Hello,
I will ask you to replicate the issue with the device losing connection, then without restarting the device, log into the WebUI, navigate to System → Administration → Troubleshoot, and generate a troubleshoot file. This file can be attached to your original question and will only be visible to Teltonika moderators.
As for the speed, there could be many reasons for such a drastic difference. More information can be found here. To summarize, phones have a much higher category LTE modem, which allows them to aggregate many bands. E.g. the newest Qualcomm X70 modem contains a Cat 22 modem with theoretical download speeds of 10Gbps.
However, higher speeds can definitely be achieved by the RUT241 by:
- Using an external directional antenna;
- Selecting a band with higher throughput;
- Select a better spot for the device;
Best regards,
