Sample quick checklist
- Verify Hardware Version: Ensure the firmware matches the exact Hardware Version (Ver: X.X) printed on the sticker of the modem.
- Stable Power Supply: Do not unplug the power cord during the update process. Using a UPS (Uninterruptible Power Supply) is recommended.
- Wired Connection: Perform the update via an Ethernet cable connected to a LAN port, rather than Wi-Fi, to prevent packet loss during file transfer.
- Backup Settings: Go to Management > Settings > Backup to download the current configuration file before updating, in case a factory reset is required afterward.
