Your router is the gateway between your home network and the internet, making security a priority beyond the initial setup. To begin securing your device, log into the admin panel by typing your router's IP address (often 192.168.1.1) into a browser. If unknown, find it via Command Prompt on Windows using ipconfig or by holding the Option key on a Mac to view the Wi-Fi icon.

Change default credentials immediately, as "admin" is the first username hackers attempt. Update your network name (SSID) and password to avoid using the model name, which reveals potential weaknesses. For wireless security, set Authentication Method to WPA3-Personal for the strongest standard; if incompatible, use mixed WPA2/WPA3 mode.

Utilize the guest network feature to isolate smart home devices or children's devices, preventing them from accessing your main network resources. Many routers allow bandwidth limits or time restrictions for guest access. Because guest networks have separate passwords, you can use simpler credentials while keeping your primary password complex and secure.
