TRB246 BUG, SIM state not inserted when it is inserted

Hi, I have a TRB246 with connection issues.
Connection can work for days in a row, and then suddenly not anymore.
Same SIM is working in a RUT240 and a new SIM doesn’t solve it either.

How do I diagnose this?

Hello,

Thanks for reaching out!

Did you try factory reset to resolve the issue?

And also I need a bit more information. Can you please log in to CLI, username should be root and password is the one that you’re using to access WebUI.
May you please run logread | grep -i sim and share the output with me?

And also can you please share the gsmctl -A AT+CPIN? output of this command?

Hi,

I tried a factory reset before, it did not solve the issue.
And recently I rebooted to regain connection.

Hello,

From here everything seems normal.

Can you please upgrade the firmware to latest version and monitor for a couple of days?

Please let me know about the updates.

Hi,

I did a factory reset and I updated to the latest firmware, but I still have issues where I loose connection. When I go and look at the LED’s, signal is blinking and there is no connection to the cell tower.
I tried inserting the sim into slot 2 in case it is a hardware issue with the slot. But I did not get a connection and it seemed as if the device kept rebooting, at least that is what I think because I could see the LAN connection status from the TRB to my laptop continuously turning on and off.
After putting it back to SIM Slot1, I have connection again.
But this is not stable behavior.
What is wrong?

Here is a new output:


FYI, no network cable is inserted to the device, why do we see this info?

Hello,

Port speeds shouldn’t fluctuate that much. And if bootloader didn’t solve the issue,
there may be HW issue. I believe the warranty is still valid.
Would you kindly get in touch with your reseller to start the RMA procedure?
