Hello,
How frequent are the disconnects? Could they be periodically initiated by your provider to update the the IP lease?
Would it be possible for you to test the card in a smartphone, to see if a similar behavior occurs?
The provided troubleshoot file shows only a couple of the first minutes of device operation, which by the end results in a successful mobile data connection.
Would it be possible to receive file after some more time, when the disconnect occurs?
Also, could you configure Auto reboot, to restart only the internal modem on the detection of disconnection, to check if that could be the solution?
Best regards,
