Hello,
I was not able to replicate your issue, the device responded to SMS after update via message.
Could you share the command you send to the device?
Could you login to device via SSH, execute logread -f command, then send SMS and see, if any messages are generated in the terminal regarding the event?
If you have updated firmware with Keep settings enabled, SMS not working may be due to the gap between firmware releases and possible migration issues.
I would like you to check, whether a device reset to factory default settings (login to the WebUI, navigate to System -> Backup -> Restore default settings) does solve the issue and SMS are received?
Otherwise, it would be helpful if you could provide a couple of troubleshoot files from your device:
- One with some older working firmware, generated after sending a couple of SMS to the router.
- Another, after update via SMS to 7.03.4, also generated after sending a couple of SMS to the router.
To generate the file, access router'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. Generated files can be attached by editing your original question.
Best regards,
