Step-by-step secure Wi‑Fi settings for ZTE MF673

Here is a step-by-step guide to configure secure Wi-Fi settings on the ZTE MF673 router:

Step 1: Access the Router Interface

  • Connect a device to the MF673 via Wi-Fi or USB.

  • Open a web browser and enter the default router IP address, usually 192.168.0.1.

  • Log in with the default credentials (username: admin, password: admin or check device label).

Step 2: Navigate to Wi-Fi Settings

  • From the main menu or dashboard, find and click on Wi-Fi Settings or Wireless Settings.

  • This section manages SSID, security mode, password, and network parameters.

Step 3: Change the Default SSID

  • Locate the field labeled SSID (network name).

  • Change the SSID to a unique name that does not reveal personal info.

  • Save the changes.

Step 4: Enable Strong Security Mode

  • Under Security Mode or Encryption, select WPA2-PSK (Wi-Fi Protected Access 2 – Pre-Shared Key).

  • WPA2 is currently the most reliable and secure encryption for 2.4 GHz Wi-Fi networks supported by the MF673.

Step 5: Set a Strong Wi-Fi Password

  • In the Password or Wireless Key field, enter a strong password.

  • Use a minimum of 12 characters including uppercase, lowercase, numbers, and symbols.

  • Avoid common or predictable passwords.

Step 6: Disable WPS (Wi-Fi Protected Setup)

  • If available under Wi-Fi or Security settings, disable WPS.

  • WPS can be vulnerable to brute force attacks, disabling it improves security.

Step 7: Save and Apply Changes

  • Click Save or Apply to update Wi-Fi settings.

  • The ZTE MF673 will restart Wi-Fi services with the new secure configuration.

Step 8: Reconnect Devices

  • Reconnect all devices to the new SSID using the updated strong password.

Optional: Advanced Security Settings

  • Change the router admin password from the default to a strong, unique one.

  • Disable broadcasting the SSID if you want to hide the network, but this may affect convenience.

  • Enable firewall and any other security features available in the router settings.

Following these steps ensures the ZTE MF673 Wi-Fi network is protected against unauthorized access and keeps data secure while connected.

Firmware Update

  • Connect the MF673 to Wi-Fi.

  • Access the router’s web interface via the browser.

  • Navigate to “Settings” > “System” > “System Update.”

  • Choose to update online or download the firmware from ZTE’s official site for offline update.

  • Follow on-screen instructions to complete the update while keeping the device powered.

Common Problems

  • Connectivity issues such as limited or no internet access despite Wi-Fi connection.

  • IP conflicts within the network causing inconsistent internet performance.

  • Battery performance degrading over time.

  • Occasional firmware errors requiring re-flash or update.

  • Some users report issues with device dead boot, requiring specialized fixes or support.
