01 Connected devices
The modem/router combination knows exactly which devices are registered on the network on the basis of IP addresses. Surf to the IP address of the router, in many cases that is //192.168.1.1. Then log in to the administration panel with a username and password.
If you don't know the details, look in the manual of the device. You should request a list of the IP addresses of connected devices somewhere in the menu. For example, with Cisco routers, you can navigate to Setup / Lan Setup / Connected Devices Summary. The device name is usually listed after the IP address.
Conveniently, you can see exactly whether the equipment is connected via Ethernet or WiFi. Are all unknown IP addresses and names visible? High time to take action! In the answer to question 6, we explain in detail how to secure the WiFi network.

Earlier we mentioned the program Wireless Network Watcher, with which you can see the IP address, MAC address, manufacturer and device name of every device. This time we call SoftPerfect Wifi Guard, because this program quickly detects whether foreign devices are registered in the network.
With SoftPerfect Wifi Guard you can continuously monitor whether there are no intruders on the network. Surf to the website and download the program to your PC.

After a few seconds, a list of devices that are active in your network will appear. In addition to the IP address and device name, you can also see exactly who the supplier is. It is useful that you indicate that you are the owner of known devices. To do this, right-click on the IP address and select Properties. Check the box for This computer or device is known to me and confirm with OK.
