How to block intruders on my Wi-Fi network

August 18, 2017
Block intruders from our Wi-Fi network.

In this post I will show you how you can block intruders on your Wi-Fi networkonce they've detected who they are. No one else will steal your internet. ENTER!



It's actually very annoying to know that someone is taking over our network, isn't it? When he or she knows that you are paying for your network, besides, it is probably encouraging you your connection, YOUR OWN NETWORK, it is actually very tedious, it makes you very angry, I know, BUT NO MORE, in this post your suffering ends.

In a previous post, I posted how you can detect intruders in your Wi-Fi network, where I explained in detail how to do the first step: detect them. Also, I provided a program that in this same tutorial we're going to use again, so if you don't know how to detect them or you don't have the program, go to that tutorial and learn how/download the program.

Well, having said that, let's get started!

How do I block intruders on my Wi-Fi network?

1) Open the Wi-Fi Guard (program you downloaded from my previous tutorial)

2) Click "Search" (located in the upper left of the program), and the program will start scanning all IP addresses that are connected to your Wi-Fi network.

3) When you're done, minimize that window. Now let's proceed to prepare the intruder lock, and to do that, we'll have to access our router's configuration.

4) To do this, go to your router and turn it over, look for a section like this (it's where the access to your router is):


The IP address of each router is unique and different, so the one you see in the picture will not be the same as yours. When you've found it, we can move on:

5) Go back to your computer, open your favorite web browser and paste the address in the "Login" section of your router and log in.

6) It will show you a place to log in. Place the "Username" from your router's label in the user section, and the "Password" from your router's label as your password.

7) When you log in, you will be redirected to the main panel of your router. At this point you should read each option well, as the configuration panel on each Router is different, but the options we will see are almost always with the same name. Now let's copy the intruder's MAC address. Minimize the browser.

8) Return to WiFi Guard and click on the "View" menu (located at the top of the window), then display the "MAC Address Format" submenu and click on the second option (AA:BB:DD:EE:FF). You will see that the Mac address of all devices has been changed from "-" to ":". Right-click on the intruder's device, then display the "Copy" menu, and then click on the "MAC Address" sub-menu.

9) Go back to the configuration panel of your router, and go to the section called "Wireless" (as I mentioned, your router may have a different name, the important thing is to see if it tells us the information of our network, such as name, password, etc). Once that is clear, go to an option called "Access Control" or "Access Control".

10) Locate the "Mac Filtering" or "Mac restrict Mode" section. Expand its menu and click on "Deny".

11) Paste the intruder's Mac address into a text box that appears there, and click the button that applies the changes, which is usually "Apply".
