Do Internet Extenders Actually Work?

Having to deal with a slow or spotty Wi-Fi connection can be quite the hassle, particularly when working from home, gaming or watching a movie. One of the most common devices in this situation is Wi-Fi extender. These devices promise enhanced coverage and removal of internet dead zones. The real question is, do they actually achieve their intended purpose or is there a better alternative?

What is the Purpose of an Internet Extender?

An internet extender is a device that improves your coverage by rebroadcasting the signal from your router. The goal is to enhance internet connectivity in a premises and provide network to ‘no signal’ zones. They are often used in large homes or premises to provide internet coverage to upstairs bedrooms, basements or outdoor areas.

How Do Wi-Fi Extenders Work?

Rather than establishing a brand-new network connection, the extender connects to the existing Wi-Fi and distributes the signal in its vicinity. The device acts as a communicator to help the router and your device talk and provide a signal in low-connectivity zones.

Why Choose a Wifi Extender?

Wi-Fi extenders are a cheap alternative to expanding connectivity in your home or business venue. These devices are simple to install and configure. They are highly reliable for eliminating dead zones and are particularly useful in large residences, homes with thick walls and office spaces.

Are There Other WiFi Boosters?

There are mesh Wi-Fi systems that utilise multiple nodes to provide seamless coverage throughout your entire home, as well as powerline adapters that transmit internet signals through your home’s electrical wiring. While these options may deliver stronger performance, they tend to be pricier than standard extenders.

How to Choose the Best Wi-Fi Extender for You

When choosing a Wi-Fi extender, it is important to think about its compatibility with your current router, the supported standards (Wi-Fi 5, Wi-Fi 6, etc.), speed rating, range coverage, installation ease and additional features such as Ethernet ports. Below is a simple list of things to consider:

✓ Check Compatibility

To avoid performance disruption, ensure the extender supports the router’s standard Wi-Fi Grade (Wi-Fi 5, Wi-Fi 6, etc.).

✓ Consider the Coverage Area

Pick a model that covers the area of your home/office, particularly if there are multiple levels or thick walls.

✓ Look at Speed Ratings

If you often stream, game or work online, select a dual or tri-band extender that has higher Mbps rating.

✓ Extra Features

Some models are more versatile and user friendly because they include Ethernet ports and other features such as app-based configuration.

✓ Ease of Setup

Look for models of extenders having either very simple plug-and-play installation procedures or mobile apps that allow for very simple setup and configuration.

Do Extenders Slow Down the Internet?

Some extenders can slow down the internet and other devices because they repeat the signal, although new modern dual-band models have started to minimise this issue by having one band that talks to the router and the other to the devices.

How to Increase Wi-Fi Coverage with Good Extender Placement

• Halfway Point: Place the extender at the midpoint between the router and the zone that does not receive signal.
• Strong Signal First: Position the extender where it can receive a good connection with the router.
• Clear Obstructions: The extender should not be placed near appliances that interfere with signals like thick walls, metal objects and microwaves.
• Place in High Position: An extender should not be placed on the floor otherwise good coverage won’t be provided. Shelves or other surfaces that are elevated are ideal.
• Adjust and Test: Move and adjust the location of the extender and check signal strength with your device to gauge where speeds are not improving.
