ZTE F670 Manual: A Complete Guide to Setup, Configuration, and Troubleshooting

The ZTE F670 is a high-performance Gigabit Premium Triple-Play GPON gateway. Whether you are setting it up for the first time or trying to optimize your home Wi-Fi, understanding the ins and outs of this device is essential for a stable internet connection.

This guide serves as a comprehensive manual to help you navigate the features and settings of your ZTE F670 ONT (Optical Network Terminal). 1. Hardware Overview and LED Indicators

Before diving into the software, it is important to understand the physical layout of the device. Port Descriptions: PON Port: Connects to the fiber optic line from your ISP.

LAN Ports (1-4): Used for wired connections to PCs, gaming consoles, or routers. TEL Ports (1-2): For VoIP phone services. USB Port: For media sharing or network storage. Power Port: Connects to the 12V DC adapter. LED Indicator Meanings: Power: Solid green means the device is on.

PON: Solid green indicates a successful fiber connection. Flashing means the device is attempting to register.

LOS (Loss of Signal): If this is flashing red, there is a break in the fiber line or a signal issue. Internet: Solid green means you are connected to the web. WLAN: Indicates the 2.4GHz or 5GHz Wi-Fi bands are active. 2. Accessing the Web Management Interface

To change your password or manage settings, you need to log into the ZTE dashboard. zte f670 manual

Connect your computer to the ZTE F670 via Ethernet cable or Wi-Fi.

Open a web browser and type the default IP address: 192.168.1.1 (some ISP versions may use 192.168.0.1). Enter the login credentials. Default values are usually: Username: admin

Password: admin (or the password printed on the sticker at the bottom of the device). 3. Wi-Fi Configuration (SSID and Password)

Since the ZTE F670 is a dual-band router, you can configure both the 2.4GHz and 5GHz bands. Navigate to the Local Network tab. Select WLAN from the left-hand menu. Go to WLAN SSID Configuration.

Choose the SSID you wish to change (e.g., SSID1 for 2.4GHz). Update the SSID Name and WPA Passphrase. Click Apply to save changes. 4. Advanced Settings Port Forwarding

If you are gaming or hosting a server, you may need to open specific ports. Go to Internet > Security > Port Forwarding.

Enter the Name, Protocol (TCP/UDP), and the Local IP of your device. Input the Start and End ports provided by your application. Parental Controls Navigate to Internet > Parental Control. ZTE F670 Manual: A Complete Guide to Setup,

Here, you can create rules to limit internet access for specific devices based on a schedule. 5. Troubleshooting Common Issues No Internet Connection

Check the LOS light. If it’s red, contact your ISP as the fiber cable might be damaged. Restart the device by unplugging the power for 30 seconds. Slow Wi-Fi Speeds

Ensure the router is in an open area, away from metal objects.

Use the 5GHz band for high-speed tasks, as it has less interference than 2.4GHz.

Change the "Channel Width" to 40MHz (for 2.4GHz) or 80MHz (for 5GHz) in the WLAN Advanced settings. Forgot Login Password

If you can't access the dashboard, find the small Reset button on the back/side.

Hold it down with a paperclip for 10 seconds while the device is on. This will restore all factory defaults. Summary Table of Default Credentials Default Value Gateway IP 192.168.1.1 Username Password Wi-Fi SSID ZTE_XXXXXX Wi-Fi Key See device sticker Log in to the web GUI

Note: For security reasons, it is highly recommended to change the default admin password immediately after your first login.

6. Factory Reset (When Everything Fails)

If you forget your custom password or mess up settings, a factory reset wipes everything and returns the ZTE F670 to its out-of-box state.

Method 1 – Software Reset:

  1. Log in to the web GUI.
  2. Go to Management > Backup & Restore (or Reset).
  3. Click Restore Factory Defaults.

Method 2 – Hardware Pinhole Reset:

  1. Keep the device powered on.
  2. Locate the small Reset pinhole on the back panel (next to USB or power port).
  3. Use a paperclip or SIM ejector tool to press and hold the button.
  4. Hold for 10–15 seconds until all LEDs flash simultaneously, then release.
  5. The router will reboot. After 2 minutes, the default settings (IP 192.168.1.1, user admin/admin) are restored.

Warning: A factory reset will delete your Wi-Fi name, port forwarding rules, and ISP credentials. However, most ISPs use auto-provisioning (TR-069), so the device will re-download settings from the ISP within 5 minutes.
