Anyone who have an idea why I loose mobile connection based on the eventlog?

Have you updated the device firmware and cellular modem firmware to the latest versions?

Are you using two cellular antennas?

Is the cellular signal strength good?

Hi, yes I am using two antennas.
Signal strength are good.
The firmware is from 2017, version 5.2.17.12

The latest WR21 firmware may be found here: wr21-8.3.1.2.zip
jeremym brings up a good point in regards to the module firmware.
What module do you have and what version is it at.
To determine what module you have here is a link that should help: https://www.digi.com/support/knowledge-base/how-to-determine-which-module-to-select-in-the-fla
In regards to the version, if you go to Administration – Execute a command, then enter ‘modemstat ?’ (without those tics). It should show you the module as well as the firmware version.
Because of all of the various versions of modules, it’s hard to give you a particular procedure.
I hope this makes sense.
