RUTM52 randomly disconnecting both modems

Following firmware and modem updates - RG520N - Modem Firmware , unfortunately we keep observing random disconnects on both modems.

The modem is powered via POE, BAT120 and an original powersupply - therefore I do not suspect that it is a power fluctuation issue.

A phone with a sim card roaming on the same network as modem1, stays connected throughout with no issues.

Restarting the connection does not fix the issue, rebooting the modem does.

Would appreciate support.

anyone else experienced this issue?

Greetings,

Apologies for the delayed response.

Please have a look at the following topic and update the modem firmware according to the provided instructions: Known Issue With RG520NEBD Modem Firmware (Update Required)

If updating the modem firmware does not resolve the issue, please let me know.

And as a temporary fix, you can configure a Ping Reboot on the device. This will automatically reboot the device after a data disconnect, so manual reboots are no longer necessary. More information can be found here: RUTM52 Maintenance - Teltonika Networks Wiki
