Detection

The easiest way to know who is connected to our network is through different programs, known as ‘sniffers’ or network scanners, installed on our own devices. From the mobile, tablet or computer with which we usually connect to the internet at home, we can obtain a list of all the devices that are using the same network at that moment.

One of the most recommended by users is fing, available for both Android and iPhone. But there are many other applications for tablets or mobiles and for computers, Who is on my Wifi either Wireless Network Watcher are two of the most used.

One way to know if someone is using our Wi-Fi is to disconnect all our devices and see if the light on the router continues to blink. If it does, it’s clear that someone is using our network.

It is also possible to know if someone has used the Wi-Fi in our absence. To do this, you must access the router’s website, which is done as follows:

  1. you put the router address (usually, 192.168.1.1 either 192.168.0.1) in the web browser. Thus, a website is accessed in which we are asked for the username and password of the router.

  2. Consult the history of devices that have been connected. There appears a list with IP and MAC addresses of the devices. Knowing ours, you can check what others have connected without your knowledge.
