Today the theft of WiFi is one of the most practiced things in the world and thanks to technological advances this is something that can be done more and more easily. It is important to mention that all users always take precautions to prevent their wireless network from being breached by intruders and thus stealing the signal from it.

All this is known as hacker , and nowadays this is something that cybercriminals practice for both the wireless connections of big companies, banks, institutions and homes. Therefore, your Internet connection could also be put at risk if you don’t have adequate security to prevent these possible accesses by outsiders.

Nowadays there are infinite methods with which you can violate the security of your connection . However, there are also different ways in which you can defend yourself against cybercriminals trying to access your WiFi network. So here we’ll show you the main methods to improve and protect your wireless signal from hackers . To do this, just follow the steps below.


Steps and methods to improve and protect our wireless internet network

Protecting the wireless network in the home or workplace is one of the most important things when it comes to wanting to have optimal Internet performance . You must bear in mind that the moment your Internet is stolen it will start working much slower. Therefore, you will start to have a lower performance.

So this will start to become a problem for you, that’s where the importance of being able to have a secure wireless signal comes in, which can’t be reached by anyone and of course in the hands of malicious and expert hackers.

Because of all this, most users are constantly investigating what are the main methods with which to protect these connections, it is important to note that there are thousands of ways to do this, some more effective than others. That’s why here we’ll show you some methods to help you do this:

Change the default user and password

Cambiar el usuario y la contrase¤a por defecto

Please note that using the default username and password will not bring any security to your connection, this can easily be breached by a hacker with expertise in the area or simply by logging in to the Internet and searching for passwords and usernames for router flaws could come up on your network.

Because of this, it is essential that you change both the user and the password. It is recommended that you use passwords of at least 8 characters and that you combine it between upper and lower case letters, symbols and numbers in order to make it as secure as possible.

Change SSID

Cambiar SSID

The SSID identifier is one of the most basic configurations of all routers for WiFi connection . However, the use of it turns out to be too common, it usually always has the name of the provider, which will make it much easier for cybercriminals to be able to break the security parameters to try to get into it.

An example of this would be TP LINK wireless routers, commonly the SSIDs of them usually have a name like TP LINK followed by the model number of the equipment.

These SSIDs almost always end up giving more account information which can end up being a problem for the security of your Internet network. And that’s because the encryption algorithms that are built into the SSIDs , and the password dictionaries that are used by hackers are preloaded with the most common SSIDs. So it’s quite possible that they can get access to yours.

The most advisable thing to do in this case is to change the default name and to put one that is easy to remember , it is also not recommended to put a name that identifies the house or the family, the more incognito it is the better for your security. You will even have the opportunity to hide the entire SSID as long as your computer model allows you to perform this step.

Control and limit WiFi network coverage

Controlar y limitar la cobertura de la red WiFi

Identity and internet theft is on the rise , this makes users increasingly want to have better security in their wireless networks. One way to prevent or control this is by limiting the network coverage , it is generally recommended that this is not overly far reaching as the idea is not to offer a WiFi connection to a large number of people but simply to cover the area of the home or office.

Please note that if your wireless coverage is long distance, anyone with a laptop or Smartphone can access a connection, either to spy or to carry out some illegal activity. Therefore, it is essential that you can limit this, preferably only covering the area of your home.

This can be done as follows:

  • The first thing you need to do is to know how far your network can reach. To do this you can start walking with your mobile phone along your house , either in the garden or outside, there you will see the WiFi icon with the range signal where you can measure how far the signal covers.
  • Once you know how far your router’s coverage goes, you have to move it to a different location, the best option to be able to limit the coverage is to place it in the center of the house, likewise you can try placing it in different places.
  • The next thing is to change the orientation of the modem antennas, these have to point in a direction opposite to your neighbors’ houses or the street. If you have two antennas, you can remove one of them so that it sends less signal, since you only want it to cover the area of your house.
  • Most current equipment features the “Radio Power” option which can reduce the signal by up to half.
  • And finally you can use the special wall paint to block the signal, this way you will prevent the coverage from reaching long distances where it might be in reach of intruders.

Deactivate UPnP

Desactivar UPnP

The UPnP, is a communication protocol between the private network and the devices and one of its main functions is to open the ports automatically without the need for the user to configure the router directly .

Routers have incoming ports that are closed for security reasons , otherwise they would end up being easy targets for malware who could access the open ports. But you should be aware that with applications that support UPnP you will be able to open these ports to any local network, but this is where the problem lies, as many malware can also support these UPnPs.

Therefore keeping them activated may prove to be a safety risk. It is generally recommended to keep off the UPnP and instead use DMZ Host which is a simpler configuration to be able to open the ports and has no security risk as the ports are automatically redirected to the Virtual Servers.

Update the firmware

The firmware updates are a fundamental tool for the smooth running of the router , this will allow you to correct any errors as well as make any necessary improvements to the equipment. Keeping your router up to date will help you to have a good use and control of your wireless network and to be more protected from hacker attacks.

