Wi‑Fi walk test
Quick answer: a walk test tells you whether you have a coverage problem (weak signal) or a stability problem (weak hop/interference). Do this before you buy more nodes.
What you need
- A phone or laptop
- Your normal apps (Zoom/YouTube/speed test)
- 10 minutes
Step-by-step
- Baseline: stand near the main router/node. Note speed plus whether it feels stable (no stalls).
- Walk: go to the first problem area. Note whether speed collapses, or if it’s mainly dropouts.
- Repeat: office, bedrooms, living room, garage/outdoor area.
- Count walls: if the worst area is behind multiple dense walls, assume wiring/backhaul is the real fix.
How to interpret results
- Good near router, bad far away: coverage problem (placement, not enough nodes).
- Okay speed, but random drops: interference or weak backhaul/hops.
- Bad through 1–2 walls: dense-wall problem → plan on wired backhaul (Ethernet/MoCA).
What to do next
If it’s a coverage problem
Fix placement first, then use mesh sizing as needed.
If it’s a stability problem
If nodes feel flaky, wired backhaul is usually the win.

Tip
If you have coax jacks, MoCA is often the cheapest way to make a flaky mesh stable.
