Why Should I Buy a WiFi Extender?

A WiFi extender (also known as a WiFi booster, WiFi repeater, and WiFi amplifier) is an electronic device with two WiFi antennas. One of the two antennas receives a signal from a wireless router, and the other antenna broadcasts it after it has been amplified.

When placed correctly, a WiFi extender can help you extend your WiFi network to cover your entire home.

To know whether you’re better off replacing your WiFi router with a more capable model or purchasing one of the wireless extenders mentioned in this article, we recommend you download and use NetSpot to analyze your wireless network.

NetSpot for wireless site surveys

NetSpot is a professional app for wireless site surveys, Wi-Fi analysis, and troubleshooting. You can download it for free, and it works on both Windows and macOS. Even though NetSpot is praised by professional network administrators, its simple user interface makes it suitable even for regular home users.

How to Choose a WiFi Extender?

Your WiFi range extender should support the same WiFi standards as your WiFi router. At the moment, the latest WiFi standard in use is IEEE 802.11ad, which provides data throughput rates of up to 6 Gbps. If you have an older router, it most likely supports only the IEEE 802.11n WiFi standard, also known as Wireless N.

This earlier standard can provide data throughput rates of up to 300 Mbps, making it considerably slower than the newest standard but still fast enough even for larger households.

You should also decide whether you need a dual-band WiFi extender or not. A dual-band WiFi extender can broadcast either on the 2.4 GHz or the 5 GHz band. A single-band WiFi extender can only broadcast on the 2.4 GHz band.

If you live in a densely populated area, the chances are there are many wireless routers in your vicinity that broadcast on the 2.4 GHz band, causing network congestions, which lead to lag spikes and slowdowns. Switching to the 5 GHz band is an easy way how you can avoid these issues and often even enjoy faster speeds and a more stable signal.
