ZTE F660 and F6640 Admin Password Guide: A Step-by-Step Approach

Introduction: The ZTE F660 and F6640 are popular fiber-optic modems used for high-speed internet connectivity. Accessing the device's administration panel allows users to configure settings, enhance security, and troubleshoot issues. However, many users struggle with the admin password, especially if it's an "exclusive" or default password that hasn't been changed. This guide provides a comprehensive overview of default passwords, how to reset them, and tips for securing your device. Connect via Ethernet (WiFi may disconnect during reboot)

Method A: The Hidden Login Page

Do not use the default login page. Use the CU (Control Unit) hidden path.

  1. Connect via Ethernet (WiFi may disconnect during reboot).
  2. Open your browser and navigate to: http://192.168.1.1/cgi-bin/login.asp
  3. Enter root and Zte521.
  4. If successful, you will see a grey/blue menu with "Network," "Security," and "Diagnostics" far beyond the standard menu.

The "Exclusive" Backdoor (Telnet Required)

The real exclusive password isn't for the web portal; it's for Telnet (Port 23) . Even if the web admin is locked, Telnet often isn't.

  1. Enable Telnet via your browser: http://192.168.1.1/cgi-bin/telnet_enable.cgi
  2. Open Command Prompt and type: telnet 192.168.1.1
  3. Login with:
    • Username: root
    • Password: root (Yes, double root) OR Zte521@CLI

Admin Password

The admin password for ZTE F660 and F6640 routers is usually set by the ISP or the user during the initial setup. If you've forgotten the admin password or are looking to reset it, there are a few methods you can try:

  1. Default Credentials: Most ZTE routers, including the F660 and F6640, come with default admin credentials. Typically, the username is "admin," and the password can vary, often being "admin" or "1234." However, these can be changed by the ISP or during setup.

  2. Reset to Factory Settings: If you can't remember the admin password, you can reset the router to its factory settings. There's usually a small pinhole reset button on the back or bottom of the router. You'll need a pin or a paperclip to press and hold this button for about 10-15 seconds. This action will reset all settings, including the admin password, back to their defaults.

  3. ISP-Specific Passwords: Some ISPs customize the admin interface and set their own default passwords. In such cases, contacting your ISP's customer support might be the easiest way to gain access to your router's settings.
