Good morning, I have a problem with my TRB 140 gateway . after installing the firmware released in November ( 00.07.10.02) the connection to my mobile operator constantly disconnects. before the update no problem was highlighted. what can I do ?
As suggested by the support i installed the last version 7.13.3 but the situation doesn t change.
My operator is Wind. I did this simple test , i put the TRB sim in other modem Huawei and the connecction was stable and up. Many thanks

Hello,
Could you please let me know if you see any errors in the WebUI, such as “Internal modem unreachable”?
If so, please log in to the device via SSH/CLI (https://wiki.teltonika-networks.com/view/Command_Line_Interfaces_RutOS), execute the command lsusb, and share the output here.
Thank you.
Best regards,
hello,
i did the command LSUSB using CLI but without any output.
If i go in STATUS/NETWORK/MOBILE and i try to restart the connection i read a pop up with wrote: FAILED TO RESTART CONNECTION, MODEM NOT FOUND.
If i did the command LOGREAD the output is very long and it is no possible to paste on the windows.
The led signal show 3 led on and the 4G led blink

Hello,
I am experiencing the same issue, but with a Teltonika RUT241 instead of the TRB140.
The modem suddenly stopped working with my mobile operator (Wind). The SIM works perfectly on other devices (tested on an iPhone with a stable connection), so I have excluded problems with the SIM or the network coverage.
I am not sure if the issue is related to a firmware update, as I did not use the modem for a while before noticing the problem.
Additionally, I tested the RUT241 with an Iliad SIM, and it worked correctly without any changes to the settings. This suggests the modem is functional but there may be a compatibility issue with Wind.
When I try to restart the connection from the WebUI or CLI, I get the error message: “Failed to restart connection, modem not found.”
I read the discussion here and the symptoms match mine exactly.
Do you know if there is a firmware version that does not have this problem?
Thank you in advance for your support.
Best regards,
Alessandro
Good morning; in my case the problem occurred after a firmware update.
I don’t remember the version perfectly, but the last working one for the TRB 140 should be 07.10.01.
In my case, I only have coverage with Wind and if the issue is not resolved, unfortunately, I will have to change the modem.
We hope in the support.
Best Regards
Alessandro
Could you please try performing a hard reboot on your devices and check if the issue still persists?
Thank you!
