Get ready to optimize your wireless network and say goodbye to signal drop-offs, because we’re about to reveal the secrets to boosting your WiFi signal through walls!

Why is Wi-Fi blocked by walls?

WiFi signals can be blocked or weakened by walls due to several reasons:


Different building materials, such as concrete, brick, metal, or thick plaster, can absorb or attenuate WiFi signals. As the signal passes through these materials, it loses strength. The denser the material, the higher the attenuation, resulting in a weaker WiFi signal on the other side of the wall.


Some walls, particularly those made of smooth and reflective materials like glass or mirrors, can reflect WiFi signals. When signals bounce off these surfaces, they can scatter or interfere with the original signal, causing degradation or dead spots in certain areas.


Certain materials, like water or insulation, have the ability to absorb radio waves, including WiFi signals. If your walls contain moisture or have dense insulation, they can absorb a portion of the WiFi signal, leading to weaker signal strength.


Walls can create interference by obstructing the direct line of sight between the WiFi router and the receiving device. Interference occurs when the signal has to pass through multiple walls, furniture, or other obstacles, which can scatter or distort the signal, resulting in reduced signal strength or packet loss.


As WiFi signals travel through the air, they naturally weaken with distance. When the signal has to pass through walls, the additional distance adds to the attenuation, making the signal even weaker by the time it reaches the other side.

Why should you boost your wifi signals?

Boosting your WiFi signals offers several compelling advantages that can significantly enhance your online experience. Here are some reasons why you should consider boosting your WiFi signals:

How to boost wifi signal through walls?

Boosting your WiFi signal through walls may seem like a daunting task, but with a few strategic adjustments and the right tools, you can significantly improve your wireless network’s performance. Here are some effective ways to overcome the obstacle of walls and enhance your WiFi signal:

Optimize Router Placement: 

Start by positioning your WiFi router in a central location within your home. Avoid placing it near walls made of thick materials like concrete or metal, as these materials can obstruct the signal. Experiment with different locations and angles to find the optimal placement for maximum coverage.

Reduce Interference: 

Electronic devices such as cordless phones, baby monitors, microwave ovens, and Bluetooth devices can interfere with your WiFi signal. Keep your router away from these devices, or consider upgrading to a dual-band router that operates on the less congested 5 GHz frequency.

Update Firmware and Settings: 

Ensure that your router’s firmware is up to date. Manufacturers often release firmware updates that improve performance and fix bugs. Additionally, access your router’s settings and adjust channel settings to minimize interference from neighboring networks.

Use WiFi Range Extenders: 

WiFi range extenders, also known as WiFi boosters or repeaters, can help amplify your signal by extending its range. Place a range extender strategically between your router and the areas with weak signal strength to bridge the gap and enhance coverage.

Upgrade to a Mesh WiFi System: 

Mesh WiFi systems consist of multiple nodes that work together to create a seamless wireless network. By strategically placing nodes throughout your home, these systems can overcome the barrier of walls and provide consistent WiFi coverage in every room.

Utilize Powerline Adapters: 

Powerline adapters use your home’s electrical wiring to transmit data signals. By connecting one adapter to your router and plugging another adapter into a power outlet near the weak signal area, you can extend your network through the electrical circuitry and overcome wall barriers.

Install a WiFi Repeater or Access Point: 

Similar to WiFi range extenders, WiFi repeaters or access points can be strategically placed to extend your network’s coverage. They capture and amplify the existing WiFi signal, effectively penetrating walls and ensuring a strong connection in hard-to-reach areas.

Consider WiFi Antennas: 

Upgrading your router’s antenna to a higher-gain or directional antenna can help focus and amplify the WiFi signal in specific directions. This can be particularly useful if you’re trying to overcome walls in a specific area of your home.

Does wifi signal affect Internet speed?

Yes, the WiFi signal can affect internet speed. The WiFi signal is responsible for wirelessly transmitting data between your devices (such as smartphones, laptops, or smart TVs) and the router, which is connected to the internet service provider (ISP). The strength and quality of the WiFi signal can impact the speed at which data is transmitted, thus affecting your overall internet speed.

Here’s how a WiFi signal can affect internet speed:

Signal Strength: 

The strength of the WiFi signal determines how effectively data is transmitted between your device and the router. If the signal is weak, due to distance, obstructions, or other factors, the data transmission speed may be slower. As the signal strength decreases, the speed and reliability of your internet connection can diminish.

Signal Interference: 

WiFi signals can face interference from various sources, including neighboring WiFi networks, electronic devices (e.g., cordless phones, microwave ovens), or physical obstacles (e.g., walls, furniture). Interference can disrupt or weaken the WiFi signal, resulting in slower internet speeds and potential connection drops.

WiFi Network Congestion: 

If there are multiple devices connected to the same WiFi network, the available bandwidth is shared among them. When many devices are actively using the network simultaneously, it can lead to congestion and reduced internet speeds for each connected device.

WiFi Standards and Frequencies: 

Different WiFi standards (e.g., 802.11n, 802.11ac) and frequencies (e.g., 2.4 GHz, 5 GHz) offer varying speeds and performance capabilities. For instance, 5 GHz frequencies generally provide faster speeds but have a shorter range compared to 2.4 GHz frequencies. The WiFi standard supported by your devices and router can impact the maximum potential speed you can achieve.

How to check wifi signal strength?

To check your WiFi signal strength, you can use the following methods:

WiFi Analyzer Apps: 

There are various WiFi analyzer apps available for smartphones and tablets that provide detailed information about WiFi networks, including signal strength. These apps can provide real-time signal strength measurements, as well as display graphs and charts to visualize signal quality. Some popular WiFi analyzer apps include “WiFi Analyzer” for Android and “WiFi SweetSpots” for iOS.

Router Web Interface: 

You can access your router’s web interface to check the WiFi signal strength. Open a web browser on a device connected to your network and enter the router’s IP address (usually printed on the router or mentioned in the documentation). Log in to the router’s admin interface, and depending on your router’s firmware, you should find a section displaying the WiFi signal strength or related information.

WiFi Signal Testing Tools: 

Several online tools can measure your WiFi signal strength. These tools typically require you to visit a specific website on a device connected to your WiFi network, and they will display the signal strength measurement. One example is “Speedtest by Ookla” (, which provides not only internet speed testing but also information about your network’s signal strength.

When checking WiFi signal strength, keep in mind that signal strength is typically represented by bars, a percentage, or a numerical value. The higher the signal strength, the better the connection quality. If you notice consistently low signal strength, you may need to consider improving your WiFi setup by adjusting the router placement, using WiFi extenders, or addressing sources of interference to boost the signal strength and improve your wireless network’s performance.
