Introduction

The use of WiFi extenders can significantly enhance the coverage and signal strength of your current network. However, the decision to use two WiFi extenders simultaneously can have both advantages and disadvantages. In this article, we explore the pros and cons of using two WiFi extenders at the same time, helping you make an informed decision based on your specific network requirements.

Understanding the Drawbacks

When considering the use of two WiFi extenders, it is crucial to understand the potential drawbacks, especially regarding data rate and signal reliability.

Data Rate Reduced by Half

Using a single WiFi extender already reduces the maximum WiFi throughput by half. When a second extender is added, the reduction becomes even more significant, effectively reducing the throughput to a quarter of the original rate. For instance, if your router provides a max data rate of 100 MB/s, a single extender would lower it to 50 MB/s, and a second extender would further reduce it to 25 MB/s.

Double-Hopping Effects

Double-hopping, where the second extender connects to the first extender, can exacerbate these issues. Each extender in the chain receives and retransmits packets, leading to a cumulative data rate reduction. This means that the second extender would operate at one quarter of the original rate, while the first extender still operates at half.

Interference and Reliability

Double-hopping can also make your network more sensitive to radio interference. If any interference affects the first or second extender, it will cascade and affect the entire WiFi service. This can lead to reduced reliability and stability of your network.

Additionally, the limitations posed by double-hopping mean that both extenders need strong signals from the source. This restricts the additional range each extender can provide, which can be particularly problematic in certain environments where consistent coverage is crucial.

When It’s Advantageous to Use Two Extenders

There are scenarios where using two WiFi extenders simultaneously is not only acceptable but also beneficial. For example, if you need to cover two distinctly different areas, each extender can work independently to enhance coverage in separate regions. Otherwise, the only scenario where using two extenders at the same time typically results in a disadvantage is when they are arranged in a double-hop configuration.

Alternatives to Consider

For situations where you need to extend your WiFi coverage but are concerned about the drawbacks of using two extenders, there are alternative solutions available. One such alternative is using an Access Point (AP) WiFi extender. These devices connect to the router via an Ethernet cable, which can be up to 300 feet long, allowing you to strategically place the AP wherever it provides the most benefit.

With a solid gigabit connection, WiFi extenders that use Ethernet maintain full data rates without the reduction that comes with using two WiFi extenders. You can install as many APs as needed, ensuring consistent and reliable network coverage throughout your home or office.

Conclusion

The decision to use two WiFi extenders at the same time should be carefully weighed based on your specific network requirements and environment. While there are significant disadvantages, there are also scenarios where it can be beneficial. Considering alternative solutions like WiFi extenders that use Ethernet cables can help you achieve your desired network coverage with minimal drawbacks.
