Today Wi-Fi is essential for our everyday life. But at the same time, wifi’s convenience can also bring risks and unwanted problems. Do you ever get annoyed when unwanted people connect to your Wi-Fi, making your internet slower? If that’s the case then doesn’t worry.  In today’s article, we will learn how to block Wi-Fi signals from the router. This will easily prevent unauthorized access. Let’s get started. 

Why Should You Block Your Wi-Fi Signals?

You are coming home after a long, exhausting day and you want a moment to relax. As you relax at home, you look forward to watching your favorite show or checking your emails. But, your internet slows down a lot. This makes simple online tasks very frustrating. 

If your neighbor is secretly using your Wifi, it will slow down your internet. This situation is very common nowadays. But, you can take steps to stop others from using your Wi-Fi and protect your online space.

How To Keep Your Wi-Fi Network Secure?

Before you try to stop your Wifi from working, make sure your wireless network is secure. If you create a strong Wi-Fi signal barrier, it prevents unauthorized users from using your network.

Many routers come with default settings for the network name and password. These basic keys can be easily guessed or obtained by anyone nearby. 

Default logins can put your network at risk. Tech-savvy people might misuse it easily. You should replace default settings with a complex password to secure your Wifi network. You can also create a unique digital key for better security against decryption.

You should create a password that uses more mixed-up and varied characters. Use a mix of capital and small letters, numbers, and symbols. Avoid common patterns or personal info. This complex code will prevent hackers from trying to break into your network.

How To Adjust Your Router Settings?

To increase the layer of security, you can also add encryption. It jumbles the data on your Wifi. So only those with the decryption key and your password can read it. 

You can check your router settings for WPA2 encryption. It is one of the best choices for securing your home Wifi network.

You can also use a feature called WPS (Wi-Fi Protected Setup) on your router. It is convenient for quick connections, but it has some security vulnerabilities. You should keep your WPS disabled. This is generally recommended for an extra layer of protection.

How To Block Wi-Fi Signals From Router?

Now that your Wifi network is secure, let’s explore ways to control the signal. Here are three main methods:

1. Control Router Settings

Your router is the command center for your Wifi network. Changing your router’s settings opens up many ways to control who can connect. Let’s see how: 

  1. Every router has a special web address called an IP address. This address helps you access and change the router’s settings. Flip your router to the back. Look for a sticker with the IP address and login details. If you can’t find it, a quick web search for your router model will usually do the trick.
  2. Navigating the Settings is easy. You should log in to your router. Then find the “Wireless” or “Security” menus. Different brands may have different layouts, but most routers work similarly.
  3. Every device with Wifi capability has a unique identifier called a MAC address. MAC Address Filtering lets you make a list of approved devices. You can block others from accessing your network by controlling MAC addresses. This allows only specific devices to connect.
  4. When friends visit, you can give them their own Wi-Fi. They won’t change your main Wi-Fi or see your personal stuff. A guest network provides a separate, temporary Wifi connection with limited access. Your guests can use the internet without risking your main network’s security.

Optional Hack: Adjusting Wifi Channel

Your neighborhood might be a crowded space for Wifi signals. For example, multiple radios are trying to broadcast on the same frequency. You can stop this by changing your Wifi channel. This will help you to reduce interference and strengthen your signal at home.

You can also adjust the power of your wifi signal to make it stronger or weaker. But please be careful! A stronger signal can pass through walls and reach unintended places. So you should use this with caution!

2. Block Wi-Fi Signals with Barriers

Certain materials, such as metal and concrete, can weaken Wifi signals. This doesn’t mean you need to build a cage around your router. You can simply place metal or concrete objects strategically. This can weaken Wifi signals in certain spots.

But please remember that this method is not very precise. A metal filing cabinet may weaken the signal in your home office. But it could also unintentionally affect the signal in adjacent rooms.

3. Schedule Your Wi-Fi

Some routers come with parental controls. This allows you to set time limits for Wifi access. You could make a plan to stop the Wi-Fi at bedtime.

Frequently Asked Questions (FAQs)

1. Can I completely block my Wifi signal from everyone?

Unfortunately, no. Wifi signals are radio waves. They can travel through walls and reach some distance. The methods we talked about can reduce how far your wifi signal reaches and make it harder to connect.

2. What if I forget my Wifi password?

Most routers have a reset button that allows you to restore factory settings. This will reset your password to the default one on the router, usually found on a sticker on the back. Once you are connected again, be sure to switch the default password to a stronger one!

Is it safe to block my Wifi signal?

Yes, in most cases, blocking your Wifi signal is perfectly safe. It is your network, and you have the right to control who can access it. But at the same time, it would be wise to check the local rules in your area. You can also ask the internet provider to make sure you are not breaking any rules.

What if none of these methods work?

If you are having trouble with your Wi-Fi, it could be a good idea to get a new router. Newer routers usually have better security and signal control.

5. Are there any legal concerns about blocking Wifi signals?

In most cases, no. But it is always best to be on the safe side. Local regulations might have specific rules about intentionally interfering with radio signals. You can do a quick web search or call your local authority to clear up any doubts.


By now, you have tried different ways to block your Wi-Fi signal. You have adjusted router settings and placed furniture strategically. Remember, the best approach often involves a combination of these techniques. Having a safe network with a strong password gives you primary protection. 

You can also use wired connections for stable and secure connections. This is suitable for devices like desktop computers or gaming consoles. Your aim should be to find a good balance between keeping things safe and easy to use.

So you can easily block wifi signals from what you have learned in this article. It will help you make a safe space for you and your devices.
