MG21 drops Cellular interface 6-7 seconds daily

[rsage_voda]

I have a MG21 that is running 1.11 firmware. I notice the following in the log.

Does  anyone know what is happening.

This unit was going offline regularly for long periods of time on the old firmware 1.9. Mobile coverage is good.

To me the graph you’ve provided looks clean with minimal packet loss.  When the dashboard reports a status change of the primacy uplink does the device go offline and the site loses connectivity?  Is this purely cosmetic?

[rsage_voda]

Unable to determine as its backup and doesn't get used unless the Primary fails which it doesn't. The site is a battery farm connected to the UK power grid so getting downtime to investigate is problematic.

Given that it is 6-7 seconds each day suggest to me a code is rather than a circuit issue

Or it could be that you get a maximum session of 24 hours from the carrier and the MG then establishes a new one?  The time seems to slip each day.  Try disconnecting it in the middle of the morning and see if the blips move to repeat at that time.
