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

In this post I will teach you how you can block intruders on your Wi-Fi network, once detected who they are. No one else will steal your internet. ENTERS!

 

WE START:

It's actually very annoying to know that someone is taking over our network, right? When he or she knows that you pay for your network, in addition to that, it is probably encouraging your connection, TO YOUR OWN NETWORK, it is actually very tedious, it gives a lot of anger, I know, BUT NOT MORE, in this post your suffering ends.

In a previous post, I posted how you can detect intruders on your Wi-Fi network, where it explained in detail how to do the first step: detect them. Also, I provided a program that in this same tutorial we are going to use it 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.

Okay, with that being said, 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 on "Search" (located in the upper left part of the program), and the program will begin to scan all the IP addresses that are connected to your Wi-Fi network.

3) When done, minimize that window. Now we are going to proceed to prepare the blocking of the intruder, and to do that, we will have to access the configuration of our router.

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

blank

The IP address of each router is unique and different, so the one you see in the image will not be the same as yours. When you have found it, we can continue:

5) Go back to your computer, open your preferred web browser and paste the address of the «Login» section of your router and enter.

6) It will show you a site to log in. Put in the user section the "Username" on the label of your router, and as password, the "Password" on the label of your router.

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, since the configuration panel in each Router is different, but the options that we will see are almost always with the same name. Now we are going to copy the MAC address of the intruder. Minimize the browser.

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

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 in that section it tells us the information of our network, such as name , key, etc). Once that's cleared up, go to an option called "Access Control" or "Access Control."

10) Locate the section "Mac Filtering" or "Mac restrict Mode"; "Mac Restriction Mode". Pull down their menu and click on "Deny."

11) Paste the intruder's Mac address in a text section that appears there, and click on the button to apply the changes, which is usually "Apply" or "Apply".

12) READY, OUT INTRUDERS!
