- Improved Signal Stability: Better handling of cell tower handovers and reduced ping spikes.
- Band Locking Features: Many firmware versions unlock or improve the Band Locking menu (LTE B1/B3/B5/B7/B8/B20/B28/B38/B40/B41).
- Security Patches: Fixes for known vulnerabilities (e.g., default password bypass or remote access exploits).
- VoLTE/VoIP Enhancements: Better call continuity if you use the RJ11 phone port.
- UI Speed: The web interface (192.168.1.1) often becomes noticeably faster post-update.
Warning: A failed firmware update can brick your router (make it unusable). Always follow the official instructions provided by your Internet Service Provider (ISP), as they often customize the firmware.

- Visit the camera manufacturer’s official support/download page or the reseller page where you bought it.
