How Wi-Fi works in terms of a postman who never walks
Wi-Fi is just a postman who never leaves his sorting office and simply shouts your post across the room at you.
Your router is essentially a desk-bound civil servant, sitting by the fibre optic cable with a stack of data packets that he simply cannot be bothered to carry to the sofa. Instead, he translates every piece of your email into a frantic, invisible radio wave, hurling these electromagnetic shouts across the living room in the vague direction of your laptop. If the information arrives intact, your phone catches it, nods, and quietly whispers a receipt back to the man at the desk, who is currently busy ignoring a stack of urgent firmware updates.
The system relies entirely on these radio waves travelling through thin air, which is a structural nightmare when you live in a house built by a Victorian miser. Walls act like the sort of nosy neighbour who intercept letters just to hold them up to the light, causing your postman to panic and start sending the same Netflix episode over and over again in a desperate, stuttering loop. This is why you end up standing on the landing at two in the morning, holding your phone above your head like a beacon of shame, just to convince the router to throw the data slightly harder toward the bedroom.
Where the analogy breaks downA postman actually knows what a house looks like, whereas a router has no idea where your wall ends and your kitchen bin begins.
