Zte F670 Manual

Before logging into the software, locate these physical components on your ZTE F670.

The ZTE F670 is a workhorse GPON ONT. It is not the fastest nor most feature-rich router (Wi-Fi 6 is absent, and the CPU can struggle with 20+ devices), but it is extremely stable for most home users with fiber up to 1 Gbps.

Should you replace it? If you need advanced QoS, VPN server, or mesh Wi-Fi, put the F670 in bridge mode and buy a separate router. If you just need internet, Netflix, and Zoom – the F670 is perfectly capable.

Last note: ISPs can push firmware updates that change the menu layout. If your GUI looks different from the steps above, look for similar wording: “WLAN” may be “Wireless”, “Port Forwarding” may be “Virtual Server”. When in doubt, search your exact firmware version (shown at the top of the GUI).
