How to Block Wi-Fi in a Room- 10 Simple methods

Sometimes having to block Wi-Fi in a room becomes essential. The primary reason that may lead to the blocking of such signals is to ensure that there is no interruption for the activities that will be happening in the room.

People get distracted with their phones and other devices when they are in a meeting room or someplace where they need to focus on something. You might be able to solve this problem by just asking them not to use the phone, but that is not always going to work. If you want people in your office or home to stay off of their phones while in a certain area, then you will have to block Wi-Fi signals from reaching those areas.

Some good examples of rooms that you can block Wi-Fi are the health rooms and classes, especially when exams are ongoing. You can also block Wi-Fi from bedrooms in your home for device-free nights and other reasons.

Some people will also choose not to have Wi-Fi in their rooms because they want less interruption when doing their tasks. Blocking the connection can be slightly challenging, but it is something you will quickly and conveniently do. There are various methods that you can use to ensure that no signal gets to a specific room.

What are good internet speeds? And to ensure these speeds, where do you place the WiFi router in your house for the best coverage? The router should be positioned centrally away from obstacles and interference. And finally how to block Wi-Fi in a room to ensure less interruptions

Why block Wi-Fi in a room

Each person has a specific reason as to why they need to block Wi-Fi signals. Some do so because they want a conducive environment, and some consider their health status. The following are some of the reasons why people choose to block Wi-Fi signals.

Maintaining health

Some people are conscious about their health and consider having the waves not reaching the rooms. However, the waves have EMFs that penetrate through walls and can be a little bit dangerous.

Some people are exposed and switch off their electronic devices. However, even after switching the Wi-Fi off, there is still danger from Wi-Fi signal from their neighbors hence the need to block them.

Reduce interruption

You may have a connection that is not functioning as you expect. One of the major causes of this challenge will be the signals that come from the neighboring connections. Some can be very strong hence causing noise in the room. If you choose to ensure that the connection you have gets less effect from the parties outside the room’s environment, you will be very safe.

Increase productivity

Wi-Fi connection brings addiction to some people. When they operate within an area with a Wi-Fi connection, their work productivity lower, making the daily achievements unrealistic. Blocking the signals from getting to the specific areas goes a long way to boost the person’s productivity.

Phone and internet interruption also lowers significantly when you limit the connection and Wi-Fi performance. You will also enjoy that you enjoy productivity improvements when people have a specific objective and mission to achieve.

Improve the connection

If you have two rooms with a connection and one has many devices, you can block the other from getting Wi-Fi. The outcome is that the devices that are operating inside the room will enjoy a quick and stable connection.

The property that makes the connection speeds lower remains stable, making your devices enjoy high speeds and reliable connectivity. Moreover, the chances of having your neighbors using your connection also get entirely limited hence boosting the productivity of the router.

Limit the children use of devices at other times

Children and teenagers are quite cheeky these days. They can lock themselves in their bedrooms or other corners of the house to explore the internet. This means that you will have no power to vet the material or limit the time that they are online.

If you do not have the best parental control router or if your children have learnt how to bypass it, you can block Wi-Fi from their room or other places in your house. This will ensure that you have control over the exposure period and materials accessed.

Protect the connection

Blocking the connection in a room goes a long way to make the connection secure. One thing you will have great moments with is the guaranteed safety that the router offers. Hackers and online predators get eliminated hence making the connection fast and more reliable.

If you have children using the connection, you will have an assurance that anyone attempting to get to the connection does not get a chance to do so.  Your devices also remain safe as they can operate freely within the range that it operates from.

Methods that block Wi-Fi in a room

Blocking Wifi in a room can be done easily and here we have listed some ways to do it for you. These methods will help you in blocking wifi in any place, especially the rooms where there should not be any interruption or disturbance as such.

Here are some simple ways by which one can easily block WiFi signal on their own and enjoy uninterrupted time without being disturbed by others who might use the same internet connection at home, office or anywhere else they go to.

There are various methods that you can comfortably use to block Wi-Fi in a room and most of them require only one piece of equipment.

Use Ethernet routers/ connections

The first option is using an Ethernet cable for each device that needs internet access. This may seem like overkill if there is only one person per room, but it can still be effective if someone else has a laptop nearby trying to connect through wireless signals as well.

Using an Ethernet router makes it hard to connect devices when you are not in close proximity to the Ethernet cable. You can also not connect to your devices if they are not wired devices.

Therefore, you can use an Ethernet cable to connect devices in a room where you want to block Wi-Fi. This means some devices will still be connected depending on the requirements.

Choice of frequency

The 5GHz band operates at very high speeds but poor in allowing signals to get through the wall. On the other hand, the 2.4 GHz band is slower but with great potential when penetrating through the walls. Connecting many devices on the 2.4 GHz band will lower the quality of the connection significantly.

