How To Block WiFi Signal From Neighbors | 6 Easy At-Home Hacks

Are you wondering, how to block WiFi signal from neighbors? There could be many reasons why your internet is slow and the problem could stem from either an issue at your ISPs end or there could be a problem with your neighbor’s WiFi.

When your neighbor’s WiFi signal is strong, your WiFi signal will be disrupted. When there is a lot of signal interference, your WiFi signal will be weaker and results may be delayed.

This situation can be extremely infuriating and aggravating for those who work from home or take online classes.

You don’t have to argue with your neighbor about this anymore because you can easily block your neighbor’s WiFi signal. So, to your rescue, we have this post on how to block WiFi signals from neighbors.

How To Block WiFi Signal From Neighbors

How Can I Tell If My Neighbor’s Wi-Fi Signal Is Powerful Enough To Cause Interference?

WiFi signal issues can be multifaceted. Before assuming that your neighbor’s WiFi interfered with yours, verify with your service provider or try refreshing your router.

If everything appears to be in order except for your neighbor’s WiFi regularly popping into your range, you should consider it a potential disruptor.

While you and your neighbor may have distinct service providers, two competing signals will cause interference, especially if they are in close proximity and overlap.

  • By analyzing its radio frequency spectrum when it travels within your range, you can determine the strength of your neighbor’s Internet connection.
  • The name of a WiFi network may indicate whether it operates at 2.4GHz (gigahertz) or 5GHz.
  • You can also examine the WiFi signal bar and compare it to the signal of your personal network.

Signal interference is possible if your devices operate at the slower 2.4GHz frequency while your neighbor operates at the faster 5GHz band.

Solutions For Blocking Wi-Fi Signal From Neighbors

Adding the network name to your device’s block list just obscures the network name and has no effect on the signal. Here are three practical ways to block your neighbor’s WiFi signal:

Change your router’s placement at home

How To Block WiFi Signal From Neighbors

Moving your router away from your neighbor’s router is the simplest technique to get a good signal. Relocate it away from the sidewalls and into a more central area in the house.

It will be easier to choose a location if you know where your neighbor’s WiFi is located. Otherwise, you’ll have to try one location at a time and see if anything changes.

This approach of moving the router works only in non-congested areas. This strategy may or may not work if you live in a development with densely packed houses or an apartment with only walls as dividers between you and your neighbor. You do, however, have alternative possibilities.

Shift to another frequency

How To Block WiFi Signal From Neighbors

There are two WiFi frequencies that are regularly utilized. The 2.4GHz frequency range is longer but slower, whereas the 5GHz frequency range is shorter but faster. For three reasons, you should switch to the 5GHz band to avoid signal interference.

  • First, because the 5GHz frequency is less prevalent than the 2.4GHz frequency, there is a greater likelihood of less competition in any particular location.
  • Second, it has a shorter range. Even though you and your neighbor share the same 5GHz band, you can relocate your router around the home to get a stronger signal.
  • Third, it has a greater number of channels than the 2.4GHz range. If numerous people are utilizing the same frequency, you can change to a channel with fewer users.

Get a Territorial setup

You can utilize a wireless mesh system to ensure continuous signal and internet connectivity. You are not affected by disturbed WiFi signals caused by your neighbor’s WiFi, but your neighbors may be affected by your Territorial configuration.

Change your frequency’s channel

Each WiFi frequency has its own set of channels. The 2.4GHz frequency contains 11 channels, while the 5GHz band has 23. (or sometimes higher). Due to router constraints, shifting frequency is not always possible.

Before you invest money in a new router, try switching to a different channel. Consider this strategy to be equivalent to changing radio stations.

  • If a warning message opens, simply click ‘Advanced’ followed by ‘Proceed.’ Your login and password will be required.
  • Once logged in, navigate to ‘Wireless Settings’ and select the ‘Channels’ drop-down menu.
  • Change the channel from ‘Auto’ to your preferred channel, then save your changes.

You may always check the signal speed in your area from time to time. Use to determine the speed based on your neighbor’s WiFi’s ON/OFF status.

Reduce the number of connected devices
