10 Effective Ways to Boost Wi-Fi Signal Through Walls: Plaster, Brick, concrete walls

Concrete and brick walls make exquisite materials for building homes. However, they are the worst in the transmission of the signal as they block the movement. They tend to block the signal making it poor beyond the wall or completely missing. As you live in such a house, you may need to know how to boost the Wi-Fi signal through walls.

It is slightly encouraging that some routers manage to pass their signal through thick walls and some that ultimately cannot. However, getting WiFi through brick walls is quite a challenge for some routers.

In our other article, we explored the ways to boost Wi-Fi signals upstairs. This can help you to get better signals upstairs when combined with the tips on this article.

Several things make some signals go through, and some fail to go through. Before getting into creating solutions, it is good to know the reason why signals become poor.

How to boost Wi-Fi signals through walls

Causes of poor penetration of signal in walls

Projection of the signal

The Wi-Fi signal gets projected circularly. On the walls, it fails to maintain the circular motion, therefore, ending up getting blocked. Walls block the movement of the motion and obstruct it because of the insulation layer.

Managing through such walls ends up not happening, and if it penetrates, the signal is usually very weak. Therefore, the projection of the signal is important to ensure it penetrates and reaches the devices beyond the wall.

Choice of material

There is a material that will cause trouble when signals attempt to pass through them. Mirrors, bricks, ceramics, metal, and concrete prove very difficult to let the signals manage through them. Getting WiFi through brick walls and the other material listed here can be daunting.

Reinforced walls that are thick let the signals bounce back, making the connection unreliable. In most cases, having a house with thick walls will give you a poor signal in most rooms.

Router placement

The placement of your router is another factor that makes the wall not penetrable. A good example is when the router is at the wall, and there is an obstacle next to it that begins the hindrance of the connection.

Under such conditions, the connection becomes unmanageable as it does not penetrate the wall next to it and even the one that is far away from it. In addition, locking the router in a cabinet whichever material it is made of, reduces the signal strength.

Number of walls

If you have two walls, there are very high possibilities that the signal will not pass the second wall. The first wall will significantly lower the connection making the second one completely block it.

When there is such an effect, you will notice that your home will have one room with a robust connection and the others with a poor and unreliable connection.

Signal strength

Depending on the signal’s quality, here is one that will entirely not manage through the wall. If the router has its challenges, such as outdated firmware, the signal will not go through the walls.

What also happens when the range between the router and the wall is wide, the signal will get to the wall already inferior hence getting blocked. In this case, the antenna power and technologies such as beamforming can help make the signal stronger.

How to boost the Wi-Fi signal through walls

We all love houses with thick walls. They make the house durable and safer. To ensure that you get a good signal across the wall from your router, you need to make some changes.

Therefore, you can explore ways to boost the Wi-Fi signal through walls. Below are some of the ways that will help you to have the connection getting through your wall.

Use mesh Wi-Fi

Mesh Wi-Fi is a perfect solution to boost your Wi-Fi signal through walls. Mesh Wi-Fi comes with the main router and other small satellites that boost the connection.

The connection devices throw the network between themselves, ensuring that all the space within them is a strong signal.

Therefore, you will have a cloud of connection that will cover the entire area where the devices are located.

The best mesh Wi-Fi is excellent because it finds the quickest route between the router and the device. As a result, you will have a cloud that will surround your home so long as you have adequately spaced the devices.

The signal’s movement is such that it goes around the walls instead of other routers that struggle to go through the walls.

Place the router at a central location

Placing the router next to the walls, router, or other devices contributes to lowering the signal. It is therefore essential to select a central location that will make the connection more robust.

You will have an assurance that the signal gets maintained and is capable of projecting better hence getting beyond the walls. This is important for routers covering a large house.

Selecting a strategic point to place the router is a very important thing. If it is directly facing the point where devices are located, you have an assurance that a powerful signal will get through the wall.

Make sure that the central point you choose does not have obstructions, especially those that are electronic-based. This way, you are sure that you will boost the Wi-Fi signal through walls for whole-home coverage.

The placement is very important when you are using a router for a 2-story house, houses with thick walls, and large houses in general.

