Most people use a WiFi connection at home., which they access from their phones or from their computers. There are times when we suspect that someone is accessing our WiFi network without permission. Faced with this type of suspicion, many seek how to know if they steal my WiFi and then block them, those people who access the network without permission.
We are going to talk about this below. we are going to show you how to know if my wifi is stolen, as well as how to block them. In this way, those people who are accessing your WiFi network without permission will not be able to enter again. There are several methods to know this, so surely there is a way that suits you.
Signs that my WiFi is being stolen
Of course, If someone suspects that they are stealing WiFi, it is because there is some indication. You have noticed that something is different with your connection and it is possible that other people are entering your network without permission. The normal thing is that we have noticed that there are some changes in this connection, in its operation, which makes us think that someone has entered without permission. This is something that we can normally notice through these types of changes or behaviors.
- The Internet connection suddenly becomes very slow.
- The Internet connection slows down at very specific moments or times of the day (always at the same time, for example).
- This connection drops most often.
The normal thing is that this happens, that the connection suddenly works worse, without there being a clear reason for it (there is no fault or works in your area). So if this happens, it is normal to think that someone is using our WiFi without permission. So we need to check this out.
How to know if my WiFi is stolen
If we want to check who is connected to our WiFi network, the best and easiest way to do this is by accessing the router directly through the web address on the bottom of the device. Next to that address, we will find the username and password to access the router, which is different from the password for its WiFi signal. In this case we can see who is connected to that network at that time.
That specific address starts with 192.168.xx. We are only going to have to enter this in the browser on our device, to access that menu with router options. Here you can see that we have a series of options, some of them possibly too complex for many users, but that will allow us to see the devices that are connected to our network at that moment. So they give us valuable information.
Since we can see if there are more devices than should be connected, for example. If in your house there are only two or three devices connected to the WiFi network, but in the list you see that there are more or you do not recognize their names, then this already tells you that there are people connected to your network without permission. Next to the name of each device we will see that there is a button, which is the one that will allow us to expel this person from the network.
So we will be able to expel those unknown devices that are connected to the network without permission. In addition to expelling them from our WiFi network, it also allows us to block them. So these devices will no longer be able to enter our network, which is exactly what we wanted in this case.
Android applications
Also from Android you can control this. Many are looking for how to know if they steal my WiFi and block them directly from the phone, something that is possible, luckily. Since there are applications available in the Play Store that allow us to check if there are people connected to our WiFi network illegally, without our permission. This way we will be able to subsequently expel these people from the network, in addition to blocking their future access.
Therefore, below we leave you with some of these apps we can use to know this. To be able to see who is using our WiFi network and the way in which we can expel them from it in a simple way. So we can do the entire process on our Android smartphone.
Network Analyzer
Networl Analyzer is one of the best applications in this field that we have available in the Play Store. This app will allow us to perform an analysis of our WiFi network. It will then allow us to see all the devices that are connected to our router, along with the IP and its Mac address. So in a very simple way we will be able to check if these are our devices, and see how many are in this list that are not ours, that use the network without permission at that time.
There are times when this app is not able to identify the device name, which in some cases will force us to try to find out what device it is, a task that can be more or less simple, depending on the device . Of course, if we have identified a specific device, we will be able to add a name, so that it will be identified at all times in the future. Thus, if it is a device that does not belong to our house and that we do not want to connect, we will be able to identify it and know it whenever there is an attempt.
This is an app that we can Download for free from the Play Store. The app has a free version with ads, as well as a paid version that gives us access to a series of additional functions. For this purpose that we are telling you about, its free version fully complies.
How to prevent my WiFi from being stolen
If we have already detected those devices connected to our network without permission and we have also expelled them, it is time to take action. We must prevent others from being able to connect to this WiFi network without our permission. For this reason, there are a series of things that we can do in this regard, which will prevent others from entering this network without our knowledge or without our having given them permission, for example.
WiFi password
Something of great importance in this case is that Let's go change the password of our WiFi network. If others have been able to connect, it is because they have found out that network access key, so we must take measures in this regard, to prevent this from happening again. So a new key becomes a necessary thing in these cases. In addition, it must be a secure key and one that is not easily guessed.
It is best to use some random key generator, so let's make sure it's something complex. Since there will be letters, numbers, varying between uppercase and lowercase, for example, as well as some symbol or character that is not usual. These types of keys are much more complicated to hack, so we will prevent others from being able to connect to our WiFi without our permission. It is a good protection in this sense.
Be careful who you share the key with
If you have people who come to visit or if you share the key with other people, it is important that you are going to be careful with those people to whom you give your WiFi key. You don't want anyone to have access that they shouldn't have, so it's good to limit the number of people who have access to your network. You avoid problems this way.
Use Mac connection
Another method that can work to prevent others from stealing or entering our WiFi without permission is this, the use of the Mac connection. Every device with an Internet connection on the market has a Mac address or connection. The Mac of the devices who connect to the internet is a single registration, a license plate that can only have a specific device. So it is something that identifies that device.
If you are tired of seeing how other people connect without your permission to your Wi-Fi network and use your Internet connection, despite the fact that you have changed your password regularly, then you have to take other measures. The best thing you're going to be able to do in this type of situation is to make the devices only connectable to the router through your Mac. It's something that all users can configure on their devices.
In this way, every time we want a device to connect to our Wi-Fi network, it is necessary to manually enter the Mac on the router via its login page. This way we have control over the devices that connect to our network at all times.
