Our company has a TRB500 router and it works fine indoor (connected to indoor 4G/5G distributed antenna system), but on a location where there is less signal (2 out of 3 bars), the router keeps rebooting or the 4 and 5G lights keep flashing together.
Sometimes it has connection for some minutes, after that it starts rebooting again.
Tried another sim card but that did not help.
Entered manually APN settings for KPN (Netherlands), but that also did not help.
What can be the reason?
Please update to the latest firmware, then in the same firmware menu check if there is an update available for the internal modem (not the device itself). If there is, please ensure a stable connection, and update the internal modem. This update addresses issues with KPN 5G network.
Let me know if that helps.
How can I check if there is an update for the modem? It just lists the current version:
Where can I find modem firmware for download?
Hello @AdeG, I have similar problems, have you found a solution?
@bradojev did you have a suggestion?
Please post the modem firmware of your device (can be found in Status → System), as well as your operator and the 5G / LTE bands the device is connecting to. Thank you.
We have sent the TRB500 to Teltonika and received a new router from them.
But I haven’t tested it yet.
Let me know if it shows the same behavior.
If you’re in contact with one of our sales managers, I’d recommend inquiring about this issue via them, as we will be able to establish a private communication channel in order to troubleshoot the issue further.
