A recurring problem that exists in wireless connections is the entry of intruders or people who are not authorized to In this way we have serious problems in terms of connection speed, as well as putting our security at risk.
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 shielding 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 strange access. We also bring the best applications related to this topic that will serve you incredibly.
What are the main problems that cause your Internet to be stolen over WiFi?
When we think that sharing the Internet signal with unauthorized people is simply an act of selfishness on our part, we are wrong. Because, in addition to dividing the bandwidth between more devices, we will also have other, much bigger inconveniences.
Next we will show what the main problems are when strangers enter the WiFi network without our authorization:
loss of speed
If we have a router with a 2.4 GHz frequency that has 13 channels, these become more saturated by having a greater number of devices connected to the same network, so it is necessary “clean up that highway” of the Internet so that we can travel more quickly and safely.
Access to our privacy
As in almost all networks that are not configured, the devices that are part of it can access each other. In this wayan intruder can enter our private data in a very simple waythus generating a very high risk in our privacy.
Change in income data
If we have not been able to block the entry of an unwanted person, they will be able to access the configuration of our router and change, among other things, the SSID and passwordgenerating that we cannot 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 take into account when intruders enter is that they may do absolutely nothing for us to notice, only share our password with other people, so the number of connected devices will be larger and larger.
In this way, the connection speed will decrease considerably, as well as our security will be put at risk.
Why you shouldn’t let anyone steal internet from your WiFi? Causes
The reasons why it is not convenient for WiFi to be stolen are these:
Login with our IP
When we browse the Internet, the IP address that identifies us is the one given by our operator, therefore, If an intruder enters and carries 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.
Theft of documents
When our WiFi network is accessed illegally can access our devices and thus obtain all the documents that we have stored in them.
In addition, you can enter different passwords of banks or other sites that are really private and you can lose sums of money without us noticing.
Access to our Web Cam
Another factor that must be kept in mind is that strangers or unauthorized persons entering our network may have access to the webcam of some of the devices so our privacy has a high risk of being violated.
Steps to detect thieves accessing your WiFi without your permission
When we need to detect intruders accessing our WiFi network, we will have to follow this guide that we teach below:
from the router
If we want to detect who is connected to our router, we follow this guide:
- We open our browser.
- In the address bar we write “168.1.1”.
- We write the username and password.
- In this way we have entered our router. Its software will show us a control panel with different alternatives.
- we choose “Setting”.
- we seek “Advanced configuration”.
- we select “Device Information”.
- It will show us all the devices that are connected at that moment. with your IP number MAC address.
Another alternative that we have is to disconnect all our devices that are authorized to enter the wireless network. In this way our router should not have blinking 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, for this case we will take LanScanwhich is available for devices running the MacOS operating system.
The steps are:
- Our blog we click on the application icon
- Next, select the green arrow (Scan) which is located at the top 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 installed the application from the Google Play Store.
- Once on our mobile, we open it.
- We grant all the necessary permits for its proper functioning.
- We choose the network we want to analyze, for this we must enter it.
- we select “Scan”.
- A report will appear with SSID, IP, MAC address and the brand of the device.
List of the best tools to identify who is stealing the WiFi of your network
In order to identify the people who are connected to our WiFi network, we can use some of these applications:
Wi-Fi Inspector
This tool can provide us with reports of the devices that clandestinely connect to our wireless network. Some users have a negative opinion of this app, since it does not usually detect the name or type of intruder device in a concrete way, since it only shows generic names. But It is able to detect the MAC address and the 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 its main job is, the deep analysis and scanning of devices in the WiFi network. Once the entire network has been analyzed, it will show us the IP and MAC addresses of all the devices that are connected to our router at the time of the analysis.
It gives us the possibility of allow adding to devices connecting for the first time with our authorization to differentiate them from those who 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 any given time.
Thanks to the interface of this application it makes the operation very simple when it is already installed on iPhone or Androidfor this we are going to give the permissions that are necessary so that you can scan the WiFi network.
It gives us a list of all the devices that are connected to the network with MAC address, name and IP, as well as it can also show 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 on my wifi
Available for mobiles with Android operating system. It is an application very similar to the one we saw previously, since it is aimed at seeing who is connected to our wireless network. This is one of the simplest apps out there.
Its development allows us that once we access it and grant it the necessary access to make it work, it will begin to scan all kinds of devices that are connected to our wireless network.
When the scan is finished, it will show us a list of all the devices that are on WiFiwhich will be classified by their names, MAC address and IP address.
Wi-Fi Monitor
Another relatively new application, shares with Fing as one of the most complete that we foundin addition to being able to measure the upload and download speed thanks to its network scanner and provide us with a graphic report of the saturation of the network channels.
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 which 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 it is using at the time of the analysis, so It 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 of viewing the report with some extraordinary graphs that will show us the state of the network
Also, you can notify us immediately if someone connects to our WiFi. Available for Windows.
nmap
It is an open source tool that It will allow us to perform many tasks related to network analysis, being very prominent for its most common use, which is to detect who is connected to the wireless network. Also, you can trace the ports of the device.
This quite complete and very friendly app is not aimed at those who are beginners and want to use a simple application. It is available for Linux, Windows, and MacOS.
Wireless Network Watcher
To see in a simple way and with a few steps all the devices that are part of our WiFi network, we will only have to run this app. We will also know the IP address, device name, MAC address, number of times it has been connected, manufacturer, the first time it was connected and whether it is active or not.
To download this app we have two options, one is in file format “zip” and the information is complete, and the second in format “.exe”, which is the executable. Currently only available for Windows
wireshark
It allows us to monitor our WiFi networks and being a multipurpose application, we also have the option of deciphering the access password of neighboring networks.
When we get the report, it will show us the information related…
