3-story homes, a tri-band Orbi system with one router and two satellites (one per additional floor) is a reasonable starting point. Larger footprints per floor, or homes with denser construction materials like concrete or plaster, may benefit from an additional satellite or a quad-band system for extra backhaul headroom.

Budget vs premium recommendation

A tri-band system in the 770 tier comfortably handles most 3-story homes for a moderate household. If you have a large household with heavy simultaneous usage across many devices, or a very large footprint per floor, stepping up to a quad-band system provides more backhaul capacity to keep performance consistent.

Frequently asked questions

Should I put a satellite on every single floor even if signal seems fine on two?

If the two-floor setup is genuinely testing well throughout the third floor, you may not need a dedicated satellite there — test with a real speed test in the far corners before adding hardware.

Does stacking satellites vertically work differently than spreading them horizontally?

Signal still has to pass through floor materials either way, so vertical placement generally benefits from the same central, obstacle-minimizing placement principles as horizontal layouts.
