Do not interrupt during reboot. | | Router reboots randomly post-update | Conflicting config from old firmware | Perform a factory reset (press reset for 10 sec). Reconfigure from scratch. | | LTE signal weaker after update | New firmware changed band priority | Manually select LTE bands (if UI allows) or contact ISP for rollback. | | Wi-Fi password rejected | Update reset NVRAM but not user settings | Hard reset via pinhole. Then re-enter credentials. | zte mf293n firmware
