6. Operating Instructions
6.1 Connecting to Wi-Fi
To connect your wireless devices to the TG2472G's Wi-Fi network:
- Locate the Wi-Fi Network Name (SSID) and Password (Network Key) on the sticker on the bottom or side of your gateway.
- On your wireless device (smartphone, tablet, laptop), open the Wi-Fi settings.
- Select the SSID that matches your gateway's network name (e.g., "ARRIS-XXXX").
- Enter the Wi-Fi password when prompted.
- Your device should now be connected to the internet.
6.2 Accessing the Web Management Interface
The TG2472G features a web-based management interface for advanced configuration:
- Ensure your computer is connected to the gateway via Ethernet or Wi-Fi.
