How to tell if your WiFi is being stolen (and how to prevent it)

If you notice your internet browser doing strange things or that your connection service has declined Without an explanation, it is possible that someone has accessed your WiFi network. In this case, someone to whom you have not given permission to use your network occupies part of the bandwidth you have contracted. This of course slows down your network and can also pose a security threat.

When a third person connects to your WiFi, they will use some of your bandwidth and slow down the connection speed

In case you suspect that a third person is using your connection, there are several steps you can take. You can superficially fix this by changing your password or doing a deeper verification.

-Change Password: As I said, it is the easiest way to solve the problem, if only temporarily. Changing your WiFi password prevents people who have occasionally been given a password or who just guessed it out of luck from entering your network. When setting a new password, there are a number of factors to consider to keep it secure.

But if someone has hacked your wifi and can crack a password, sooner or later they will do it again when you change your password.

-List of connected devices: If you want to go a step further and check your router’s security settings, this is a good place to start. If you have a computer with a Windows server, you can use the Wireless Network Watcher application.

This program, developed by Nirsoft, can be downloaded for free from its website. It is a program that you install on your computer and analyze your network. It contains information such as: B. what devices are connected to it, how often they are connected and their IP and Mac addresses.

If you are using a Mac, the LanScan application does the same thing. There are also mobile applications like Fing that allow you to check the entire history of connections to your network.

-Router Settings: If you access your router’s settings web, you can access information about it and change aspects of its configuration. To enter it, everything you need can generally be found on the back of the router. Generally, you need to enter your ISP’s website and type your IP into a search engine.

In the router settings, you can change the name or password of the WLAN and view the list of connected devices. In the most modern routers, they even tell you the brand of the device, whether it is a phone or a computer that has been connected to the network.

-Prevent it from happening again: While you may be unlucky to have a hacking neighbor who can crack your password for whatever it is, the wifi thief most likely found your password by accident.

To prevent this from happening again, it is best to use a strong password. This is done, for example, by not using your name, address or year of birth in the password. You also don’t want the password to be similar to the name of the network.
