How to Identify Your Wall Material and Set It in Range Up
Knock, pin, magnet, drill. How to identify your wall material, what it costs your Wi-Fi signal in dB, and how far the wrong setting moves the answer you get.
Wall material and Wi-Fi signal belong together: a floor plan can be proportionally perfect and still give a misleading placement recommendation if its global construction setting is wrong. Distance is forgiving; a missed category of wall can change the predicted path by many dB.
Range Up uses one material preset for the whole plan, plus global numeric wall, door and floor loss. It does not have a per-wall material picker. Choose the construction that dominates the router-to-target path, then use dense structures as carefully placed wall tiles rather than claiming the app can model every individual wall.
Identify the construction safely#
Use observation before anything destructive. A hollow, papery knock and a stud finder that finds regularly spaced wood or metal usually suggests drywall over framing. A harder, denser sound, older irregular finish or a wall that resists a pin may suggest plaster, masonry or concrete. A fridge magnet can locate metal studs or lath, but metal lath plaster needs extra caution.
If you have permission and know it is safe, a small test hole in an inconspicuous spot can confirm a wall. Never drill where wiring, plumbing or structure may be present, and do not make a test hole in a rental without approval. You normally do not need this level of certainty: select the closest house-wide preset and run a conservative comparison.
Typical 5 GHz one-way loss gives useful context:
| Construction or obstacle | Typical loss |
|---|---|
| Drywall stud partition | 3–6 dB |
| Interior wall with plumbing/wiring | 5–8 dB |
| Brick or cinder block | 10–16 dB |
| Reinforced concrete | 15–25 dB |
| Ceramic or stone tile | 8–12 dB |
| Metal lath, foil insulation or mirror | 20–30 dB+ |
Read how walls affect Wi-Fi for the obstacle logic, and the brick/concrete home guide when dense construction is the central problem.
Set Range Up’s global values correctly#
Planner Settings offers Wood frame, Brick and Concrete. Those presets fill the global wall/door/floor values as follows:
| Preset | Wall | Door | Floor |
|---|---|---|---|
| Wood frame | 3 dB | 1 dB | 13 dB |
| Brick | 10 dB | 2 dB | 17 dB |
| Concrete | 12 dB | 3 dB | 22 dB |
The adjustable ranges are wall 2–18 dB, door 0–6 dB and floor 8–30 dB. Select the dominant construction, not the worst isolated surface. For example, a wood-frame house with one tiled bathroom normally starts at Wood frame; draw the bathroom’s dense path honestly and treat a surprising result as a reason to compare conservative settings, not as proof that every wall is concrete.
This is why a clean plan matters. Drawing the floor plan and using Range Up end to end explain where to place the path walls and router. Use the heatmap to see whether a more conservative setting changes the decision materially.
Let the result choose the hardware, not the preset#
Run the comparison at a reasonable setting and again at the next denser plausible one. If a candidate works only under the optimistic setting, treat it as marginal. A useful extender needs a router link around -60 to -67 dBm and needs to lift the target meaningfully. The Before/After guide gives the dB interpretation.
If brick, concrete or a metal-lath barrier leaves no tile that can both hear the router and reach the target, an extender is the wrong tool. Move the router, use Ethernet or MoCA backhaul or route around the barrier. More repeaters do not make an impenetrable path healthier.
Try the model with Range Up and use the full Wi-Fi extender placement guide when choosing the actual fix.
Use conservative assumptions around dense structures#
The global preset is a practical compromise, not an architectural survey. If the route crosses one substantial masonry chimney, reinforced column, tiled shower stack, full fish tank or mirrored wardrobe, it is reasonable to model that path as a wall and compare the normal preset with a denser setting. What matters is whether the placement decision survives the uncertainty.
Avoid raising the global wall loss merely because one isolated feature is heavy: that makes every ordinary partition in the plan unrealistically dense. Conversely, do not ignore dense items that sit exactly between router and target. At 5 GHz a 10–20 dB mistake can change whether a candidate has adequate backhaul at all.
The app’s slider values should be treated as sensitivity tools. If a recommendation works at 3 dB wall loss but fails at 8 dB, it is fragile. Move the router or choose a more router-side outlet rather than betting the purchase on the optimistic model.
Frequently asked questions#
What wall material should I set in Range Up?
Choose the global Wood frame, Brick or Concrete preset closest to the construction that dominates the router-to-target path. The app uses global loss values, not a per-wall picker.
How much Wi-Fi signal does a brick wall block?
At 5 GHz, brick or cinder block typically costs about 10–16 dB one way. Reinforced concrete is usually heavier, around 15–25 dB.
Does getting the wall material slightly wrong matter?
It can. A small room-size error might change the result by about a dB; mistaking drywall for masonry can move the predicted path by a whole color band or more.
My home has both stud walls and brick walls. Which do I set?
Start with the dominant construction and draw the dense structures that lie on the useful path. Compare a conservative setting if the placement only works under the optimistic one.
