A router is a network device that provides a stable Internet connection and can connect computers together. Most often it is connected to the DSL connection. The router shares the Internet signal with other computers and smartphones via a WLAN signal. To be able to receive the WLAN signal, a password or so-called WLAN key must usually be entered in the device settings. The devices are then all on the same network. This allows information to be exchanged via the WLAN among the devices registered in the home network.
