By default, V9.0 forces Bandsteering, combining 2.4 GHz and 5 GHz into one SSID. This frequently drops latency-sensitive devices (like gaming PCs or consoles) onto the slower 2.4 GHz band. Navigate to . Set Bandsteering to Off .

The ZTE F670L is a popular GPON Optical Network Terminal (ONT) widely deployed by Internet Service Providers (ISPs) for fiber-to-the-home (FTTH) deployments. While the hardware is robust, earlier firmware iterations occasionally suffered from uptime stability issues, colloquially referred to in technical circles as "TOP" (Time of Power/Uptime) failures.
