I’m experiencing an issue with my TRB500 where the LTE band B3 is lost after some time and doesn’t reconnect automatically. Restarting the connection in the settings doesn’t help either; the device always requires a full reboot.
Here you can see how it normally looks:
The LTE bands B3 and B20, as well as the 5G band N1, are connected with very good quality.
Apologies for a delayed response and thank you for bringing this issue to our attention.
Could you try, if not already done, setting up manual band selection for these three bands (B3, B20, N1)? To do this, navigate to Network → Mobile → Connection, and configure the band selection manually to see if the issue persists.
To further troubleshoot this issue, could you provide a screenshot of the Events Log (accessible via System → Maintenance → Events Log) when the band disconnection reoccurs?
Additionally, we always recommend ensuring that your device’s firmware is updated to the latest available version.
Let me know if you need further assistance or if the issue persists so we can dive deeper into troubleshooting.
I have already tried locking the frequency bands, but unfortunately without success. I also set up a scheduled reboot for 3:30 AM to restart the device. Unfortunately, this hasn’t yielded long-term results either. In the event log (see attached image), there don’t appear to be any irregularities. The device performs the reboot as planned, but less than five hours later, Band B3 is already gone again.
Yesterday, the new firmware for the device was released, and I have already installed it. After the reboot, all connections are back as they should be (see attached image).
Is there any way to enable extended logging or something that could indicate the root cause of why the connection is being lost? It’s unlikely to be the provider’s fault because as soon as I restart, everything works perfectly again – at least for a few hours.
To identify the precise root cause of the band disconnection, further troubleshooting will be needed.
