A Wi-Fi extender (also called a Wi-Fi booster or repeater) is a device that helps improve the coverage of your wireless network.
Here’s how it works:
- Your router sends out a Wi-Fi signal. But walls, floors, and distance can weaken it.
- A Wi-Fi extender picks up that existing signal and rebroadcasts it, creating a stronger connection in areas where your Wi-Fi is weak or doesn’t reach (often called “dead zones”).
Key Points:
- ✅ Extends range – Great for large homes, offices, or spaces with thick walls.
- ✅ Easy setup – Usually plugs into a wall outlet and connects to your existing Wi-Fi network.
- ✅ Not the same as a router – It doesn’t replace your router; it just expands the coverage.
- ⚠️ May reduce speed – Since it repeats signals, some extenders cut bandwidth in half unless they use newer technology (like dual-band or mesh systems).
Alternatives:
- Mesh Wi-Fi systems: Multiple units work together to create seamless coverage without the drawbacks of traditional extenders.
- Powerline adapters: Send internet through your home’s electrical wiring.
