“How to increase WiFi signal through walls”: Brick and concrete walls are ideal for building solid houses. However, these materials inhibit signal transmission and block movement. So you can’t enjoy off-wall Wi-Fi in other rooms of the house. So if you have a large house with a weak WiFi signal, you should learn how to boost it.
The good news is that some routers can pass signals through thick brick walls, while others cannot. Either way, this task is equally difficult for all efficient Wi-Fi routers.
But don’t worry, because you can improve WiFi signal transmission through walls by installing better devices, overcoming signal interference, and locating WiFi repeaters correctly.
This article offers advice on boosting your WiFi signal even through brick walls. So let’s take a look.

Factors that Impede Wifi Travelling Through Walls

Wireless Signal Projection

Have you ever wondered how the WiFi signal travels from the WiFi repeater to your device?

The wireless signal is projected in a circular motion. However, these signals do not maintain circular motion when passing through thick walls.

This results in the blocking of the Wi-Fi signal. But why does this happen?

Because the walls have insulation layers that impede or prevent signal transmission, Wi-Fi signals cannot pass through these walls. And even if they do, their power is pretty weak. That’s why it’s essential to project Wi-Fi signals outside of walls to help them get through and reach your devices.

Material Selection

Some of the materials used to build the wall result in a weak Wi-Fi signal. These documents typically include the following:

  • Ceramics
  • Brick
  • Mirror
  • Concrete
  • Metal

All these materials make it difficult for signals to travel through walls. Also, reinforcing the signal with brick walls and other materials listed above is a big challenge. Because they bounce off the signal, your Internet connection will be unreliable, low quality.

Router location:

Your router’s location is important for a stable Wi-Fi signal. Indeed, if your router is placed near obstacles and other substances, your Internet connection may suffer. Also, routers that are located far from the room will make it difficult for the signal to reach your device. Also, placing your router in a cabinet or locker can adversely affect signal strength.

The number of walls:

Let’s say you’re sitting in a room two walls away from your Wi-Fi router, in such cases the WiFi signal can suffer when moving from one brick wall to another. As a result, you’ll get a relatively better signal in one area of ​​your home, while other areas may have poor and unstable Internet connections.

Signal strength:

Your Wi-Fi signal strength also plays an important role in determining signal transmission. For example, if you get a weak signal from your carrier, they won’t go through a thick wall. In addition, issues such as faulty or outdated firmware can also lead to poor Wi-Fi signal quality.
However, you can solve this problem with devices with better technology and better antenna sources.

How to boost the WiFi signal through the wall?

Now that you know what could be affecting your signal strength, it’s time to fix those issues. And for that, you can try some of the following troubleshooting steps. These methods can help boost Wi-Fi signals through thick walls, from updating your router to using an external antenna.

Using mesh Wi-Fi:

Mesh Wi-Fi can be a great solution to boost signal strength through brick walls. It includes the main router along with other smaller satellites that can stabilize your connection.
The Asus Zen WiFi AX XT8 is a great Mesh system with excellent reviews. It delivers efficient performance and has parental controls that can last a lifetime. Moreover, it has security software for your WiFi network to protect it from cyberattacks. In addition, it allows you to connect multiple devices with multi-gigabit LAN and USB ports. These devices can include smart TVs, game consoles, and more.
Mesh WiFi systems ensure a strong WiFi signal throughout your home by establishing a connection between all connected devices. This way no space is used. You’ll be able to enjoy a WiFi network that covers your entire home.
Also, with this WiFi system, the signal can discover the fastest route from your current router to your device. Therefore, the signal can travel around the walls instead of trying to go through them.

Set your router correctly:

Signal strength can be reduced by placing routers near walls, appliances, and other routers. Therefore, it is very important to choose a central location away from other obstacles to increase the WiFi signal. This will ensure that your signal will be projected correctly and your device will be able to receive a stable Internet connection beyond thick walls.
Additionally, determining the right place to install a WiFi router can help you project a reliable signal in larger homes. So if you put your router right in front of all connected devices, you can have a stable Internet connection.

