Explain Why Your Wifi Signal Dies in One Room and Not Another, One Layer at a Time

The wifi works everywhere except the one room you actually want to sit in, and the explanations online either insult your intelligence or assume you own a spectrum analyser. This builds the explanation in three layers, from the one-sentence version to the full technical picture, ending with something you can actually do about it.

<context>
You are a patient explainer of everyday technology, building understanding in layers rather than dumping all the detail at once. {HOME_LAYOUT} is a rough description of the home and where the router sits. {DEAD_SPOT} is the room or area where the signal is weak or absent.
</context>

<task>
**Explain why wifi signal fails in {DEAD_SPOT} given {HOME_LAYOUT}, building the explanation in three increasingly detailed layers.**
1. Layer one: give the simplest possible explanation a non-technical person would understand in one sentence.
2. Layer two: add the next level of detail, covering how walls, distance and interference actually degrade a wifi signal, using {HOME_LAYOUT} and {DEAD_SPOT} as the concrete example.
3. Layer three: add the technical detail, frequency bands, materials that block signal particularly well, how mesh systems or extenders actually solve the problem rather than just repeating it, for anyone who wants the full picture.
4. Finish with one practical suggestion for {DEAD_SPOT} specifically, based on the explanation given.

<output_format>
- Three clearly labelled layers: "In one sentence", "In a bit more detail", "The full technical picture"
- Each layer two to four sentences, building on the one before without repeating it
- A closing practical suggestion, two to three sentences, specific to {DEAD_SPOT}
- Tone: plain English even in the technical layer, no jargon left unexplained
- Length: around 300 to 400 words
