We have a number of TRB141's with a unit attached to it using DHCP. These units regularly loses internet connectivity, and a couple of days ago it happened once again for 5 units spread out all over the country on 5 different TRB141's within a few seconds.

The TRB's are accessible but the units behind them never come back up before we reboot them.

Can You see if something happened at that specific time and maybe help us regain the connections ?

Hello,

It would be helpful, if you could provide troubleshoot files from a couple of devices, by attaching them to your question. Please, wait till the issue replicates, then access device's WebUI, go to System -> Administration -> Troubleshoot section and download troubleshoot file from there. The logs in the file might provide more insight into the issue.

Attached files are private and visible only to Teltonika Moderators.

Best regards,

I added a troubleshoot file and below are the times that they lost connection: (DEV1302843 is the one from the file)

Hello,

  

The troubleshoot file seems to be from a TRB140, not TRB141, could you verify that all of the devices are TRB140s and all have LAN devices connected using Ethernet?

If yes, then could you try running this command:

ethtool -s eth0 duplex half speed 100 autoneg off

On one of the devices that are experiencing issues and check is the issue reappears?

If it does reappear, perhaps it would be possible to set the device to NAT mode to check is the issue reappears? DMZ can be set up to forward all of the traffic to the LAN device.

Sorry, of course they are all TRB140.

One came back up a couple of days ago by itself. I wanted to upload the logfile from the TRB140 but it is not online on RMS. I have activated a credit on it and we can access the units attached to it.

Can You look into why it is not coming online in RMS ?

Hello,

Apologies for the late reply.

Are you still experiencing issues with your devices in RMS?

Yes, I have just uploaded the troubleshoot file for a TRB140 unit where the unit behind it lost connection and came online again by itself almost a month later. Offline 18. April 02:09:20 and online 15. May 00:04:05

RMS has recently underwent multiple updates to improve stability and load distribution to avoid similar issues. Hopefully, this will help improve connection to RMS quality in the future.

If you still have devices offline, could you try reinitiating connection to RMS by sending SMS to the device with the following syntax:

  • <device_password> rms_connect

Replace <device_password> with the password used to login to router's WebUI.

If physical access to the devices is possible, the following can be attempted: login to the device via SSH and execute the following command:

  • /etc/init.d/rms_mqtt restart

Lastly, could you login to the device's WebUI Services -> Cloud solutions -> RMS page and check, if there is a Connect button? If it is, press it, otherwise unregister device from RMS and re-add it again.

Best regards
