Currently, a WiFi router is essential in a home, whether you work directly online, use the internet to finish office work, do study reports, play games or communicate, so you always have to keep it in perfect working order. One of the things that influences the most in this regard is the number of devices that connect at the same time..
Each device that connects implies an extra data consumptionwhich can make network speed slows down. That is why you should be aware that no third party takes advantage of you by connecting to your internet without your consent. Doing the latter is very easy, you just have to apply some security measures in the configuration of your router.
In this article we will teach you how to decrypt if there is already someone connected to your network without your wanting to., and all the necessary security measures so that it does not do it again once you discover them. In the end you will have learned everything you need to know until you become an expert in WiFi security.
How do I know if my WiFi is being stolen?
If your internet is slower than normal or the invoice shows more expenses than you think you make when browsing, it is likely that someone has been connected without your authorization, if you suspect that this is the case, before ending it you must find out that it is true. To find out if someone has connected and has been stealing your you can do the following.
- Search at the start of Windows CMD and open it.
- In the window with a black background that will appear, write “ipconfig” and press enter, you will get some words and you should look for a part that says “Default Gateway” next to some numbers, copy the numbers.
- Open the browser, paste the numbers and go to the address.
- You will be entering the , so it will ask you for data to access. If you don’t know, check on the back of the router or try the ones that come predetermined from the factory for all types of routers such as admin/admin, admin/1234.
- Inside the configuration interface, go to the panel and click “dhcp”Then in “dhcp client list” and there will appear all the devices that have connected to the router as well as their IP, mac, how long they have been connected and the configured name of the device. So you can search for the IP of each device in your home and verify that no one else has connected to them.
On the other hand, you can also look at the internet speed. Wireless connections tend to lose stability and speed as more devices are connected to it. So if there is a third party using yours, it is likely that you notice that the internet is slower.
Finally you can look at the router lights. There are some that keep blinking while we are using the connection and are a sign that the equipment is sending and receiving data, but when nobody is using them, they remain static either on or off. what you can do is disconnect all the devices in your house and wait a few minutesIf you notice that the lights continue to flash after that, you can bet someone else is using your network at the time.
Steps to protect and block the Wifi signal from intruders and unwanted users
If you are sure that someone has been stealing your connection and you want to stop it or you simply want to take preventive measures to prevent strangers, intruders or malicious users from connecting and taking over your data or using your internet without your permission in the future, You can carry out certain configurations within the administrator panel of the router.
These measures that we are going to explain are easy to carry out, they are not require extensive knowledge of technology or computing and are effective for Wi-Fi security, because normally the emitters are configured with basic details that make them very vulnerable. However, you can try any of the ways of protect your WiFi signal that we show you and improve that factory security.
Changing the password
One of the reasons it’s so easy for strangers to connect to your WiFi without your permission is because all routers from the same manufacturer come with the same factory password, so ifIf they know the brand of the router and you have never changed the password, it will be a piece of cake to connect. Although it is also possible that you have given it to one person and they have told it to many more. In any case, by changing the password you can be a little more protected and avoid this, to do so you must
Access the configuration panel of the router and then in the panel go to “Wireless”there choose “wireless security” and all your security settings will appear, including the password, which you can easily change by tapping and typing the one you want.
Change the SSID or network name
Surely if you have not made changes your network has the name of the router’s factory brand. If so, you have no idea what an opportunity you have given to strangers. In addition to letting them know the default password easily, Just by knowing the manufacturer, strangers can try to enter the configuration panel and edit all the operating details. to make their connection better than yours or anything else.
Either way, this puts you at risk, so it’s time to change that name. For that you need to do the following. Look among the options, the tab “Wireless“, there choose “Wireless Settings” and click. You will get all the basic configuration information, mainly the name of the network, touch, delete it and place the one you want.
Change the access credentials to the router
Another very effective security measure is change the access credentials to the configuration panel of your router. In this way you prevent a third party from getting into it and making changes to their liking without your consent, which can cause you to no longer be able to use the network normally. The steps to do that are very simple to apply.
What you have to do is enter the settings interface and go to the “System Tools“and in it he searches”Password“. This is where you will be able to set a new password and username for . Without these you will not be able to log in in the future, so we recommend that you keep them in several places.
How to audit your WiFi network to detect possible vulnerabilities and security holes?
Auditing the WiFi network is possible through hacking applications or software. The number of this type of programs is very large, there are many for each operating system, whether Android or iOS, in the same way there are some for Windows or MacOS computers.
However, the effectiveness of these in getting someone access to your connection depends a lot on the person’s knowledge of technology and computing. Basically for those who know how to do it, it is very possible that they manage to steal your internet. In the case that we want to use these apps to detect vulnerabilities and verify that the network works as it should without anyone connecting without your permission, it is very easy. It is enough to know the safe software and install it.
Next we will explain what are the best programs and how to use them so that no one steals your WiFi.
From Android apps
From your mobile you can download a hacking App to see what those who try can see, so you will know if they manage to connect with applications and will detect any configuration failure that is putting your privacy and your connection at risk.
Among several, users prefer wpsappIt is very intuitive and easy to use. What WPSApp does is encrypt WPS network pins. Upon entering, and activating it, you will get a list of nearby networks and next to the name a ticket between green and red. If it is red it means that you will not be able to access the key, while if it is green it means that you could provide the key. Verify that your home network has a Red ticket with this app.
However, in addition to the popular WPSApp, there are other alternatives that also work correctly. Among them, I recommend the following.
- Wps Wpa Tester Premium: This app available for Android versions greater than 5.0 uses a series of algorithms to crack the password of a WiFi network. In the menu it shows which ones it can decrypt and which ones it can’t. Make sure yours is in red.
- AndroDumpper: Like most similar apps, Andro Dumpper allows you to verify at a glance which networks are vulnerable and from there provide the key. Verify that yours is never possible to crack.
- Router keygen: the interface of this is a little different from the others but it also shows which networks it supports and can give access to, it also shows detailed information on the security of the network. In case we own a network we can use this information to improve security.
From the computer
As in mobile phones, for computers it is possible to install and use programs that are capable of providing information and reveal the password of a WiFi. To realize that our network is not vulnerable, the best thing we can do is test these systems.
That’s why I recommend you try Dumpper, which is currently the best method to hack WiFi networks from a PC. It is enough to install it and the program will scan a detailed list of nearby networks, if you touch any of them you will get all the information of its configuration as well as the possibility of connecting after the program deciphers the pin.
Apart from dumperwe know of other good ones, try all of the ones on the following list and make sure that none of them allow strangers to browse on your service.
- Acrylic: It is a modern and stylish software that looks for the name of the network, the MAC address and the type of encryption to try to provide keys by default, so in many cases it is ideal to know if we still have any factory settings that we must change on our router.
- Feeding Bottle: allows you to scan Wi-Fi networks with passwords and through its graphical interface the program uses algorithms to decipher the access code and the detailed security information of the network.
- MinidWep: With an easy-to-use interface, this app uses several methods to access the information of a router and to be able to scan all the details including the connection key.
