Firmware is the operating system of your router. For a 4G device like the 4G630, updates often address specific issues such as signal stability, APN (Access Point Name) compatibility with different carriers, and security vulnerabilities. Ignoring these updates can lead to intermittent disconnections or potential exploits.
