Hi @edwins
Yes, for the moment, we recommend staying with your 7.1.0s045 Firmware. However, if you want to upgrade to 7.1.1, our engineering team will be able to help resolve the problem you are facing with “No SIM Detected” type messages.
However, in order for the engineers to help, please open a > Support < ticket, enable > Remote Assistance < and connect the SpeedFusion Engine to a Wired WAN (changing the Ethernet port from LAN to WAN first).
Thanks,
Steve
