Table of contents:

Parents have asked me, “Can you block a device from WiFi?” at least a hundred times already! Their reason nine out of ten times was they wanted to stop their kids from spending too much time on the Internet, and the other was they suspected their neighbours were using their WiFi! Do you have similar reasons? Whatever your reasons, in this article, I’m going to tell you all the different ways to how to block a device from WiFi. Besides, by the end of the article, I’ll offer you an alternative solution to protect your kids from wasting their time on useless apps and websites online. 

 

Keep the WiFi Password a Secret 

Any smart device can connect to a WiFi network as long as they’re within the range and have the network password. So, basically, you can block a device from WiFi by not giving users the password. You can set or change this password in your router’s settings (explained later in this article). 

 

Forget the WiFi Network 

What if your child’s phone, tablet, or computer is already connected to the home WiFi? Can you block their device from using your WiFi? In that case, you can forget the home WIFi network on their devices. Depending on the device and operating system your child uses, you need to use one of the instructions below: 

 

iOS 

  1. Open “Settings” and then “WiFi” 
  2. Select the WiFi network you want to forget by tapping the icon that looks like an “i” in a circle 
  3. Select “Forget This Network” 

 

Android 

  1. Open “Settings,” and navigate to “Wireless & Networks” (It may come under different titles in some phone models) 
  2. Tap and hold the network you wish to forget 
  3. Select “Forget Network” from the menu 

 

Windows 10 

  1. Click the “Network” icon in the right corner of the taskbar 
  2. Click “Network Settings” 
  3. Click “Manage WiFi Settings” 
  4. Select the network you wish to forget from the list under “Manage Known Networks” 
  5. Click “Forget” 

 

Windows 11 

  1. Click the “Network” icon in the right corner of the taskbar 
  2. Click the “Network Status Button” (top left) 
  3. Right-click the network you wish to forget 
  4. Click “Forget” 

 

macOS and OS X 

  1. Click “System Preferences” 
  2. Click “Network” 
  3. Click “WiFi” from the list of options on the left 
  4. Select “Advanced…” on the lower right 
  5. Select the network you wish to forget, then select the “-” (minus) button 

 

Change the WiFi Password 

Is your WiFi password too easy for your child to guess or memorise, or do you think they’ve already written it down? In that case, you can change the WiFi password. To do so, you need to access your router’s configurations. 

How to Change the WiFi Password 

To change the WiFi password, follow the steps below: 

  1. Open a web browser on your computer or phone (it doesn’t matter which browser) 
  2. Type your router’s IP address in the address bar. You can find the IP address on the back of the router. If you can’t find it there, you should be able to find it somewhere on the router’s package, manuals, or the manufacturer’s website. Usually, it is 192.168.1.1, 192.168.0.1, or 192.168.100.1 
  3. Enter your username and password to login into the router’s configurations. You can see them again on the back of the router. With most routers, it is “admin” and “admin”. However, you or the technician who has set the router up for you might have changed the password. In that case, enter the modified password. If you have forgotten the password, your only solution would be to reset the router. Nevertheless, resetting the router deletes all your router settings, meaning that you have to set it up anew 
  4. After successfully entering the router’s configurations, look for a tab that reads “Wireless, WLAN, or Wireless Security” 
  5. On the security settings, find the “WiFi Password” field 
  6. Enter the new password and save the changes. The changes will apply after a quick restart

Change/Hide Your WiFi SSID 

How to block certain devices from WiFi without users being notified that you’ve changed the password? For that matter, you can change the SSID, which stands for Service Set IDentifier (your WiFi network name, in simple words). 

After changing the SSID, users may think the router must be turned off. Once you change and hide the SSID, users must enter the WiFi name and password whenever they want to connect. To do so, follow the steps below: 

  1. Open the setting page of your router (explained in the previous heading) 
  2. Navigate to the WLAN setting 
  3. In the SSID name field, enter a new name for your WiFi network 
  4. When you see an option that reads “Enable SSID”, uncheck it and save the changes

MAC Address Filtering 

Changing the WiFi password or SSID means all devices connected to your WiFi router should reconnect. To avoid the hassle, you may want to try MAC address filtering. MAC stands for Media Access Control. It’s a 12-digit number unique to every device. By whitelisting or blacklisting a device’s MAC address in your router’s settings, you allow/disallow that device to use the WiFi. You can see this option under “Security” or “Advanced” settings on your router configuration page. 

To tell you the truth, when I was testing MAC address filtering to write this tutorial for you, I thought blocking a device from WiFi using this method was inefficient. The steps you need to take are complicated. Besides, a tech-savvy child can go around your settings. While there are other methods you can use to cut your child’s access to WiFi, there should be no reason for you to try MAC address filtering. However, I decided to include this method to give a comprehensive tutorial. 

If you already know the MAC address of the device you want to block, follow the steps below. Otherwise, read Lawrence Technological University’s article on how to find different devices’ MAC addresses and then come back to read the rest of the tutorial. 

  1. Use a web browser to load your router’s configurations (explained earlier in this article) 
  2. Go to the “Security” tab and select “WLAN MAC Filter Configuration” 
  3. Enter the MAC address of the device you want to blacklist or whitelist. Again, blacklisting means that the device with the defined MAC address can’t use the WiFi network, and whitelisting means the opposite. 

 

 

WiFi Blocking App 

An easy and practical alternative to MAC address filtering is WiFi-blocking apps. You can use these apps to see what devices are connected to your home WiFi, disable unwanted network access, and manage your network password. 

If you’re interested in blocking a device from WiFi at home using this method, WiFi Blocker from Test-Alpha Ltd is a perfect choice. With WiFi Blocker, you can block as many devices as you wish from WiFi, manage the WiFi password, and see what devices are connected to the network. You can also group devices to control their access more easily. That means, for example, you can disconnect all of your child’s devices with a push of a button. 

While testing WiFi Blocker, I was thrilled to find out it comes with WiFi access schedules for each person using the network. That means you, as a parent, can set time intervals for your child to use WiFi on each day of the week. You only need to set the schedule once; everything else will be automatic.

Use Parental Control Apps to Keep Your Child off the WiFi 

The Internet can be, in fact, a beneficial tool for kids. Take a look at “16 Educational Apps and Sites for Elementary Schoolers in 2023 to see how valuable the online world can be. However, I don’t deny that kids are prone to spending a lot of time on useless apps and websites. Besides, some platforms are inappropriate for younger kids, causing safety and health risks. So, you’re totally right to want to keep your child away from these harmful sides of the Internet. But you don’t want to stop your child from benefiting from the good side of the Internet either, right? 

 

What’s Safes’s Solution? 

Instead of shutting off the Internet on your child, you can install parental control apps like Safes to protect them from harmful apps and websites. Using Safes, you can see what apps are installed on your child’s phone. You can then block the ones you find inappropriate for your child. You can do the same thing with the websites your child visits. Safes collects thousands of inappropriate websites and search keywords which you can block with a simple click. 

If your child’s screen time is a problem, you can set screen time limits for any app your child uses. After they go past their daily time limit, the apps will stop working. Moreover, using the Bedtime Mode, you can ensure your child can’t stay up after bedtime using the Internet.

Cyberbullying laws
Until the mid-2000s there were no specific laws considering cyberbullying activities. But legislators have considered increasing number of school violence, self-harm or suicides among teenagers. Some states preferred to leave this matter in the hand of school and there have been some restrictions towards cyberbullying in schools. In these cases, cyberbullying is often threated as a civil matter rather than a criminal one.
