5. Operating Instructions

5.1 Connecting to Wi-Fi

Your MT7711 broadcasts two Wi-Fi networks: 2.4 GHz and 5 GHz. The default Wi-Fi network name (SSID) and password are printed on the label on the bottom of your modem router.

1. On your wireless device (smartphone, tablet, laptop), open the Wi-Fi settings.
2. Select the Wi-Fi network name (SSID) corresponding to your MT7711.
3. Enter the Wi-Fi password (security key) when prompted.
4. Your device should now be connected to the internet via Wi-Fi.

For optimal performance, devices closer to the modem router and capable of 5 GHz Wi-Fi should connect to the 5 GHz network. Devices further away or older devices may perform better on the 2.4 GHz network.

5.2 Guest Network Access

The MT7711 supports a guest Wi-Fi network, allowing visitors internet access while keeping your main network private. Details on enabling and configuring the guest network can be found in the full user manual or by accessing the modem router's web management interface.

5.3 Using Telephone Service (Xfinity Voice)

If you have Xfinity Voice service, ensure your analog telephones are connected to the TEL1 or TEL2 ports. The MT7711 supports enhanced call features such as caller ID, call forwarding, and conference calling, as provided by Xfinity.

6. Maintenance

• Placement: Place the modem router in an open, central location to maximize Wi-Fi coverage. Avoid placing it near large metal objects, concrete walls, or other electronic devices that may cause interference.
• Ventilation: Ensure the modem router has adequate ventilation. Do not cover ventilation openings or place it in an enclosed space.
• Cleaning: Clean the device with a soft, dry cloth. Do not use liquid cleaners or aerosols.
• Firmware Updates: Firmware updates are typically managed automatically by your service provider (Xfinity). Do not attempt to manually update the firmware unless instructed by support.
