How to know if someone is connected to your Wi-Fi network without permission

Having ones own Wi-Fi network was not very common in homes a few years ago, although now we could not live without it. Given its importance, you should take care of it so that it works as well as possible, following those tips that Google gave you to improve your Wi-Fi. If your internet connection is still not working as it should, it’s time to ask yourself that maybe someone is using your network without permission.

How to know if someone is connected to your Wi-Fi network without permission, and how to avoid it

It is possible that a neighbor has taken the password for your Wi-Fi and is enjoying the advantages of it without your knowing it. But this has a solution, since you can easily discover which intruders are connected to your network and remove them from it . We explain how to do it and what steps you should take to prevent them from re-appropriating your connection.

How to dis-connect your Wi-Fi users from your network

Not only should you protect yourself when browsing public Wi-Fi networks you must also protect yourself when using your private connection at home. One of the possible reasons why your Wi-Fi network is not performing properly is because devices that should not be connected to it, that is, there are intruders in the connection.

To find out if someone is connected to your Wi-Fi network without your permission, you must first see what devices are connected to it. When you have the complete list, you must analyze each device until you know if they are yours or correspond to other users who have taken the password for your router.

To do this, you must first know what the connected devices are. In the Play Store you can find a multitude of free applications for your Android mobile or tablet, although we recommend 3 of them: Fing, WiFiman and Who’s on my Wi-Fi ?. Here below we leave the links for you to download.

These applications, and the rest that you can find in the store with the same functions, are simply network scanners that reveal which devices are connected to your Wi-Fi . By knowing this information, you will know if it is your mobile, tablet computer and other technological devices, or there are some other intruders.

To differentiate your devices from those that are connected without your permission, you must look at their names, their IP addresses or MAC addresses . These are identifying data of each device, and therefore they will help you detect which ones should not be there.

In addition to these applications, you can also see what devices are connected to your Wi-Fi network if you go into the router settings from your Android . One of the ways to do this is to put the address “192.168.1.1” in any web browser . Afterwards, you will have to enter the username and password, which are usually “admin” both (a major weakness).

Access to your router settings may vary depending on the phone operator. For example, in the case of Vodafone, the user is “vodafone” and the password appears on the router itself. Once inside the configuration, you will be able to see which devices are connected to the Wi-Fi network, detecting those that do so without permission. Once recognized, it is time to eject them from your network so that it works again normally.

How to kick intruders from your Wi-Fi and prevent them from re-entering

Let’s go to the important thing, how can you kick out those intruders who have hijacked your Wi-Fi network? There are several methods for this, but the easiest is to change the router password so that only you can access the connection. To do this, you will have to enter the router settings and modify the password you had so far. Of course, you should choose a complicated alphanumeric code, and not limit yourself to the dangerous 12345.

Another method is to use the NetCut application, whose installation file you can download for free on your Android or computer. After installing the application or program, you must analyze the network to find all the devices that are connected and eject those that are not yours by selecting them and clicking on the “Cut Off” option.

After you’ve kicked out the intruders, it’s time to beef up your Wi-Fi network to prevent them from reentering. After you have configured a highly difficult password, you must deactivate the WPS function of the router, which allows access to the connection with a PIN code of only 8 digits. For hackers, it is much easier to discover this code and access the router, so it is best to disable it.

In addition to expelling the intruder, it is also recommended that you filter your MAC address in the router settings so that the same device cannot reconnect in the future, even if you know the password. Speaking of the latter, you can change it with some frequency to ensure that only you know it.

Finally, it is a good idea to turn off the router whenever you know you will not be using it, especially if it is going to be for a considerably long period. In this way, you will be sure that nobody takes advantage of your Wi-Fi network without your permission to connect to the Internet.
