Wifi Extender

What is a WiFi Extender?

A WiFi extender is a device designed to enhance the range and coverage of your existing wireless network. WiFi dead zones can be a frustrating issue in today's connected world, where almost every device relies on stable internet access. These are areas within a home or office where the WiFi signal is weak or nonexistent due to physical obstructions like walls, floors, or distance from the router. A WiFi extender acts as a bridge, capturing the signal from your router and amplifying it to reach areas where the connection would otherwise falter.

One of the primary benefits of using a WiFi extender is its ability to expand your network without requiring additional wiring or complex installation. Once set up, the extender helps maintain a stronger, more consistent connection for devices like smartphones, laptops, smart TVs, and gaming consoles, ensuring you can access the internet anywhere you are within its extended range. This is especially useful in large homes or multi-story buildings where the router's reach may need to be increased to cover every corner.

WiFi extenders also offer a cost-effective solution for improving your home or office network without investing in a new router or a complete network infrastructure overhaul. Many extenders support the 2.4GHz and 5GHz frequency bands, allowing faster data transmission and less interference. While they may not increase your internet speed, they help optimize and stabilize the connection, providing better performance for streaming, browsing, and gaming.

A WiFi extender is a practical tool for anyone looking to eliminate WiFi dead zones and improve wireless coverage in challenging areas. Whether you're working from home, gaming in another room, or trying to stream videos in the backyard, a WiFi extender ensures that you stay connected without interruption, making it a crucial addition to any modern, connected space.

How does a WiFi Extender work?

A WiFi range extender comprises a set of components, typically including two radios with separate receiving and transmitting antennas and networking elements necessary to establish a new wireless router. This latest router is pivotal as wireless endpoints usually communicate with the range extender rather than the primary wireless router. Hence, the range extender typically requires its IP address and network configuration to facilitate communication between the router and endpoints.

The range extender's effectiveness hinges on its placement between the main wireless router and the desired wireless endpoint (or the area where endpoints are located). It only extends the range effectively if it is too close to the main router. Conversely, if it is too distant, the extender may need more data throughput due to weak signals from the router.

Setting up Wi-Fi range extenders is generally straightforward. It often involves simple button presses to establish communication with the primary router. Once connected, endpoints can interact with the range extender as the primary router.

Relaying through the range extender introduces some latency and may slightly degrade the network performance for remote endpoints compared to those near the router. However, this latency is typically minimal and rarely perceptible except in highly latency-sensitive applications.

To illustrate, imagine a baseball game where an outfielder throws a caught ball to home plate via an infielder instead of directly. Similarly, the range extender is the intermediary relay on a Wi-Fi network, facilitating communication between endpoints and the primary router.

How do you know if you need a WiFi Extender?

In current wireless networks, wireless routers function as the central hub, effectively managing many wireless endpoints. Despite this, the fundamental element enabling wireless network operation remains the traditional radio transmitter and receiver embedded in every wireless device. These radio components operate on low power, minimising energy consumption and preventing signal interference with similar devices. This design enables the deployment of multiple devices without encountering interference issues.

Therefore, the choice to incorporate a Wi-Fi range extender should be driven by necessity, which hinges on three primary criteria:

Where does the endpoint need to be?

The allure of Wi-Fi lies in its ability to eliminate the necessity for physical network wiring and grant Wi-Fi endpoints a degree of data mobility within the coverage area. Wi-Fi devices situated on the outskirts or beyond the primary wireless router's coverage zone might require the assistance of a Wi-Fi range extender for optimal connectivity. While range is significant, it's not the sole determinant of wireless network performance. Physical obstructions like walls, doors, and metallic structures can compromise Wi-Fi coverage.

What is the WiFi signal strength in the remote area?

Wi-Fi devices have prominently featured a distinctive icon for years: a bottom point crowned by three expanding semicircles resembling a radar screen. This icon is a universal indicator of Wi-Fi capability and offers a visual gauge of the network's signal strength. The number of semicircular lines corresponds roughly to signal strength, typically increasing in increments of 25%. When the signal strength dips to 25% or lower (equivalent to one or no bars), it suggests a potential need for a range extender to bolster connectivity.

What connectivity does the application need?

Only some applications demand a robust connection. Essential productivity tools like Office 365 often require minimal network bandwidth. In contrast, more demanding applications such as multiplayer games may rely heavily on high bandwidth and low latency for optimal user experience. In cases where these requirements aren't met, deploying a Wi-Fi range extender may become necessary.

It's important to understand that Wi-Fi range extenders are not designed to be interconnected in a "daisy-chain" manner, where one extender communicates with another, forming a chain. While it's feasible to utilise multiple range extenders, each extender must communicate directly with the primary wireless router, serving as the central hub for the network.

What should you consider when choosing a WiFi Extender?

Numerous devices are available in the market to enhance wireless signal coverage. The key to making a successful choice in selecting a Wi-Fi range extender lies in considering three primary factors:

1. Compatibility with Wi-Fi specifications: It's essential to examine your wireless router's Wi-Fi specifications and opt for a range extender that aligns with those specifications. For instance, some of the latest wireless devices utilise the 802.11ax or Wi-Fi 6 standards. While most modern devices are backwards-compatible (automatically reverting to older specs), it's prudent to verify this compatibility before purchasing a range extender.
2. Multi-band functionality: Opt for a range extender that operates simultaneously across two radio bands. This capability enables the extender to enhance performance by utilising different bands for distinct purposes. Additionally, extenders equipped with multiple antennas will allow the device to transmit and receive signals concurrently, improving performance. For instance, a range extender may feature up to four antennas – two for transmitting on different bands and two for receiving on those bands.
3. Consideration of form factor: Consider the placement of the range extender and wireless devices within a home or office environment, selecting a form factor that best suits the deployment location and surroundings.