Updating the firmware is usually really easy so here we explain how to do it, please note that before you start the process you need to download the latest firmware version to your computer, once it is downloaded you can start the update, to do this you will need to perform the following steps:

  • To start, you need to start your preferred browser, in the “Search Bar” you will enter “” and then press the “Enter” key . If this address doesn’t work you have to check the IP address of the router, it’s usually on the back of the device.
  • Now you have to enter your login details, the username and password , if you have never changed them you can try “Admin” for both boxes.
  • Once you are logged in you have to click on “Administration” and then on “Firmware” .

  • Once you are in the “Firmware” section you have to select “Browse”.
  • A window will appear where you have to search for the previously downloaded version and finally you give it “open”.
  • Click on the “Start Upgrade” button to start the upgrade.
  • After a few seconds this will have been updated and the process will have been completed.

Turn off the WiFi if you are not going to use it

Apaga el WiFi si no lo vas a usar

Another alternative you can use in case you want to prevent others from stealing your wireless network is to turn off the WiFi if you are not using it , so that you can avoid the risk of others trying to access it.

This is usually used when you are at home, so every time you leave your home or office you can disconnect it or before you go to sleep , this way you will be preventing other users or your own hackers from violating your security and accessing your Internet connection.

Have a secure encryption

Disponer de un cifrado seguro

One of the most important tools for the security of your WiFi equipment is the encryption of the data that will be transmitted on it. It is therefore essential to be able to rely on completely secure encryption. Currently the new router models have three systems or protocols; WEP, WPA and WPA2.

Today the WEP protocol is no longer used, or is used very little, generally if you have the possibility to choose the system yourself it is recommended to choose WPA or if it is available to use WPA2 as it is the most modern and therefore will give you the most security.

Having a WPA2 protocol will help you to have a more secure wireless signal , as offers you very high levels of security . But, it is important that before you want to make use of this system to verify if the equipment you are using can support it, this you can know in an easy way, if your equipment is old the most probable thing is that it does not support it, but if you have a new router you can use it without any type of problem.

It is important to note that whichever one you choose, the most important thing in these cases is to be making a constant key change, either every 30 days or maximum every 60 days so that you can prevent unwanted people from accessing your network.

Activate MAC filter from the router

Activar filtro MAC desde el router

This will allow you to create your own list of allowed devices so that they can use your network, thus giving you more security. The MAC filter is currently considered to be another of the most useful security methods for the router.

With this method you will be able to manage a little more what will be the access to your WiFi network, especially today when most people have a Android or iOS device that can access any wireless signal at any time they want.

It is important to mention that if the network is blocked it can restrict the access of the majority but, nowadays there are many ways to be able to violate this security and access the network, which has long been known as a hacker with bad intentions.

The MAC is a protocol that serves as a network card for the devices , whose main function is to be able to identify them in order to authorize the transmission of information and to the organization.

By activating this filter you can guarantee that only the devices and laptops you authorize will make use of your wireless network, thus making it much more secure.

Another option you can make is to use the monitoring tool for your router , as an overloaded computer can make communication much slower . So monitoring it can be a very good option, this will allow you to know all the connections of the computer, determine the bandwidth, the devices connected to it, the amount of traffic , among many other things.

With this tool you will be able to have more control over your computer , you will be able to know what factors may be affecting the operation of your computer and know how much of your device is linked to the router. All this will make your job much easier as you will want to improve and have better performance from your wireless connection.

How do I know if my Wi-Fi network is being used by someone else?

Como saber si me roban el wifi

Knowing for sure if other people are stealing your WiFi connection can be a bit tricky, as this is somewhat difficult to achieve. However, there are different clues that can help us to deal with this type of question .

This is not only about third parties who may access your connections, but also about cybercriminals who may generate identity or bank data theft. This is why it is important to always be aware of who is using your WiFi or not.

Some of the main indications that will allow us to know this kind of thing or at least to be suspicious are the following:

  • One of the ways you can find out if other people are using your WiFi network is by looking at the behaviour of your Internet connection. Usually, if you had a fast internet all the time and suddenly it started to fail, it’s much slower, it could be that other people are stealing your signal, which is creating interference that doesn’t let the service work properly, as it makes much heavier and slower.

However, it is important to note that this problem can also be related to other aspects , whether is network problems, especially if it is a rainy day, or service or router problems .

  • Another way to check this is to use one of the free online tools that will let you know if your wireless connection is being stolen, these tools are available for Windows and Mac, and for Android and iOS devices.

However, these tools are usually not the best tools to be able to determine this with complete certainty but they can give you an idea if you are lucky enough to know if there are other people using your Internet.

The problem with these applications is that they only allow you to see the computers that are connected at the moment, that is to say, if you enter an hour later and the users are connected you will be able to see it , but if they are not, simply no one will appear, that’s where we refer to the term luck.

In spite of this, this type of tool is still an option to be able to clarify this type of doubt.

  • Another way to find out if there are other people using the wireless network is to completely turn off all devices in the house so that none of them are connected to the network. Once this has been done, check the flashing lights on the router , if it continues to flash it is quite possible that there are other people using the WiFi network.

If this happens the first thing you have to do is change the computer key so that all devices linked to it are automatically disconnected.
