Disconnect radio chenal

Hello.
I used WP7502 legato version 18.06
Every 24 hours, the radio channel switches off. And the fall of the interface rmnet0.
i get log from modem.

I want to take away that something is happening with the system time.
Then time changes back.

What is happening with my modem?
What do messages from modemDaemon mean?

Seems related to another post, lets focus on the network drop in below

For time change, it may because network time update during re-attach.
You can find more info below or you can try disable this feature, but I guess instead should focus on why network reject happened…
