How to optimize the ZTE MF79U for stable internet connection

  1. Initial Setup

    • Connect the ZTE MF79U modem to a USB port on your computer or a USB power source. It will automatically power on and create a Wi-Fi hotspot.

    • Connect your device (smartphone, tablet, or PC) to the Wi-Fi network broadcast by the modem. The SSID and password are found on a sticker under the modem’s cover.

    • Access the modem’s configuration page by opening a web browser and entering the default IP address 192.168.0.1. Log in using the admin password on the sticker.

  2. Network Configuration

    • Within the web interface, check the network signal strength and type from the homepage.

    • Navigate to “My Router” → “LTE Settings” → “Network Selection” to choose between automatic network mode or force the modem to connect to a preferred network type like “4G Only” for maximum speed or “3G Only” or “2G Only” for greater stability in weak signal areas. Apply the settings to optimize connectivity.

  3. Antenna Optimization

    • The ZTE MF79U supports external antennas via two TS-9 ports. Attaching external antennas and positioning them in locations with better signal reception (e.g., outdoors, higher locations) can significantly improve signal quality and connection stability. You can monitor the signal level in the web interface to fine-tune antenna placement.youtube

  4. Additional Tips

    • The device supports up to 10 simultaneous Wi-Fi connections, so limiting connected devices can reduce bandwidth congestion and enhance performance.

    • Regularly update the firmware through the modem’s web interface if updates are available to benefit from performance improvements and bug fixes.youtube

    • Use the manual mode in the network settings if you want to avoid automatic network switching during the session.
