Hello,
I have a RTU240 running in Portugal with a SIM card. The most of the time it works well. But something randomly it looses the LTE connection and is not able to establish it again. Or only after a while. Today I wait about 30min with trying to reconnect, power off the modem, change LTE band to manual... No luck. Then I switched the SIM card to my HUAWAI portable modem and directly got internet connection back. This happend already several times. I thought it was better with new firmware RUT2_R_00.07.04.2 but also with that it happend again.
In the log the " Data connection state" was connected but the SINR showed "no signal"
I wonder how because the antenna and everything from the modem should have much better hardware and signal strength then my portable HUAWAI.
Are there any settings I can do within the modem to solve this disconnection issue?
Best regards,
Sebastian
