There are several methods for this, the most basic of which is to use the router itself or the modem. This is possible because most routers have a status page or a configuration page that shows all the devices connected to the network.
On this page you can View things like device names, their IP addresses, and their connection status.
Another way to find out who is connected to a Wi-Fi network is by using network scanning software such as Fing or Angry IP scanner, these programs search for devices connected to a network and display information about the found devices, including their IP address and their manufacturer. can also be use mobile apps to scan WiFi networks and see what devices are connected.

For this point, it is important to have the IP address that was previously obtained when performing the scan to detect devices connected to the WiFi network.
