If your router isn’t providing the coverage you need, a WiFi extender may be the solution. A WiFi extender, also called a WiFi booster or repeater, is a device that improves WiFi coverage. It amplifies the range of an existing router to reach areas with weak or no signal. A WiFi extender is a useful tool to eliminate dead zones and improve unreliable coverage.
The best WiFi extenders boost the range of your router and offer a solid, reliable signal. Be sure to choose an extender that can handle your current home internet speed. A quality extender is easy to set up and won’t throttle connection speed. Also consider design and space. Plug-in extenders are discreet and only need a conveniently placed outlet. Desktop models can be more powerful but take up more space. For outdoors, a weatherproof design keeps the extender safe.
For large homes or particularly spotty coverage, consider upgrading to a mesh system. Since they work as one system, mesh networks can provide faster speeds, better coverage, and easier management than separate routers and extenders. The right setup will help bring WiFi to all corners of your home, from the bedroom to the office, or even outdoors to the patio and backyard.
