A recurring problem that exists in wireless connections is the entry of intruders or people who are not authorized to the WiFi network , in this way we have serious inconveniences regarding connection speed, as well as jeopardizes our security.
There are many ways to expel these unwanted visits, some of them are directly related to the privacy settings of our router. If we don’t want to have problems, we will have to follow the steps that we will mention in the following paragraphs to have a perfect shield of the router .
So that you know a little more deeply about WiFi theft, we have written this report so that you can configure your router and thus strengthen it against foreign income. We also bring the best applications related to this topic that will serve you incredibly.

What are the main problems that cause you to steal the Internet over WiFi ?
When we think that sharing the Internet signal with unauthorized people is simply an act of our selfishness, we are wrong. Because, in addition to dividing bandwidth into more devices, we will also have other much larger inconveniences.
Next we will show what are the main problems when strangers enter the WiFi network without our authorization:
Speed loss
If we have a router with 2.4 GHz frequency that has 13 channels, these are saturated more by having a greater number of devices connected in the same network, so it is necessary “clean that highway” of the Internet so that we can transit more quickly and safely.
Access to our privacy
As with almost all networks that are not configured, the devices that are part of it can access each other. In this way , an intruder can enter our private data in a very simple way , thus generating a very high risk in our privacy.
Change in revenue data
If we have not been able to block the entry of an unwanted person, they can access the configuration of our router and change, among other things, the SSID and password , generating that we do not We can enter our WiFi network.
We can solve it by calling our Internet operator to manage the necessary changes.
Disclosure of our SSID
Another factor to consider when intruders enter is that, they can do absolutely nothing for us to realize, just share our password with other people, so the number of connected devices will be increasingly large .
In this way, the connection speed will decrease considerably. This will also put our security at risk.
Why shouldn’t you let anyone steal internet from your WiFi? Causes
The reasons why it is not convenient for us to steal WiFi are:
Login with our IP
When we browse the Internet, the IP address that identifies us is the one that our operator gives us, therefore, if you enter any intruder and carry out illegal activities, they will be registered with our address .
In this way, one of the most important causes in terms of legality is to have absolute control of access to our wireless network.
Document theft
When our WiFi network is illegally accessed they can access our devices and thus obtain all the documents that we have stored in them.
In addition, you can enter different passwords from banks or other sites that are really private and be able to lose money without us noticing.
Join our Web Cam
Another factor to keep in mind is that, strangers or unauthorized people entering our network can have access to the webcam of some of the devices so our privacy has a high risk of being violated.
Steps to detect thieves who access your WiFi without your permission
When we need to detect intruders who access our WiFi network, we will have to follow this guide that we teach below:
From the router
If we want to detect who are connected to our router we follow this guide:
- We open our browser.
- In the address bar we type distinct168.1.1†.
- We type the username and address password.
- In this way we have entered our router. Your software will show us a control panel with different alternatives.
- We choose accounConfiguration†.
- We look for “Advanced settings” .
- Select “Device information” .
- We will see all the devices that are currently connected. with your MAC address IP number.
Another alternative we have is to disconnect all our devices that are authorized to enter the wireless network. This way our router should not have flashing lights, if so it means that there are intruders connected .
With an external program
There are different third-party applications that work very well for these tasks, in this case we will take “LanScan” , which is available for devices with MacOS operating system.
The steps are:
- Our blog we click on the application icon
- Next, select the green arrow (Scan) that is located in the upper left of our screen
- It will indicate the IP address, the MAC, the brand of the device and the DNS.
With a mobile application
We can use Net Scan to detect who is connected to WiFi, for this we will follow these instructions:
- We install the application from Google Play Store.
- Once in our mobile, we open it.
- We grant all the necessary permissions for its correct operation.
- We choose the network to which we want to analyze, for this we must enter it.
- Select beforeScanrd.
- We will see a report with SSID, IP, MAC address and device brand.

List of the best tools to identify who is stealing your WiFi from your network
In order to identify the people who are connected in our WiFi network, we can use some of these applications:
Wifi Inspector
This tool can provide us with reports of the devices that clandestinely connect to our wireless network. Some users think negatively of this app that it does not usually detect in a specific way the name or type of intruder device, since it only shows generic names. But is able to detect the MAC address and IP of the computer, mobile or tablet . It is currently available for Android .
WiFi Analyzer
It is a relatively new application where the name of this app tells us to know what your main job is, the deep analysis and scanning of devices in the WiFi network. Once the entire network is analyzed, it will show us the IP and MAC address of all the devices that are connected to our router at the time of the analysis.
It gives us the ability to allow adding devices that connect for the first time with our authorization to differentiate them from those that are fraudulently connected.
Fing
One of the most downloaded in app stores. This is due to the consideration that users have about the performance of their task to know who is stealing our WiFi or see who is connected to our network at a given time.
Thanks to the interface of this application it makes the operation very simple when it is already installed on iPhone or Android , for this we will give the permissions that are necessary so that you can scan the network WiFi.
It gives us a list of all the devices that are connected to the network with MAC address, name and IP, as well as showing us a connection history with its duration in each one.
Thanks to the fact that the application is not complex, it provides us with a speed test that will allow us to check the speed of our router and thus have an indication of why the Internet connection works so slowly. Available for Android and iOS.
Who is in my WiFi
Available for mobile phones with Android operating system. It is an application very similar to the one we saw earlier, since it is oriented to see who is connected to our wireless network. This is one of the simplest apps that exist .
Its development allows us that once we access it and grant it the necessary access to make it work, it will start scanning all kinds of devices that are connected in our wireless network.
When the scan is finished, it will show us a list of all the devices that are in WiFi , which will be classified by their names, MAC address and IP address.
WiFi Monitor
Another relatively new application, share with Fing as one of the most complete we found , in addition to being able to measure the speed of upload and download thanks to its network scanner and deliver a graphical report of network channel saturation.
When the scan is finished we will show the address of the connected device and its name. Available for Android mobile devices and is recommended for tablets.
GlassWire
When we need to know through our computer what devices are connected, we can use this tool. With it we will be able to analyze the use of bandwidth, the connection history of each connected device and the data that you are using at the time of analysis, so is highly recommended to protect our privacy .
If we need a firmware, this app can give us that option, which offers us protection against intruders and any device that we indicate as such. In addition, it gives us the possibility to see the report with extraordinary graphics that will show us the status of the network
Also, you can notify us immediately if someone connects to our WiFi. Available for Windows.
