Rut906 Keeps forgetting Sim

Hello,

I have a problem with one of my RUT906’s. The problem is that the router would sometimes just lose all connection and the status LED would flash red and green, indicating no sim or a bad sim pin. The thing is the sim card has no pin. Sometimes if we do a power cycle it would work again, but then 2-3 days later it would get the same error.

Hello,

Thank you for your inquiry.

To help understand and begin troubleshooting what might cause this issue, could you please confirm the following:

  • Does the identical issue occur if you test with a different SIM card?
  • Did this behavior begin only recently, perhaps after a configuration change or firmware upgrade?
  • When the problem occurs, does restarting just the mobile connection resolve it, or does it only recover after a full hard reboot/power cycle?
  • What firmware version is the device currently running?
  • Do you notice the connection drop following any pattern (e.g., always around the same time of day)?
  • Would it be possible to provide system logs (System → Maintenance → Troubleshoot page) whenever the issue replicates?

Best regards,

Hello,

Yes, we are using 4 routers on 1 site and all four of them are giving the same issues.

We have now tried connecting them to ethernet, but when we do that, it looks like the router just freezes. It won’t connect to mobile, and it won’t connect to ethernet. We then decided to try Wi-Fi, but we get the same issue. It seems that if the mobile connection isn’t working then nothing is working. I tested it with another router at our office, and I get the same issue.

I would reboot the router with an ethernet cable connected and no sim. I would then pick up the router and the ethernet’s ports would flash, but as soon as the mobile connection fails and the status led turns red then the ethernet stops working.

I have tested this on firmware version 7.16.3 up to 7.17.3.

I will get the trouble shooting file from the router I tested in the office.

Hello @ChrishLuies,

In this specific case, to troubleshoot and understand this matter effectively, we’ll need to continue the process privately, because sensitive/publicly unshareable information, such as the troubleshoot file, containing configs, logs, serial numbers, etc., needs to be collected.

You should find a support request form in the inbox of the email address you used for your forum registration. Kindly fill out the form, and please reference Ticket ID: 15556 when submitting it. Once the form is completed, we’ll contact you directly via email to investigate the issue in detail and help work towards a solution.

Best regards,
