RUT955 stops answering

We have a RUT955 that works fine after reboot but within 24h it starts responding with:

RunCmd: gsmctl --sms --send “TheNumber MyMessage”
Sms send failed. Error: [gsmctl_send_sms:20] error: ERROR: Request timed out

Checking System log it states “request reached timeout”.

Internal website is very slow at certain pages like Mobile Utilities and Download Logs.
Testing to send message also very slow but returns “Message sent”. Logs states “request reached timeout” but only some are actual sent but with a long delay (several minutes later).

Some screenshots on current status when acting bad included.

Reboot solves the problem.

Hello,

From the logs, it seems like the internal modem of the RUT955 stops responding. This could indicate a hardware failure, however, it’s too early to say if this is the case here.
In the firmware page, could you check if there is an update available for the internal modem? This might help with the issue.
Another thing you could try is factory resetting the device, as this would mitigate any issues caused by the configuration.
Finally, perhaps you have a different SIM card to test in this device to check if the issue reoccurs?

Best regards,
