Internal modem is unreachable

Hello teltonika
I have rut955 device which has error of internal modem is unreachable
I just try to reboot loader and update latest firmware but still fail to resolve problem.

What could be its cause and how to resolve it


From your description, it seems like the issue is hardware-related. Assuming that the device is still under warranty, I would suggest contacting your designated sales manager or the reseller from whom you have purchased the device to initiate the RMA procedure.

Kind Regards,