Update router firmware:

A weak and poor signal can hardly go through thick walls. As a result, you will experience a blocked or unstable WiFi signal. This can be caused by outdated or faulty firmware. So, if your current router has been working for several years, it’s time to buy a new one.
Furthermore, manufacturers continue to modify their routers with the latest technology and release new versions from time to time. Therefore, you need to update your router to keep up with changing technology and Internet speeds. Also, updated and newer routers may perform better than older routers. And it can emit a stronger, more reliable WiFi signal that can easily penetrate concrete or brick walls.

Install an external antenna:

Antennas are essential to extending the WiFi signal range and increasing signal strength. Therefore, their importance should never be overlooked.
Adding an external antenna can improve your router’s ability to send better signals. And if you already have a built-in antenna inside your router, consider adding an external antenna. In addition, directional antennas are ideal for projecting signals in a specific direction. For example, mounting the antenna towards the wall will allow the WiFi signal to pass through it quickly. Additionally, these antennas can adjust their orientation to serve different areas of your home. Therefore, you are unlikely to have a dead zone when there is no internet connection in your entire house.

Improve your router’s security features

When a picture or other object is propped up against a wall, the WiFi signal could be weaker. But what if there are too few people sharing the Internet at your home? Is someone stealing your WiFi? If so, your WiFi signal may be unstable and lead to a poor Internet connection. And since a weak signal can’t penetrate thick walls, you may find yourself without Internet in certain areas of your home. Therefore, you should update the security features of your Internet connection to eliminate outside interference.
A great way to get the job done is to hide your SSID. Your network name appears whenever someone searches for available WiFi connections. If the name is concealed, it might not show up in the networks that are accessible. As a result, your connection can be protected from outside interference.

Buy a powerful router:

For example, a router with WiFi technology is the ideal long-range router. These routers improve the WiFi signal’s capacity to increase its range inside your house. Furthermore, they can guarantee an incredible quality of service thanks to beamforming technology. So the next time you consider buying a new router, make sure it can work on an extended range. In addition, your router must have a tri-band or at least dual-band connection for you to enjoy the maximum Internet signal.

Activate the 2.4 GHz band:

Installing dual or tri-band routers is great because they provide a stable Internet connection. But have you ever wondered if 5 GHz Wi-Fi can penetrate walls?
Well, the 5GHz WiFi band can give you a high-speed signal. However, these signals are immediately blocked and cannot penetrate thick brick walls.
So it’s best to choose what works best for your home using both WiFi bands. This is because gadgets and wireless devices outside the wall may require a stable 2.4 GHz connection instead of the impenetrable 5GHz Internet.
In addition, using both bands together can allow you to enjoy reliable Internet speeds at any distance in your home.

Get a Wi-Fi booster:

WiFi booster or WiFi repeater is a device that has the ability to repeat or extend your WiFi signal. They use cables to extend the WiFi connection and allow the signal to travel through your house through the cobblestone.
A WiFi repeater utilizes a wireless signal to extend its range. In addition, they are compatible with several ISPs and WiFi ranges. So, for example, you can pick up the awesome Xfinity accelerator for Comcast Internet.
In addition, extension cords can help transmit signals through thick walls. Remove tools from your wall: Indeed, penetrating thick walls is a challenge in itself, while elements present in other objects in the home further reduce Internet connectivity. Therefore, you should remove any tools or objects that are on the walls of your room.
Also, you should check if your walls are covered with thick material, as it can hinder your internet speed. Finally, using aluminum can increase the range of your signal in specific directions.

Planning ahead:

When building walls for your internet needs, you need to plan. This may include preparing a material that will allow the signal to easily pass through the brick wall. Also, you need to choose your WiFi router wisely and place it in ideal locations. Alternatively, you can invest in wiring to connect your power line adapters. These adapters are suitable for streaming, gaming, and other intense Internet use in homes with thick walls.

How to use a second router to increase your WiFi range.
