1. Use a Network Scanning Tool: Most network scanning tools will allow you to scan your network to detect any unknown devices. This can be done by entering the IP range of the network, and the tool will do the rest.
2. Check Your Router’s DHCP Client Table: Most routers will have a web–based control panel where you can view the DHCP clients table. This table lists all the devices that are connected to your router and the associated IP addresses.
3. Check Connected Devices: You can also manually check each connected device to make sure it is one you recognize. For example, if there is a device that has an unknown IP address, try to access it via its IP address or MAC address.
4. Implement Network Security Solutions: You can also consider implementing security solutions such as Network Access Control (NAC) or IEEE 802.1x authentication to ensure that only known devices are allowed on your network.