Update the router

Sometimes the reason the signal refuses to get through the wall is because of the signal strength. A poor signal could be a result of outdated router firmware. Such a challenge mostly happens when you have a router that has served for some time.

The firmware of a router needs frequent updates because the makers keep improving features the way it happens with editions.

For the router to function well, it needs to be at the most current state. Updating the firmware will therefore make the signal and other features stronger hence making it beyond the wall.

Add an extra external antenna

We cannot ignore the fact that antennas are critical when extending the range and making the signal strength more reliable.

Adding an antenna to the router will make its ability to send signals better. In case your router has a built-in internal antenna, you can consider adding an external one.

A directional antenna makes the ideal solution as it will send signals towards a specific direction. You can have it facing the wall hence making it penetrate through it.

A fantastic thing with the directional antenna is that you can adjust its direction to serve a point better. Chances of dead zones get eliminated since a powerful antenna can boost the Wi-Fi signal through walls.

Enhance your routers security features

There are also very high possibilities that someone is using your internet, making it less effective. When many unauthorized devices are using the connection, there will be limited signals that will not make it through the walls. You will therefore need to make the security features more enhanced so that there is less interference.

The best move is hiding the SSID, which happens to be the name of the network. Anytime you get to a zone that has a Wi-Fi connection, you will see some identities appearing.

When yours is hidden, it does not appear hence making it very safe. As a result, anyone intending to use the network will have to do everything manually.

Get a more powerful router

There are many routers that you can always use to have a better connection. Getting the best long-range router especially with the Wi-Fi 6 technology is a good move as it has features that work on the connection. You can be sure that such a router will have the beamforming technology and the QoS to make signal distribution excellent.

When changing the router, ensure that it covers an extended range. Also, the router should either be a dual-band or tri-band device.  It will deliver a powerful signal that will end up making the connection reach the father’s ends.

A good router will ensure that it delivers a reliable connection to all devices despite their location hence making it through obstacles.

Activate the 2.4GHz band

Having a triband or dual-band router is a fantastic thing. Each band plays a role in ensuring that the connection is stable. The 5GHz band is high-speed, but it will not make it through the wall, especially if it is thick. Its signals, therefore, get instantly blocked as they try to get through the walls.

It is a wise idea to have both the band working together to pick the reliable one. Devices beyond the wall will enjoy the service of the 2.4GHz band because it is powerful when it comes to penetration through the wall.

Invest in Wi-Fi booster

Boosters come as either Wi-Fi extenders or repeaters. A Wi-Fi extender uses the cable to extend the connection and move the Wi-Fi from one room to another using the cobble.

On the other hand, a Wi-Fi extender such as these ones will use the wireless signal to extend the connection range. We have Wi-Fi extenders that are exceptional for different ranges and are compatible with most ISPs. For example, you can pick the best Wi-Fi extender for Xfinity if you are using Comcast high-speed internet.

If the wall is thick and the signal bounces back or very little penetrate, you will need to use an extender. When it is slightly porous, and the signal can make it to the next room, a repeater can be more stable.

Another option of using the repeater is to place it at a strategic position that will enhance the signal’s flow.

Remove any tools standing against the wall

You may have put boards and other items to lean against the wall. These can make outstanding elements that will completely block the connection. What you need to do is to remove the tools that are leaning or next to the wall. 

Ensure that the wall you want the signal to go through does not have any thick item that will make the signal penetration challenging.

In addition, you can use aluminum foil to boost the Wi-Fi signal in a certain direction. This way you can ensure the signals flows towards your devices.

 Prior planning

When constructing walls, you can have a plan that will accommodate your internet needs. Such plans include using the materials that will allow penetration of the signal and the router’s exact location—planning puts the needs of any router that you will buy at any given point.

In addition, you can invest in electrical wiring that can be used for connecting powerline adapters. The best powerline adapter is excellent for gaming, streaming, and other internet intense activities in houses with thick walls.

Conclusion

Signal penetration through walls is quite challenging as it is the biggest obstacle. Walls have different materials with different intensities that make signals fail to go through them. We all want to know how to get WiFi through thick walls.

Reinforced walls are the greatest when it comes to blocking Wi-Fi signals. Assessing to know the real cause of the interfered signals is a lovely thing as it will help you make quick decisions on the solution that will work for you.
