TRB140 stops communicating with RMS

NETWORKING SOLUTIONS

Hello,

I’m currently facing the issue that I have a TRB140 running at a customer, and after a few days it does not connect to the RMS anymore, but still has an internet connection.

The screenshot is from yesterday (Feb 6th) and the RMS sees activity until the 3rd. It also stopped communicating with the RMS on the 24th of January until it was restarted on the 30th. To reiterate, the device still works and has access to the internet.

Firmware is TRB1_R_00.07.07.3.

The same problem occurs on other TRB140s sometimes after turning the power off and on again. The device has internet access, but does not connect to the RMS.

Any idea why this is happening?

First of all, can you upgrade your router to the latest firmware version and see how it goes?
It is super difficult to troubleshoot on older versions…

I should add that the problem is usually fixed by turning the power off and on again.

I will update the firmware. Of course, the device will have to be restarted so that I can gain access. But that also means that the problem will be fixed temporarily.

Okay but let’s observe.
The changelog between your version and the latest one is h.u.g.e.

Hello,

Could you please confirm if you are still experiencing this issue?

Best regards,

It’s hard to say, this problem occurs very infrequently. But we haven’t had the issue since.

One of the gateways could not be updated: Could not upload firmware to this device. Check to see if the file you are trying to upload is correct and try again.

This message showed up yesterday - about one month after starting the update.

Hello,

Please let me know if you experience this disconnection issue again.
Additionally, to avoid rebooting the device, you can try reconnecting it by:

  • If you can access the device WebUI: Login to the WebUI, navigate to Cloud Solutions → RMS, and click “Connect”.
  • Or, you can send an SMS command to force reconnection: “rms_connect”. More information on sending SMS commands can be found here: SMS Utilities.

Regarding the update issue, could you please confirm the current firmware version on your device and the version you’re trying to update to?

Best regards,

The WebUI is not available when this problem occurs, but the SMS command might work. Thank you!

I tried to update from TRB1_R_00.07.07.3 to TRB1_R_00.07.12 (latest).

Hello,

Could you please confirm if you encounter the same error when trying to update to the latest 7.13.1 firmware?

Best regards,

The update to 7.13.1 completed successfully. However, the TRB does not reconnect to the RMS. I tried to send an SMS with “rms_connect”, but I received a nondescript error which I’m now investigating with our mobile service provider.

Hello,

Could you please also try sending the following messages:

<device_password> rms_off
<device_password> rms_on
<device_password> rms_connect

If this does not help, please send:

<device_password> rms_status

This will check the current status—please let me know what it shows.

Additionally, you can try sending:

<device_password> status

This will provide connection information from the gateway.

Please let me know the results, and if you need any further assistance!

Best regards,

Hello,

I’ve managed to send the messages you’ve provided. rms_connect and rms_off + rms_on + rms_connect (each with the device password) don’t change anything.

The response I get from <device_password> rms_status is:
Disconnected, Network is unreachable

And the response from <device_password> status is:
Router name - TRB140; WAN IP - NO_WAN_LINK; Data Connection state - Connected; Network type - LTE; Signal Strength - -64; New FW available - No;

Kind regards.

Hello,

It seems there is an issue with the device’s internet connection. I recommend checking the device’s WAN connection. Once the device has an active internet connection again, please try connecting it to RMS.

Please let me know how it goes.

Best regards,