For fast devices, you can use the 5GHz band so that they perform to the maximum. A better choice is to disable the 2.4GHz band hence making the speeds lower drastically. If it is not active, the signal will have less strength to get through the walls hence maintaining the room.

Construction of concrete walls

Wi-Fi and concrete are like paraffin and water. It is a thick material that you can conveniently use to have a better and stable connection. But, unfortunately, signals have a very hard time when they need to get through thick and concrete walls.

When constructing such a wall, you will have to consider having a thickness to make penetration harder. Thicker walls make a connection not easy, even when you use Wi-Fi extenders. In addition, such walls will block the incoming Wi-Fi signal and one that is within the room.

Install and use Metal products

Metals have the greatest potential to block the Wi-Fi signal because of their ability to conduct electricity. In addition, the ability to absorb radio and electromagnetic waves are great, which means that your connection will bounce back and not attempt to penetrate through the walls with metals.

If you choose to use metal walls, doors, and other infrastructure, the connection will remain stable all through. However, choosing to place a router at a specific point with the metal objects, the connection will bounce back hence terminating the signal. In addition, the presence of such materials at strategic points will also make the connection more unreliable.

Finally, it is easy to use aluminum foil to boost Wi-Fi by directing it where it is required. Thus, you can also use it to ensure the signals do not move in the direction of the room where you want to block Wi-FI.

Plaster and metal lath

This material is one that you will comfortably use on the floor and the walls. It is not very thick but has great potential that slows the connection speeds. The quality of the signal also lowers when you have connected the devices as the material makes it difficult to maintain the quality.

When you use this material, you will have 1/8 inch for the thickness in floors and 5/8 inches for the thickness on the walls. If you are building a modern building or structure, you can consider making use of this material. Apart from working on the walls and floor, you can choose to use it on the ceiling as it delivers excellence.

Ceramic tiles

The combination of materials used in the installation of ceramic tiles makes an ideal choice because it entirely blocks the signal making it unreliable. Mastic is the material that is used in the installation of the tiles and makes the walls and the floors capable of managing the Wi-Fi signal

If your house has multiple floors, this material will entirely block the signal from getting to the below and above rooms. Using it on the walls will also prevent the penetration of the signal to the next rooms hence making the connection more reliable.

Work on the windows

You can have very strong walls and then have the signal getting through the windows. So it is important to have the windows with material that will also help to improve the connection. Windows are transparent and will let the light pass through them, but the glass’s choice is the determinant.

Windows are capable of blocking the Wi-Fi signal, especially if you make use of the low-emissivity windows. If the glass is tinted, the ability to block the signal becomes better. The combination of the metallic film and the windows’ colour help manage the signal strength, hence preserving the connection.

Choice of mirror

Just like glasses, mirrors can reflect. When connected, the signal also bounces back, making it impossible to have it through the walls. Any mirror has a metal backing that is responsible for electromagnetic interference hence making the waves bounce back.

If you have a mirror wall, the signal will bounce and won’t be as powerful as the decorative mirror. Therefore, you can reinforce your walls with mirrors, hence boosting the connection and the ability of the signals to bounce back.  You can also put the mirrors around the wall hence boosting the ability of the router to block the electromagnetic waves.

Choice of appliances

Electronic appliances are very good because they make the connection slower. Dishwashers, fridges, microwaves, and other devices that have electric connections emit radiation waves. The waves are very effective because they significantly interfere with the signal quality.

It will have a low potential because they tend to make the connection quite unreliable. For example, electrical interferences make the connection very poor and signal to channel poor and unreliable.


Another method of preventing Wi-Fi from getting beyond a room is the choice of furniture. If you have a business house, you may have tons of tables, chairs, desks, shelves, and many others. If they have thick materials such as books, the connection will have a significant reduction of speed.

Placing the router at a strategic point and blocking some parts with furniture will make the connection lower. However, it will not penetrate hence making the speeds quite unreliable.


Water blocks the signal and absorbs it. It has many impurities that make it a conductor of electricity which is the principle behind managing the Wi-Fi signals. Unfortunately, it also reflects the signal making the quality quite unreliable.

Water bodies such as fish tanks, waterfalls, human beings, and others significantly lower the connection’s quality. Connection to the nearby devices lowers, making the connection speed unreliable.


Blocking Wi-Fi in a room is not as complicated as most people think. If you have the materials you need and choose a specific method, you will conveniently implement the various measures. However, speeds will significantly lower when traveling within the connected devices, making the quality not dependable.

There are many ways that can be used but if you want something simple and effective then here we have given some of the best methods using which you can block WiFi easily.

The problem is that you cannot turn off the Wi-Fi router or switch it on and off at will because of its location, plus you dont want to disconnect all the devices from their internet access.

There are simple ways to block Wi-Fi in a room so that no one can use the network there anymore. The options above are for blocking Wi-Fi in a room without turning off your router or affecting other devices connected through it.
