Why Strong Wi-Fi Through Walls Matters

Walls, quite literally, can stand as barriers between us and seamless connectivity. Whether they’re made from concrete, stone, or even just drywall, walls can disrupt our Wi-Fi signal. The denser the material, the more resistance the wall poses to radio waves, leading to a weakened Wi-Fi signal.

The Importance of Strong Wi-Fi in Homes

In today’s world, our homes are not just places for us to live, but are also our offices, entertainment hubs, and learning environments. This shift has made strong Wi-Fi through walls an absolute necessity. Here are some circumstances where boosting your internet in your home may be crucial.

Working from home

With the rise of remote work, many of us rely on home offices to stay productive. A reliable Wi-Fi connection is non-negotiable in these spaces. You need to be able to ensure that important video conferences, emails, and collaborative work tools function smoothly.

Living in a multi-story home

In multi-story homes, the challenge of maintaining a strong Wi-Fi signal becomes even more evident. As you add more walls and floors, your Wi-Fi signal faces more obstacles, impacting your internet experience. 

Smart home connectivity

If you have smart home features, you need a strong Wi-Fi signal in all corners of your home. From smart thermostats and lighting systems to security cameras, a reliable signal ensures that these systems work as intended.

Now that we’ve recapped the significance of strong Wi-Fi and the challenges posed by walls, let’s explore some practical solutions you can implement today to enhance your internet signal strength without breaking the bank. 

DIY Ways to Strengthen Your Wi-Fi Signal

To optimize your home Wi-Fi signal, here are some do-it-yourself (DIY) methods. These steps will help you assess and enhance your Wi-Fi connectivity without the need for expensive upgrades.

Check Your Wired Internet Connection

Before diving into Wi-Fi signal improvements, it’s crucial to establish a baseline by checking your wired internet connection. A reliable wired connection provides a reference point for assessing Wi-Fi performance. If you’re not techie enough to use and understand Wi-Fi signal visualization software, here is how to do it easily:

Step 1: Connect a device directly to your router using an Ethernet cable. This eliminates any potential Wi-Fi-related issues.

Step 2: Run a speed test to measure your wired internet speed. 

Step 3: Document your wired connection speed. This will serve as a benchmark for future comparisons.

To simplify this process for you, we’ve prepared a troubleshooting guide to help you diagnose any potential issues.

Determine Areas with Weak Signal

Next, we need to identify areas in your home with a weak internet signal. To do so, simply walk around your home with a device connected to your Wi-Fi network. Pay attention to signal strength indicators on your device. If you lose bars on your signal indicator, you know you’re losing Wi-Fi performance in that area. 

Run a speed test in each of these weak signal areas to see how far off your benchmark speed you are, and to establish a baseline for future comparisons.

To assist you in tracking your signal strength, here’s a guide to test your signal strength. After identifying areas with weak signals, it’s time to take some simple steps to fix this issue.

Change Router Location

The placement of your router plays a pivotal role in signal strength; make sure your router is located in a central location within your home. This minimizes the impact of walls and obstacles on signal strength. 

As we mentioned earlier, walls, especially those made of denser materials like concrete, can significantly weaken Wi-Fi signals. By centralizing your router, you reduce the number of barriers the signal has to overcome.

Another factor to keep in mind when considering router location is an area free of any objects or obstructions that may block the signal. This can be furniture, decor, or any other object (especially metal) that is standing between your router and your device.

If your router is already located centrally within your home, there’s another simple step you can take, and it involves a product you likely have in your kitchen right now: aluminum foil.

Using Aluminum Foil to Boost Signal

Surprisingly, aluminum foil can serve as a budget-friendly Wi-Fi signal booster. Because of its reflective properties, aluminum foil can reflect and localize your Wi-Fi signal in a specific direction. By strategically placing some foil behind your router, you can direct the signal toward the dead zones in your home.

Be cautious, though: When using aluminum foil, try to avoid overheating your router. Ensure that the foil does not touch any electrical components and is used solely to reflect the signal.

Update Router Firmware

Just like you need to regularly update your cell phone or tablet, you also should regularly update your router firmware. Keeping your firmware up-to-date is crucial for top performance and security.

Check your router manufacturer’s website for the latest firmware version. Follow their step-by-step guide to download and install the update.

Change Your Wi-Fi Frequency

Most modern routers offer two frequency options: 2.4 GHz and 5 GHz. 

The main difference between these two frequencies lies in their signal coverage range and speed capabilities. The 2.4 GHz band offers a broader coverage area but at a lower maximum speed. The 5 GHz band provides less coverage but boasts higher throughput potential. 

If your device is far from your router, opt to join the 2.4 GHz band (it should specify 2.4 GHz in the network name). However, if you are near your router and prefer superior performance and speed, join the 5 GHz band.

As an additional note, the 5 GHz band is better at cutting through network clutter and interference, optimizing network performance. This makes it the ideal choice for gamers to reduce game lag and ensure a smoother overall experience.

Remove Wi-Fi Intruders

Unauthorized access to your Wi-Fi network can not only slow it down, but also poses some serious security risks. Unauthorized users can consume your bandwidth, leading to slower speeds. Additionally, these users can get access to your sensitive information like passwords, credit card information you’ve filled in online, etc.

To address this issue, begin by ensuring that your Wi-Fi is password-protected with a password that’s not easy to guess. To identify any unauthorized users, access your router’s settings and view connected devices. Identify any unfamiliar devices and disconnect them from your network.

Control Quality of Service

Quality of Service (QoS) settings on your router can prioritize certain types of traffic over others. This can be beneficial for maintaining a strong connection when multiple devices are in use.

QoS settings allow you to direct more bandwidth to essential tasks. For example, you can set your QoS to prioritize video conferencing when working from home to ensure a smoother experience.

Adjust Your Antenna

Finally, consider adjusting or upgrading your router’s antennas. Different antennas can impact your signal range and direction. 

Some routers come with detachable antennas, allowing you to replace or add antennas for better coverage. Check your router manufacturer’s website for information on how to add or replace your router antennas. 

By exploring these DIY methods, you can take proactive steps to strengthen your Wi-Fi signal without breaking the bank. If you’ve taken the steps in this section and are still struggling with poor Wi-Fi signal, it may be time to explore some paid solutions. In the next section, we’ll highlight some solutions that are a bit more costly, but also more effective.

While DIY solutions can work wonders, there are times when investing in internet speed boosters is necessary. In this section, we’ll explore paid methods that can significantly boost your Wi-Fi signal strength.

Use a Mesh Network to Boost the Wi-Fi Signal

One of the best ways to boost your Wi-Fi signal is to invest in a mesh network. A mesh network is designed to eliminate dead zones and provide seamless coverage throughout your home. 

Unlike traditional routers, which rely on a single access point, mesh networks consist of multiple wireless access points. These access points work together to create a unified Wi-Fi network, giving you strong Wi-Fi in every corner of your home.

Several reputable brands offer wireless access points to make up your home mesh network, including Google, Eero, and Asus. These systems come in various configurations to suit different needs and budgets. Here are some options depending on your budget:
