I have RUT240 which has been running now for around 4 weeks using 4G connection. I update the FW in November, cannot remember exact version. I have enabled internet monitoring with automatic reboot and automatic SMS to inform me about reboot.
Since today RUT240 has lost internet connection, I can receive Status SMS which states that RUT240 is connected to LTE network, signal is ok but the WAN IP shows "-" instead of IP address from operator so no internet access. I have also sent reboot SMS but connection is not recovered. Is there some additional trick to be applied remotely?