What are the different types of WiFi extenders?

There are various methods of connecting a wireless range extender to a primary wireless router and different form factors to consider.

1. Wireless Range Extender: The most common range extender operates wirelessly, requiring only an AC power connection. These devices transmit and receive Wi-Fi signals entirely over the air.
2. Powerline Adapters: This method utilises AC electrical wiring within a home or office to supply power and carry network signals. The main router connects to a companion powerline adapter via a port. Since powerline adapters don't rely on a wireless connection to the main router (only from the adapter to endpoint devices), they can be situated farther away from the router.
3. Coaxial Adapters: Like powerline adapters, coaxial (MoCA) adapters with Wi-Fi utilise coaxial cabling in a home or office to establish wired connections to remote adapters. These adapters can then leverage wireless capability to provide Wi-Fi coverage. Some MoCA devices may offer only a wired Ethernet LAN port. The main router is typically connected to a coaxial port linked to the internet service provider (ISP).

Additionally, consider the deployment location for the Wi-Fi range extender:

• Desktop: A desktop form factor is typically placed on a desk or shelf and powered via an AC adapter.
• Wall AC: This form factor plugs directly into an AC outlet, keeping the device low-profile and inconspicuous.
• Outdoor: Certain devices are designed and sealed for harsher environments, and they are suitable for outdoor deployments in dusty, hot/cold, or humid conditions.

How to set up a WiFi Extender?

Setting up a WiFi extender is a relatively simple process that can dramatically improve the reach and strength of your wireless network. The goal is to place the extender where it can receive a strong signal from your router and amplify it to cover areas with poor connectivity. While the exact setup steps may vary depending on the brand and model of the extender, the process generally follows a similar pattern.

The first step is to find the right location for your WiFi extender. Ideally, this should be halfway between your router and the area where the WiFi signal is weak or nonexistent. Placing the extender too far from the router can result in it not receiving enough signal to extend effectively. Once you have a location in mind, plug the extender into an electrical outlet and ensure it is powered on.

Most modern WiFi extenders are designed for easy setup, often offering two primary methods: WPS (WiFi Protected Setup) and manual configuration. If your router supports WPS, press the WPS button on both your router and the extender. This will establish a secure connection between the two devices automatically. If your router doesn't support WPS, you must manually connect using your smartphone, laptop, or desktop. In this case, you'll typically connect to the extender's temporary network and then use a web browser to access its setup page. From there, you'll be prompted to select your existing WiFi network and enter its password, allowing the extender to replicate and boost your router's signal.

Once the extender is connected to your network, it's essential to check the signal strength. Many extenders have indicator lights or companion apps that help you determine whether they are receiving a strong signal from the router. Adjust the extender's position if necessary, ensuring it's in a location that balances proximity to the router and coverage of the target area.

After the setup, you should notice a significant improvement in your network's range and stability. Devices that previously struggled to stay connected in certain areas should now have more robust, more reliable WiFi.

WiFi Extender vs. WiFi Repeater vs. WiFi Booster.

In wireless networks, terms like extender, booster, and repeater are often used interchangeably due to their shared purpose of enhancing wireless connectivity in areas with poor or non-existent service. While they serve similar functions, technical distinctions exist among those seeking precision in terminology. However, for the sake of this discussion, these terms can be used interchangeably.

Extender: Typically, a range extender establishes a wired connection between the router and itself using an adapter, extending wireless coverage to its vicinity. Some extenders utilise powerline technology for this wired connection.

Repeater: In contrast, a repeater relies solely on wireless connectivity to link with the router. Its primary function is to amplify and retransmit signals more robustly, improving Wi-Fi coverage for nearby endpoints.

Booster: The term "booster" is more ambiguous, as it can refer to either an extender or a repeater, potentially confusing discussions about network devices.

A range extender is a compact device equipped with multiple independently adjustable antennas to receive and transmit wireless signals. While some extenders can be placed on desks or shelves using wired AC adapters, many are designed to plug directly into wall outlets, enabling inconspicuous placement within a building.

Where to place a WiFi Extender?

Placing a WiFi extender in the optimal location is crucial for effectively boosting your network's coverage. The primary purpose of a WiFi extender is to receive the existing signal from your router and amplify it to cover areas where the connection is weak. However, simply plugging the extender in without considering its placement can result in poor performance or minimal improvement in coverage.

The best location for a WiFi extender is typically halfway between your router and the area where you experience weak or no WiFi signal. This allows the extender to capture a robust and stable signal from the router while extending it to the dead zones. Placing the extender too close to the router will expand the range more effectively, as there's no weak area to cover. On the other hand, placing it too far from the router may result in the extender receiving a weak signal, which will lead to poor performance, as it can only amplify the signal strength it receives.

It's also important to avoid physical obstructions. Large walls, furniture, and appliances like refrigerators or microwaves can interfere with the WiFi signal. For optimal performance, place the extender in an open space, preferably at an elevated height, like on a bookshelf or wall mount, to reduce interference from obstacles. If your home has multiple floors, placing the extender in a stairwell or open hallway can help spread the signal evenly across different levels.

Many WiFi extenders come with signal strength indicators, which can help you find the perfect spot. These indicators, either on the device itself or within a companion app, will show how strong the connection between the router and the extender is. Adjust the extender's placement until you find a location that captures a strong signal from the router while effectively covering the target area.

The placement of your WiFi extender plays a significant role in its ability to boost your network's performance. A central, open location that balances proximity to the router with coverage of the dead zones will help ensure you get the most out of your WiFi extender, providing reliable, high-speed internet access throughout your home or office.
