To check the IP addresses connected to your Wi-Fi, log into your router's admin panel. Open a browser and enter your router's gateway address, commonly 192.168.1.1 or 192.168.0.1, then sign in with your admin username and password. Once inside, look for a section labeled Connected Devices, Attached Devices, or DHCP Client List, which will show every device currently on your network along with its private IP address, device name, and MAC address. Reviewing this list regularly helps you spot unfamiliar devices that might indicate unauthorized access to your Wi-Fi. If you see a device you do not recognize, you can usually block it directly from the same admin panel, and it is a good idea to change your Wi-Fi password afterward.
