If your current WiFi coverage leaves a lot to be desired, you need a good WiFi extender. With a WiFi extender, you can significantly improve your WiFi signal strength in a matter of minutes and extend your WiFi network almost anywhere you want. A WiFi extender doesn’t replace your existing router, it works together with it, making the original signal stronger.
WiFi extenders work like stereo amplifiers used for driving hi-fi systems. They use electric power from a power supply to increase the strength of the original WiFi signal, transmitting the amplified signal in the air. To accomplish this feat of engineering, WiFi range extenders contain two WiFi antennas: one is used for signal capture and the other one for signal transmission.
A WiFi extender is often referred to as “booster”, “repeater”, or “WiFi extender”, but all these names mean the same thing: a device that captures a WiFi signal, amplifies it, and transmits it.
Most wireless range extenders plug into the standard electrical outlet. They can be then set up with the help of the WPS button or a dedicated smartphone app. WPS is a network security standard that allows WiFi-enabled devices to communicate without entering long passphrases.
With modern WiFi extenders, you get to enjoy the same robust encryption protocols as you get with your main WiFi router, so there’s no need to worry about your privacy. However, you should be prepared for some speed loss. Some of the best WiFi extenders on the market can rebroadcast WiFi signal with only a negligible speed loss, but most single-band extenders lose up to 50 percent of the original bandwidth. To minimize the speed loss, it’s paramount to position the WiFi extender in the optimal spot, preferably with the help of a professional app for wireless site surveys, Wi-Fi analysis, and troubleshooting such as NetSpot.
WiFi range extenders come in all sizes, shapes, and price ranges. A purchase of a WiFi extender only makes sense if a purchase of a new WiFi router isn’t a cheaper way how to achieve the same result.
Always make sure to read online WiFi extender reviews before you click on the Order button. As you may know, networking equipment isn’t exactly known for its reliability. Some products work seemingly flawlessly, whereas virtually identical alternatives from other manufacturers only cause headaches.
If you care at all about your security and privacy, avoid products from unknown manufacturers and companies with a poor reputation. With almost 400,000 new malware samples detected every day, WiFi security isn’t something to be taken lightly. In the day and age of targeted ransomware attacks, it often takes just a single determined attacker to bring down an entire company or ruin someone’s life.
To select the best WiFi range extender, you should check your current WiFi coverage to see where the weak spots are. In theory, you could take your smartphone or laptop and simply base your analysis on the WiFi strength indicator icon, but a professional wireless site surveillance app such as NetSpot will give you much more accurate results.
NetSpot comes with two survey modes: Discover and Survey. The former mode is great if you want to get a quick overview of all WiFi networks in your area, but the latter mode is what you need for a comprehensive WiFi survey.
Even though NetSpot satisfies the needs of professional network administrators, it’s accessible even to casual users. The polished, modern user interface removes all complexity from wireless network surveilling, allowing you to generate detailed signal heatmaps with a few clicks.
It all starts with a map of your local area. You can either upload an existing map or create a new map using NetSpot’s map-building tools. After that, it’s time to walk from room to room until you cover the entire area. NetSpot will then analyze the gathered data and present you with results.

Shortly after you buy and install a new WiFi extender, you should verify whether it performs according to your expectations using NetSpot. You can either do a quick, local WiFi analysis using the Discover mode, but we recommend a complete site survey using the Survey mode. The easy-to-understand heatmap that NetSpot generates will instantly help you see whether your new WiFi extender has eliminated the dreaded weak spot.
