Later firmware versions might introduce features like IP passthrough (bridge mode), improved VPN pass-through, or enhanced LED controls.
Beyond security, firmware updates bring tangible performance improvements. The 4G185 relies on cellular modem firmware to communicate with mobile network towers. Updates often refine the modem’s ability to hand off between towers, manage signal interference, and maintain a stable LTE connection. Users have reported that newer firmware versions reduce the incidence of dropped connections and improve average throughput, especially in fringe coverage areas. Additionally, updates may resolve bugs affecting the router’s DHCP server, Wi-Fi stability, or the management interface’s responsiveness.
