How To Block WiFi Signal In A Room?

There are multiple situations in which a person needs to block wifi signal for a particular room, but how it is possible to block the wifi signal? Well, the below-listed methods are useful through which you can block or reduce the wifi signal for your desired space.

Here are a few simple and powerful methods which you can try:

Use A WiFi Signal Blocker:

These are one of the best and most outstanding devices that are uniquely designed to block WiFi signals for any space. The working of wifi signal blockers is amazing because it will create a wall of interference through which you can’t get a wifi signal in a specific room.

However, keep in mind that these devices are particularly used for multiple security reasons, especially in military bases or government buildings.

Use Metal Objects:

You can also use various metal objects such as metal appliances, and metal file cabinets, these are the particular metal devices that help you to block wifi signals. However, all you have to do is simply place these metal objects between the room where you want to block wifi signal and the wifi router.

In this way, you can easily block or reduce the wifi signal frequency in no time. But keep in mind that you can’t fully block or reduce wifi signals with this method, as it only reduces the strength of wifi signals.

Use A Faraday Cage:

It is another best method through which you can definitely block wifi signal to your particular room. However, keep in mind that a faraday cage is an overall metallic enclosure that is able to completely blocks electromagnetic fields.

You can also create a DIY faraday cage by yourself by simply lining a room with metal foil or just with metal mesh. Moreover, if you can’t create a faraday cage by yourself, then there are various built-in Faraday cages that you can purchase from any nearest store.


Keep in mind that these methods may not fully block the wifi signal in a room, but they are worth trying once. However, it is better to choose methods that are better completely in your situation. This is just to consider first the overall potential risks of doing so.

Some Other Best Ways To Reduce The WiFi Signal In A Particular Room

The below listed are the additional methods that also help to reduce or eliminate the strength of wifi signal, which include:

Use Thick Walls:

While using thick walls or use multiple walls can effectively reduce the wifi signal. It is just because wifi signals are not transferred completely through multiple walls. Additionally, it is one of the effortless and best methods through which you can eliminate the wifi signals for a specific room.

Moreover, if double walls can’t help in reducing the wifi signal then you may need to add more thick walls or materials and see if this helps to block the signal.

Use A Wifi Repeaters:

Keep in mind that wifi repeaters are also known as the wifi extenders which are especially used to completely amplify the wifi signal in no time. These wifi repeater devices can helpful for certain areas of your office or home, where you want to block the wifi signal.

So, no doubt using these devices will be surely helpful for you to reduce the overall strength of the wifi signal in a specific room or space.

Moreover, all you have to do is simply set the repeater only to a lower signal strength option or also can place it farther away from your desired room in which you want to block the signal.

Use A Wireless Access Point:

It is the last method that works great to reduce the strength of the wifi signal. A wireless access point is a unique device that especially allows you to only create a separate wireless network, especially in your office or home.

Moreover, after that, it will create a gap, especially in the wireless coverage that effectively blocks the wifi signal in your desired room.

Final Thoughts

There are several methods that are really helpful to block or reduce the wifi signal strength in no time, but the above-listed methods are the best and tested methods to block the wifi signal in a room.

These options include using a faraday cage, a wifi signal blocker, metal objects, thick walls, a wireless access point (WAP), and a wifi jammer.

Moreover, it is important for you to know that these methods may not completely reduce or block the wifi signal, and also some of the methods are feasible which only depends on your situation.

It is better to first study your country’s local laws before using a wifi jammer because it is illegal in multiple countries.
