1. Inserting the SIM Card

  • Insert the SIM Card: Ensure that the SIM card does not have a PIN code and insert it into the device.

2. Connecting to the Wi-Fi Network

  • Connection: Turn on the ZTE MF920U router. Find the Wi-Fi network created by the router. The Wi-Fi password consists of eight characters and is indicated on the back of the device. Connect to this network.

3. Accessing the Web Interface

  • Access the Router Menu: Open a browser on your smartphone or computer connected to the router's Wi-Fi network and enter 192.168.0.1 in the address bar.
  • Switching to the PC Version: If you're using a smartphone, after logging in, find the "PC" button at the bottom of the page and click it to switch to the full version of the interface.
  • Authorization: Enter the administrator password found on the back of the router (e.g., Password: RzjP75Ad).

4. Checking the Network Signal

  • Signal Check: In the main menu of the web interface, you can see the signal strength and the type of network connected (2G, 3G, or 4G).

5. Forcing the 4G Only Network Mode

  • Disconnecting the Current Network: In the main menu, find the green "ON" switch next to the network type and click it to disconnect the current connection. The switch will turn gray with "OFF" displayed.
  • Selecting the Network: Go to "Settings," then "Network Selection." Choose "4G Only" to force the router to connect to the 4G network and click "Apply."
  • Reconnecting: Return to the main menu and turn the network back on by clicking the gray "OFF" selector.
Why Choose 4G Only Mode?

Forcing the 4G Only mode ensures stable connectivity to the 4G network, which is particularly important when the router automatically switches between 2G, 3G, and 4G networks. This helps prevent connection drops and slow data speeds.

6. Connecting Mobile Guard Antennas

  • Connecting MIMO Antennas:
    1. Connection: The ZTE MF920U router supports MIMO (Multiple Input, Multiple Output) technology, allowing you to connect two antennas simultaneously for signal enhancement. Connect two Mobile Guard antennas to the TS9 ports on the router.
    2. Directional Antennas: Install both antennas at a height and aim them at the nearest base station to achieve maximum signal strength.
    3. Radial Magnetic Antennas: If using radial antennas, place them on a metal surface for stable signal reception from all directions.
Advantages of Using Two Antennas with MIMO Technology

MIMO technology allows the use of two antennas to improve connection quality and increase data transmission speed. Benefits include:

  • Increased Throughput: Simultaneous data transmission through two antennas increases connection speed.
  • Better Signal Reception: Two antennas provide more reliable connectivity in areas with weak coverage.

7. Device Usage Recommendations

  1. Optimal Placement: Place the router in areas with the best network coverage, such as near a window or in an elevated position.
  2. Using Antennas: If the signal is weak, connect directional or radial Mobile Guard antennas via TS9 ports to enhance the signal.
  3. Forcing 4G: To ensure a stable connection, set the router to use only the 4G network.
  4. Firmware Updates: Regularly check for firmware updates via the web interface to maintain stable device operation.
  5. Network Security: Be sure to change the default password for the Wi-Fi network and the router's web interface to protect against unauthorized access.
