No data connection on RUTM09 and APN orangerun

Hi,

I recently acquired a RUTM09 modem and am trying to configure it with our Orange 5G connection.
When I first received it, everything was working properly. A notification popped up informing me that a firmware update was available (from RUTM_R_00.07.20.3_WEBUI to RUTM_R_00.07.22.1_WEBUI). I proceeded with the update using a file, but without preserving the settings (I hadn’t made any changes at that point). The update was applied successfully.

However, after this update, we could no longer establish a data connection. I’ve tried several troubleshooting steps:

  • Manually configuring the APN: APN = orangerun, Authentication = orange, Password = orange

  • Downloading and installing the APN database package

  • Manually selecting the operator code (64700) and the operator

  • Testing different SIM cards (all from the same operator)

  • Downgrading the firmware

None of these solutions worked. The modem connects, but no data is transmitted.

Do you have an another throubleshooting steps I could try ?
