The ZTE ZXHN F670 is a high-performance Gigabit Premium Triple-Play G-PON gateway. Known for its dual-band Wi-Fi and robust fiber connectivity, it is a staple for many Internet Service Providers (ISPs) globally.

Hardware Overview and LED Indicators ZTE F670 — Technical Overview and Operational Guide

1. Disable WPS – Go to WLAN > WPS Settings > Disable. WPS has known brute-force vulnerabilities.
2. Disable remote management – Go to Management > Access Control > Set “WAN Access” to Disable. This prevents anyone from logging into your router from the internet.
3. Update firmware – Go to Management > Firmware Upgrade. If no update shows, don’t manually upload unless your ISP provides a file – wrong firmware bricks the device.
4. Hide SSID (optional) – Under WLAN > SSID Settings, uncheck “Broadcast SSID”. This hides your network from casual scans (but determined hackers can still find it).
