How to Block Wifi Signal in a Room

Looking for how to block WiFi signal in a room? You are in the right place because this article will help you learn all the information on how to do that. 

WiFi is very sensitive, and its waves cannot penetrate metal. But instead, they will be bounced or reflected off the metal and unable to reach the area. 

So, there are many ways to block your WiFi signal in a room, either permanently or temporarily. Continue reading to learn all of them.

How to Block Wifi Signal in a Room

If you want to block out wifi signal in a room, you should line the walls with aluminum foil or mylar blankets with the aluminum facing outward. 

There is also wallpaper, like Meta paper, that blocks out WiFi signals, or you can just paint the walls with conductive paint. However, a step-by-step guide and a third-party tools method for better understanding is here.

Step 1

The first thing you should consider is where you position your wireless router.

Step 2

You should create an unfolded and flat piece and put it on some work surface or your table where ample space exists. 

Step 3

You can apply craft glue or cardboard to the inner surface of the cardboard. If you want to cover the entire inside of the box, you should take many strips of aluminum foil. If you want to avoid a sloppy mess, the initial adhesive layer should be roughly the thickness of a strip of aluminum foil.

Step 4

You can apply a strip of aluminum foil to the carton’s glued part and ensure it is long enough to cover the width of the carton. You should fold the edges of the aluminum foil around the carton’s edges if it is longer than needed. 

Step 5

You can repeat the previous steps until everything is covered with aluminum foil, and when the glue dries, you can continue using your WiFi. Remember to place it between your WiFi router and the direction you want to be blocked. 

Third-party tools

If you want a more comprehensive solution or a solution with more options, one method of blocking unwanted devices is through a third-party application.

Some third-party network tools give you more options than your router when controlling your WiFi’s user allowances. For example, some third-party applications can do the following:

  • Easier viewing of a list of all of your users on your network
  • Block unrecognized devices even before joining your network
  • Send notifications when a new device is added to or on your network.
  • Troubleshooting, speed tests, and other diagnostics all available in real-time
  • Recognition of IP addresses, model, vendor, MAC address, and manufacturer
  • Network security alerts to both your phone and your email.

Using a third-party tool might make your job a lot easier when it comes to ensuring the safety of your network. This helps you avoid the risk of unknown devices getting onto your network without knowing their intentions.

Side Effects of Signals

Nowadays, many people are affected by internet use. Still, we all know that WiFi signals have many side effects and emit various harmful radiations that are very dangerous and may damage the human body, including:

  • Radio waves
  • Electromagnetic radiations
  • Rays of dangerous wavelengths
  • Infrared radiation

All people who are conscious of the risk of all these radiations should be cautious and take particular measures to save themselves. 

What Is Blocking Your WiFi Signal?

Every time building elements such as steel and concrete or tanks and electronics may obstruct and interfere with WiFi signals, which may cause coverage issues in a home.

However, one of the main reasons for using newer devices that support the 5 GHz frequency band might be the signals on this band that have a shorter range and are less likely to generate or solve network interference than older devices that support the 2.4 GHz, frequency band. 

One of the main things that might be blocking the path includes your Bluetooth connection, neighbor’s network connection, individual wireless networks from your home, microwave oven, thick timber walls, Walkie-Talkies, baby monitors, floor, or metal heating. 

Blocklisting by device name

One of the main ways to keep a device off your WiFi is through the direct use of your router. Many WiFi routers give the option to block unrecognized devices simply, usually through a single button.

In general, you need to seek out the “device management” section – or your router’s equivalent and then you should be able to find a list of connected devices.

You will need to find the device listed along with your own devices and block the user. In general, it should be that simple, but every router is a little different, so it wouldn’t hurt to look up the guide or manual to your specific router if you’re struggling to find this option.

Blocklisting by device MAC address

This is a helpful method and is sometimes paired with other methods listed below. It is as simple as signing into your wireless router and adding your wireless MAC address, which is unique to your device and makes it difficult for others to clone or spoof it.

This is primarily one of the most straightforward ways, but it may take a time and is one where when you change your computer, phone, or another device, you will have to remember to sign in and add the new device to this list, or they will not be able to get online.

Conclusion

One of the best ways to block unwanted users is to learn how precisely you can filter out devices from having access to your wireless network. 

You should take some time to learn the admin console for your wireless router and make sure to change the default username if they allow, and it will be better if you constantly change the password. Once you do this, you will be more secure by default. 

However, after reading this article on how to block WiFi signal in a room, we hope it will help you learn the best methods to do it properly and effectively and make it much easier to do it yourself.
