How many times have you had to change rooms because the Wi-Fi signal is weak? I imagine quite a few, like most of us. As the Wi-Fi signal weakens as someone moves away from the router, the solution to the problem is one: Wi-Fi Extender.

So together we will discover what are the main features you should consider when buying a Wi-Fi Extender, how it works, and exactly what problem it can solve for you.

What does a WiFi Extender do and how does it work?

First of all, let's start with the basics of this device. A WiFi Extender, also known as a WiFi booster or WiFi repeater, is a device that boosts the existing wireless signal from a router to extend its coverage area and re-broadcasts the WiFi network it is connected to. In short, extenders connect to your existing network and then create a second one.

You can set up the extender using either your phone or your computer, going through an app or website to connect the router to your WiFi network. For better results, install the Wi-Fi extender between your router and any area that does not have a signal.

Your router's location

Before you buy a WiFi Extender, first examine the location of your router. For example, let's assume you have placed your router in the corner of your basement.

With this location, you probably have poor connection on the main and second floor, especially in the opposite corner. And you may be looking for an extender to solve the bad Wi-Fi signal.

If your router is already in a central location and you still have dead Wi-Fi spots in your home, then consider a Wi-Fi Extender

The Frequency Factor

Most WiFi Extenders operate on one of the two main WiFi frequencies, 2.4GHz and 5GHz. Both frequencies have their advantages and your choices may depend on your specific needs. Let's see how WiFi extenders relate to these frequencies and what capabilities they offer:

2.4GHz WiFi Extenders

• Greater coverage range
• Compatibility with older devices
• Interference issues if multiple devices are used on this frequency

5GHz WiFi Extenders

• Higher speed
• Less interference and more stable connection
• Limited coverage range

2.4 & 5 & 5GHz WiFi Extenders (Tri Band)

• Avoidance of interference
• Higher speeds with the ability to operate two simultaneous 5GHz wireless networks
• Better coverage
• More devices, usually with 2.4GHz still available for connected devices that only support this frequency

Overall, depending on the devices you use and your coverage area, the choice between these frequencies will determine the best WiFi extender for your needs.

WiFi Technology

When searching for a WiFi extender to use with WiFi 5 (802.11ac) or WiFi 6 (802.11ax) technology, you want an extender that can fully utilize the capabilities of these standards. Below you can see a comparison of their differences and advantages.

The above differences highlight the advantages of WiFi 6 technology compared to WiFi 5, offering even higher speeds, greater performance, and improved management of connected devices. However, the choice between the two depends on your needs and usage environment.

Choosing WiFi Mesh

Many WiFi Extenders offer the option of WiFi Mesh. This is an integrated home WiFi system with multiple access points designed to eliminate dead zones and provide seamless WiFi in your home with higher speeds and more devices. It automatically selects the best node for connections, ensuring continuous and reliable connection without interruptions.

Mesh WiFi devices typically have flexible management applications that allow for easy installation, configuration, and monitoring of your network while receiving software updates that improve the performance and security of your network.

Ethernet Ports

It is obvious that WiFi Extenders are wireless by nature. In other words, most of the time they are not connected to your router with an Ethernet cable.

That being said, most extenders have an extension function (or access point). This will allow you to connect it to your router using Ethernet.

In extension mode, the WiFi Extender will be faster and have better coverage. But you will have to run an Ethernet cable throughout your house to reach it.

You can also use the Ethernet port to connect to a device.

Let's say that a wired connection to a computer or another device is important to you. In this case, using an Ethernet connection from your extender can be a good choice.

Security

Many WiFi Extenders have built-in security features. For example, some brands have mobile apps with adjustable security tools. This way, you can monitor traffic, start devices, and ensure that you do not have malicious software.

Generally, buying a WiFi extender can be a practical solution to upgrade your wireless network, providing you with the ability to enjoy a reliable connection throughout your home. Factors such as settings, security, coverage, and brand can help you in your purchase.

Don't forget! By considering the above individual characteristics and combining those that fit your needs and usage with your WiFi extender, you can come to the ideal choice for you. Before deciding, you can also take a look at the reviews of other users, to see their opinion and experience, which can help you reach a final decision much more easily.
