5. Risk Assessment and Troubleshooting

Upgrading firmware always carries inherent risks.

Bricking Risk: Installing firmware meant for a different model (e.g., flashing NanoStation firmware on a Rocket) will render the device unusable. Always double-check the filename against the hardware label.
Configuration Incompatibility: Occasionally, a new firmware version changes the syntax of configuration files. If the device fails to boot properly, a factory reset may be required, followed by manual reconfiguration or uploading a backup file (if compatible).
Network Downtime: For critical infrastructure, upgrades should be performed during designated maintenance windows to minimize the impact of connectivity loss.
