R7100LG GSM Modul defekt?
Hi, i get no more mobile connection with SIM card. SIM card is working in other modems. I take the router in factory reset but no result. Because it dont works i make a firmwareupgrade to V1.0.0....
Have you tried to revert the firmware to see if those settings start working again?

Hi DarranM,
Thank you for feedback and info.
I test it with the old firmware downgrade to V1.0.0.52 and same Error message while downgrade:
LTE MODEM UPGRADE FAILED
After reboot same situation: Adjusting for "Mobile Broadnad Settings" are grey and connot adusted.
