Visual home Wi‑Fi planning

Plan home Wi‑Fi coverage, find weak spots and test fixes before you buy hardware.

Draw your home, place the router and barriers, then click any weak spot to see the predicted signal, the losses behind it and whether moving the router, changing band or adding a mesh node is likely to help.

New diagnostic workflow

Click the weak room and see why

A heatmap is more useful when it explains itself. Use Probe signal and RouterReach breaks the selected point into distance loss, wall loss, floor loss, wireless-backhaul penalty and your real-measurement calibration.

Find the weakest point

The results now expose the weakest sampled signal on the active floor instead of only showing averages.

Explain the path

See which router or mesh node is strongest at the point and which modelled losses are doing the most damage.

Test the fix

Save Scenario A, move the router or node, then compare coverage, dead-zone risk and average signal before spending.

More useful than a square-footage guess

Home size matters, but walls, floors, frequency and placement often matter more. The planner lets you test the variables that actually change the result.

Draw the important barriers

Add plasterboard, brick, concrete, glass or a high-loss metal/foil barrier. You do not need a perfect architectural drawing.

Compare 2.4, 5 and 6 GHz

Higher bands can offer more capacity, but generally lose more signal through distance and dense materials.

Test mesh placement

Add nodes manually or ask the planner to suggest a position. Wireless backhaul quality is included in the estimate.

Start with the problem you are trying to solve

RouterReach is built around real decisions: moving a router, fixing an upstairs dead zone, deciding whether one more mesh node is useful, or understanding why a brick wall changes the picture.

PLACEMENT

Where should I put my router?

A practical placement checklist before spending money on extenders or mesh.

MESH

How many mesh nodes do I need?

Estimate node count from layout, construction and whether you can use Ethernet backhaul.

BUILDING MATERIALS

Why brick walls hurt Wi‑Fi

See how a moderate loss in dB can turn a comfortable link into a marginal one.

REFERENCE

What the heatmap means

The colours are an estimated received-signal planning model, not a measurement of your home. RouterReach uses a log-distance model and applies additional loss when the direct path crosses walls or floors. It then compares the result with a target threshold for your chosen use profile.

Real Wi‑Fi is affected by router antenna design, client devices, neighbouring networks, reflections, furniture, pipes, moisture, wall thickness and many other factors. That is why the result is deliberately presented as a planning aid rather than a guarantee.

Best use: compare scenarios. If moving a router or adding a wired mesh node produces a large predicted improvement, that is useful planning evidence. For business-critical or difficult buildings, verify with an on-site survey.

Common questions

Is this a real Wi‑Fi heatmap?

It is a predictive heatmap based on the dimensions, barriers and equipment positions you enter. A measured heatmap requires signal readings from the real building.

Why does 2.4 GHz often show more coverage?

Lower-frequency Wi‑Fi generally propagates farther and tends to cope better with barriers. That does not mean it is always faster or less congested.

Should mesh nodes be placed inside the dead zone?

Usually not when the backhaul is wireless. A mesh node needs a healthy connection to the upstream node or router; placing it where the original signal has already collapsed can simply repeat a poor connection.

Does the planner recommend products?

No specific hardware is required. The first objective is to improve placement and estimate whether another node is likely to help.

Does RouterReach model mesh nodes relaying through other mesh nodes?

Yes. For wireless mesh, RouterReach now chooses a connected upstream path from the main router through existing mesh nodes, shows the hop count and applies an additional relay penalty to multi-hop paths. Wired Ethernet backhaul is treated separately and does not receive a wireless relay penalty.
