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.
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 zte f670 manual
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.
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. ZTE F670 Manual: A Complete Guide to Setup,
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

7. Troubleshooting Common F670 Issues
Part 1: Hardware Overview – Know Your Device
Before diving into the software, understanding the physical ports and LEDs on the ZTE F670 is crucial. While there are variants (F670L, F670 V2, F670X), the core layout remains consistent.
The LEDs (Front Panel)
Understanding the light patterns helps diagnose issues instantly:
- Power: Solid green – ON. Off – No power.
- PON: Solid green – Registered with ISP. Blinking – Attempting handshake. Off – Fiber signal lost.
- LOS (Loss of Signal): Red blinking – Critical error. Fiber cable is damaged or unplugged.
- LAN (1-4): Solid/Slow blink – Connection active. Off – No device plugged in.
- TEL: Solid – VoIP line registered. Blinking – Phone in use.
- 2.4G / 5G: Solid – Wi-Fi radio enabled.
C. Changing the Local IP (To avoid conflicts)
- Go to Network > LAN > DHCP Server.
- Change IP Address from
192.168.1.1 to 192.168.2.1.
- Save. Your device will reboot. Login using the new IP.
B. Enabling Bridge Mode (Use your own router)
If you want to bypass the ZTE F670’s Wi-Fi and use a high-end router:
- Login as admin.
- Go to Network > Internet Connection.
- Find the default connection (e.g.,
TR069 or INTERNET).
- Change Connection Type from
Route to Bridge .
- Select your LAN port (e.g., LAN1) to bridge.
- Warning: Do not change the TR069 connection unless you want to lose remote ISP support.
- Save. Your ZTE will now act as a pure modem. Connect your router to LAN1.
