Router stop working after uppgrade to RUT2M_R_00.07.23.6

Hi

My RUT241 routers have stop working after upgrade to RUT2M_R_00.07.23.6 after a week.

I have about 50st installed so this create big problem for me. I need to send service people to manual reboot routers…

SMS Reboot is not working to reboot the router.

I cant connect to the router to SSH or HTTPS.

The routers is still answer Ping but SNMP pluggin is not working.

I have disable and activate sim-card from the phone operator for activate ping reboot but this is not working and ping is stopping to work after this.
