Max BR1 mini cellular disconnect in Sim slot A

Hi I am trying to figure out why my cellular will disconnect every couple hours in the sim slot. Is there any fix for this?

What does the event log say?

Time synchronization failed then Cellular Disconnected from Sim Slot A


Time synchronization failed mostly related to the time sync packets sent not getting reply. It’s indicate that WAN connection for time sync traffics maybe having issue. If that is the cellular WAN and follow by the disconnection that may related to the cellular connection having issue.

May i know how long the cellular WAN reconnect back ? Can you provide the detail Event logs for the disconnection ? May need to check the frequency happen for the issue and repeatable after sometimes ?
