EG12-EA Mikrotik Chateau LTE12 Modem control interface reset

Hello everyone,

on Mikrotik chateau LTE, the LTE modem is regularly reset. The LTE1 interface is no longer visible in the configuration tool. This happens even if only one band is selectioned (20 or 3) or when CA is used. This also seems to happen under heavy load. Tested with two SIM cards that work well on a Netgear router and on a Fairphone

Thanks in advance for your help !

Thanks for your query in Quectel forums.
Please check whether the module is restarted due to insufficient power supply, because the module will emit high power and consume high current when it is plugged into the network. If the power supply is insufficient and the current is insufficient, it is easy to restart the module. It is recommended to check the power supply of the module and check whether the VBAT of the module has voltage sag when the module is restarted
