How to Block WiFi Signal From Neighbors

If you have been encountering poor WiFi signals or sudden interruptions in the connection and have checked everything but found no problem, you have come to the right place. 

One of the biggest reasons for slower WiFi connection and an overall WiFi signal disruption is the mixing of the WiFi networks around your home. 

So, in this article, you can read how to block WiFi signal from neighbors. With this information in hand, the next time your WiFi network starts underperforming, you will know exactly what to do. Let’s begin!

How to Block WiFi Signal From Neighbors

If you live in an apartment building or a neighborhood with many households, it is no wonder that the WiFi signals start mixing, resulting in poor WiFi connection. If you are sure this is the case and the reason for your slow WiFi signal, worry not. 

With my super useful and efficient tips on how to block WiFi signal from neighbors, you will be able to retrieve the speed and quality of the WiFi network in no time.

All you need to do is carefully follow the instructions I share and finally start enjoying uninterrupted and super-fast internet.

Change the frequency of your WiFi

The first and foremost method you can try to block WiFi signals from neighbors is to change the frequency of your WiFi. This method is usually the most effective; most of the time, people do not need to try other fixes or solutions.

Before I share how to do this, I briefly want to mention that, as you already might know, WiFi services can come in two different frequencies: 2.4 GHz and 5 GHz. 

The first type of WiFi frequency, the 2.4 GHz, is characterized by longer-range signals but significantly slower. On the other hand, 5 GHz WiFi is characterized by shorter-range signals but much faster.

With this information in mind, you need to know that the 2.4 GHz WiFi is usually the one most impacted by other signals as its longer-range signals can travel quite far away from your home. This results in disruptions in the overall WiFi signal. 

So, that being said, if you are still connected to the 2.4 GHz WiFi frequency, you might want to consider changing to a 5 GHz WiFi frequency by using a dual-band router.

How to change the frequency from 2.4 GHz to 5 GHz

  1. First, you must open your modem’s website by entering the modem’s IP address (you can find it on the modem’s label or in the modem’s manual).
  2. After you open the admin website of your router, enter the ‘username’ and ‘password’ provided by your internet provider service.
  3. Once you enter the website, open the ‘Wireless Setup’ icon, and then from the option on the left, switch the settings from 2.4 GHz to 5 GHz.
  4. After this, open the ‘Radio Setup’ settings and select ‘Control Channel’, ‘Wireless Channel Width’, ‘Wireless Power Level’, ‘Mode (802.11)’, and finally, click ‘Apply’.

Try sending blocking signals to jam the WiFi of your neighbor

Another way how to block WiFi signal from neighbors is to send blocking signals to jam your neighbor’s WiFi. Remember that this is considered illegal in some countries, so please do research before proceeding with this method.

To send blocking signals, you can try using various applications or services or ask an acquaintance with excellent knowledge of technical WiFi.

Reduce the number of connected devices

The next thing you can try to block other WiFi signals from intertwining with yours is to reduce the number of connected devices

As you already know, the more devices you have connected to a single WiFi network, the more interruptions and problems of that type you might encounter.

Therefore, you can try eliminating and disconnecting some devices you do not necessarily use very often and only connect them again when you use and need them. 

This way, the WiFi network will not get overloaded, and as a result, you will be able to enjoy fast and uninterrupted internet.

Try installing a territorial setup

You can always try installing a territorial setup if you want complete control over your WiFi network signal. 

By doing this, you can prevent unwanted disruptions in your WiFi signal and even block the WiFi signals from your neighbors.

Although this mesh WiFi would require using an access point and a sign-up mobile application and might seem a little complicated, at least you will be sure there will be no more WiFi interruptions.

Change the position of the router in your home

Another incredibly helpful way to block the WiFi signal from neighbors is to change the router’s position in your home. 

If your router is too close to the wall you share with your neighbors, it is no wonder that both signals mix and you experience WiFi signal disruptions.

To fix this, you can try moving your WiFi router as far away from your neighbors as possible so that the chances for WiFi signal mixing are low to non-existent. 

You can also talk with your neighbors and reach a mutual agreement about where to put the WiFi routers in your homes so that there is enough distance between them.

Try and change the frequency of the channel

When you and your neighbors are using the same or similar WiFi frequencies of the channels, it would be even weird if you do not expect any WiFi signal disturbances. 

The first thing you can do to fix this particular problem is to use an app or directly ask the neighbors which frequency of the channel they use so that you can switch to another one and avoid WiFi signal disruptions. 

You can choose between frequencies depending on the type of WiFi you use, 2.4 GHz or 5 GHz.

After ensuring which frequency you want to switch to, you can do that by following these instructions:

  1. Open the admin website of your router by entering the router’s IP address in the search bar.
  2. Sign in using the username and password provided by your internet service provider.
  3. Click on the ‘Wireless Settings’ option and choose ‘Channels’.
  4. Under this option, you can select the preferred frequency.
