A WiFi extender is a device that plugs into an electrical outlet and is designed to boost the range of your existing WiFi network. These devices are configured using either a mobile app or a web-based wizard. Currently, there are numerous WiFi extenders available, each promising to eliminate dead zones and provide a stronger, more reliable connection throughout your home.
Understanding how WiFi extenders work and whether they are the right solution for your connectivity issues is crucial. This article explores the functionality, performance, and alternatives to WiFi extenders, helping you make an informed decision.
How WiFi Extenders Are Tested
To accurately assess the performance of WiFi extenders, professional wireless performance software suites are employed. These tools measure the throughput of the extender directly from a nearby computer. This method offers more precise data compared to web-based services like Speedtest.net or Fast.com, as it minimizes latency by transmitting data directly between the extender and the computer, rather than over the internet. Typically, multiple test runs are conducted, and the average of the measurements is used to determine the final throughput score.

In a lab setting, the extender is placed in a room separated from the test laptop, simulating a typical home environment where the router and extender are in different rooms. The distance between the laptop and the extender is varied to measure the extender’s effectiveness at different ranges, usually from 8 to 55 feet.
Optimizing Placement for Best Performance
When setting up a WiFi extender, it’s essential to find the right balance in placement. Placing the extender too far from the router can lead to signal degradation. Conversely, placing it too close might not effectively extend the signal to the desired areas. Manufacturers generally recommend placing the extender about halfway between the router and the area you wish to cover.
Should You Buy a WiFi Extender?
Consider a WiFi extender if your primary goal is to eliminate a single dead zone in your home, such as a spot where you like to browse the web and check email. For basic needs like these, a WiFi extender in the $50 price range might suffice. While more expensive models offer features like built-in Ethernet and USB ports, the core performance often remains similar.
However, cheaper extenders (below $30) may offer less satisfactory performance. For example, models like the TP-Link RE220 and the Netgear EX6120 may seem appealing due to their low price, but tests have shown them to have poor speed and limited versatility. If you opt for a lower-priced extender, be prepared to either temper your expectations or ensure the retailer has a favorable return policy.

When to Consider a Mesh Network
For more demanding tasks such as streaming 4K video or playing online games that require low latency, a mesh network is a better solution. Mesh networks, which can range in price from $100 to $1,000, provide a more robust solution by using multiple units that work together to deliver fast, reliable WiFi throughout your entire home. Given the price reductions in mesh router technology, you can now find capable models for under $150 from well-known brands like Google and TP-Link.

Conclusion
In conclusion, understanding “What Is A Wifi Extender” involves considering its performance capabilities, optimal placement, and alternatives like mesh networks. While extenders can solve simple dead zone issues, mesh networks provide a more comprehensive and reliable solution for demanding applications. Consider your specific needs and budget to choose the best solution for your home WiFi setup.
