What is Wi-Fi?
Wi-Fi is like invisible sound waves that carry your video games and cartoons from the router to your tablet. Think of the router as a person shouting across a playground.
Why does it get weaker?
When you are standing right next to the router, you hear the shout very clearly. But when you run far away, the voice gets quieter and harder to understand. This happens because sound waves spread out and lose energy.
Wi-Fi signals also spread out in a circle. As they travel through walls, doors, and even air, they bump into things. Each time they hit an object, a little bit of their strength disappears. By the time the signal reaches your device at the back of the house, it is much weaker than when it started.
What can you do?
If the signal gets too weak, your tablet might stop working. You can help by moving closer to the router or getting a signal booster that acts like a megaphone to send the voice louder.
Examples
- The router sends out invisible waves that spread like ripples in a pond until they become too weak to reach your toy car.
- A microwave oven heating up lunch creates static that makes your Wi-Fi signal stutter for a moment.
