OS Version: RUT Version: RUT9_R_00.07.03.4
Model: RUT955 but same issue was observed on a RUT950
My RUT955 continues to randomly connect and then disconnect from the carrier, Telstra causing a complete loss in network connection. The WAN port is not occupied and is intended to go unused. I am from Australia. The signal strength is extremely strong in this area and the status of the 4g network has been verified via another device on the same network in the same location. A high gain antenna has been attached which is new and known to be working. Different antennas have been tested all with the same result. The factory firmware was experiencing the same issues, upgrading the firmware continued to experience the same issues. After flashing it with the latest RUT955 firmware and erasing all custom settings it appeared as though the cellular connection became more stable however this was not the case and the issue persisted. I am experiencing the network working momentarily after restarting and then dropping out shortly after. I suspect this to be a firmware issue however I cannot prove this. It is either a firmware, config or hardware issue.
I have attached the trouble shoot file, the SIM card settings/status and the network events log for when it disconnected last. It was previously connected for several hours without serious issue. It had not reconnected for at least 3 hours after the last disconnection from the 4g network which I restored momentarily by rebooting the device.
The APN is correct and I have verified this with the carrier. I am at a loss for what could be causing this ridiculous issue.
