WiFi Extenders

It expands the coverage of your existing Wi-Fi network by rebroadcasting your router’s signal to areas with weak or no connectivity.

It needs to be within reach of your router's existing signal. As a rule of thumb, if your phone still shows 2-3 signal bars at that spot, the extender will work well there. Placing it in a dead zone with no signal at all gives it nothing usable to rebroadcast.

Yes, for most homes with weak spots or dead zones — a well-placed extender noticeably improves coverage and cuts down on dropped connections. They won't fix a slow Internet connection at the source, but they're a low-cost way to reach rooms your router's signal doesn't cover well.

No, extenders don’t increase your Internet speed. They improve signal strength and reliability, which can make connections feel faster in previously weak areas.

Most modern extenders are compatible with standard Wi-Fi routers, but it’s always best to check for compatibility with your specific router model.

They're usually two names for the same type of device — both a WiFi booster and a WiFi extender (or repeater) take your router's existing signal and rebroadcast it further, creating a second network you have to switch to as you move around. If a product is marketed as a mesh system instead, that's a genuinely different technology: it creates one seamless network across multiple points, so you don't get dropped connections or have to manually reconnect as you move between rooms — usually the better choice if your budget allows it.
