Hello,
I recently upgraded a RUT240 from 1.12.2 to 1.14. I noticed that the device was not able to establish a mobile connection. Its mobile connection was "Disconnected", Connection Type "NOSERVICE".
The device was replaced with a spare device. I downgraded the Firmware back to 1.12.2. The mobile connection started working again. After that I upgraded to 1.12.3 successfully, mobile worked. When I upgraded from 1.12.3 to 1.13 the mobile connection stopped working. I use a Deutsche Telekom "Business Smart Connect Trible SIM", all settings default. How can I fix the mobile connection?
