RUTM54 - Modem update

Networking Solutions Question
1

Hello,

The RUTM54 has a Telit FN990A28 modem, and under “System > Firmware > Update Firmware > Modem Update” it shows that the modem version is “M0R.100005 / 45.00.105_A0R.001056_P0R.000566_0_ERROR”, and that there is no available firmware update for the modem.

On another hand, a new firmware (M0R.100006 / 45.00.106_A0R.001062_P0R.001503) is available on the Telit website (since 2026-01-25, based on the release notes).

Being in contact with an operator, they told me that they got a RUTM_R_00.07.16.1 SVN15 firmware, which matches with the modem update release notes (SVN Updated to ‘15’). That FW fixes some “Network Slicing” issues.

  • When will this modem update be available through the RUTM54 web interface?
  • Is there another way to update it? How?
    • There’s no modem_update package for the RUTM54…
  • Is there any reason and/or blocking points that would prevent to update the Telit modem to the newest FW for the RUTM54?

Thank you,
Jerome

Hello,

Modem firmware updates are performed only after the current issue has been identified and assessed, and it has been determined that a modem update is necessary to resolve it. Such updates require confirmation from our Support team before proceeding.

Thank you for your understanding.

Best regards,
