You can see all devices connected to your fiber optic router by logging into the router's web interface, using command-line tools, or employing network scanning apps.

Using the Router's Web Interface

Most fiber optic routers allow you to view connected devices through their admin panel. To do this:

1. Find your router's IP address (commonly 192.168.1.1 or 192.168.0.1) from the router label, manual, or by checking your device's network settings .
2. Open a web browser and enter the IP address.
3. Log in with your admin username and password.
4. Navigate to sections labeled Connected Devices, Attached Devices, Client List, or DHCP Client Table. This will display each device's name, IP address, and MAC address .
5. Review the list to identify any unknown devices. If unauthorized devices are present, change your Wi-Fi password and use WPA2 or WPA3 encryption to secure your network .

Using Command-Line Tools

You can also check connected devices using your computer:

• Windows: Open Command Prompt, type arp -a, and press Enter to see IP addresses of connected devices .
• Mac/Linux: Open Terminal and type arp -a or route -n to list devices and their IPs . This method shows devices your router has communicated with recently.

Using Network Scanning Apps

Apps like Fing (iOS/Android) or Wireless Network Watcher (Windows) can scan your network and provide a detailed list of connected devices, including manufacturer and device type . Some router brands also offer dedicated mobile apps (e.g., TP-Link Tether, Google Home) to monitor connected devices in real time .

Additional Tips

• Most consumer routers support 32–64 simultaneous connections, while Wi-Fi 6 routers can handle more efficiently .
• Regularly monitoring connected devices helps maintain network performance and security.
• If you notice frequent unknown connections, consider enabling MAC address filtering or upgrading your router for better device management .
