What is a Wi-Fi extender and how does it work?
A Wi-Fi extender, also known as a range extender, is a device that amplifies and relays the Wi-Fi signal from your router to areas where the signal is weak or nonexistent. Essentially, it works by receiving the existing Wi-Fi signal from your router and then rebroadcasting it, which helps to extend the coverage area.
When setting up a Wi-Fi extender, you typically place it within the range of your router’s signal. It connects to your network, and then you can move further away from the router while still maintaining a stable connection. The extender creates a new network name or uses the existing one, making it easier for devices to connect.
Do Wi-Fi extenders actually improve signal strength?
Yes, Wi-Fi extenders can significantly enhance your signal strength in areas of your home or office that experience weak connectivity. They help eliminate dead zones by capturing and amplifying the original signal, thereby enabling devices in hard-to-reach areas to connect more reliably to the internet.
However, the effectiveness of a Wi-Fi extender often relies on proper placement and quality of the device. If an extender is placed too far from your router, it may not receive a strong enough signal to relay, leading to subpar performance.
