RUTX12 sporadically reboots after FW upgrade to RUTX_R_00.07.07

After I’ve upgraded FW of my RUTX12 to v RUTX_R_00.07.07.1, it started to reboot sporadically. Same holds with the version RUTX_R_00.07.07.2 as well. I use the router couple of years already and it’s the first time I’ve started seeing “Device startup after unexpected shutdown” system event in its event log. I’m pretty sure (200%) that the power is perfect there, I even additionally tried it with BAT120, same result. No device overheating or something like that. Purely FW stuff. Here is my system event log after upgrade to RUTX_R_00.07.07.1:

Do you usually ‚Keep Settings‘ when upgrading over the years as you said?
If so, it would be worth taking a backup on 07.07.2, set the box back to factory settings and either re-configure or restore backup (important: same box, same firmware version it must be!)
If your config is not too complex, just invest a few minutes in re-configuring by hand.

If you ‚Keep Settings‘ over the years you also keep the waste and don’t get changes in the default config made by Teltonika.

You want to give it a try?

I see there is a new FW released, with a “fixed config when upgrading from older firmware with keep settings” in release notes, 07.07.3. I’ll try this one first. If it will not help, then I’ll try to reset with clean settings and then reconfigure.

Good plan.
Let us know how it went!

I tried 07.07.3 and it didn’t help. I’ve got already “Device startup after unexpected shutdown” 2 times since FW upgrade. So now I’ve just tried backup of 07.07.3, then factory reset, then backup restoration. Let’s see how it goes.

Hello dshoot,

In order for us to be able to troubleshoot the root cause of the issue, we will need a troubleshoot file, but as the device is unexpectedly rebooting, we will need to save these troubleshoot files in Flash memory.

In order to save it into flash memory, login to your WebUI → navigate to System → Maintenance → Troubleshoot → " Logging Settings" section, there you will see “Save log in” option and choose “Flash memory”.

As the troubleshoot file will not be accessible that easily, I would want to make a remote session, where we could access the troubleshoot file and see what is the cause of the issue.

For further communication I have sent you a Hubspot instructions to your e-mail, check your inbox and there refer to further steps, your ticket ID will be 6460.

Kindly waiting for your reply,
DziugasS

Upgrade to 07.07.3, then backup, then factory reset, then backup restoration didn’t hep either. I’ve got one more ‘Device startup after unexpected shutdown’ in 4 days after that. I followed your instructions from email for the ticket 6460.

Hello,

Thank you for providing the troubleshoot file.

I see that the wireless interface is spamming error messages, which seems to shutdown the device.

ath10k_ahb a800000.wifi: Invalid VHT mcs 15 peer stats

There is plenty of these logs, after which the IPv4 connectivity starts to fail. Once the logs are flooded, the device shutdowns and reboots. I have tried uploading the wireless settings that you were using and my router started generating the same logs, which is why I think you need to change the settings of your wireless network.

By testing out some configuration changes, I noticed that once I have disabled Short Preamble, the logs stopped generating. Could you try disabling this option and then testing it out and see how it goes? Go to your router’s WebUI Network → Wireless → SSIDs → Edit the interface and choose Advanced Settings and disable Short Preamble

Do the same on both SSIDs and test it out and see if your device shutdowns unexpectedly.

Let me know how it goes,
DziugasS

Thanks!
I configured Wi-Fi as you suggested. Let’s see how it will work now.

I tried this Wi-Fi configuration and it didn’t help. I have 2 more sporadic restarts in logs after that. It seems that the only option to try which is still left is factory reset and then manual reconfiguration. Otherwise I can send you one more fresh troubleshoot file if needed. Should I send new one to you?

Hello Dshoot,

I have contacted you via hubspot once again, where I have provided a more private solution, please check your inbox and continue the conversation there.

In the meantime have a nice day,
DziugasS

Thanks! I decided to switch directly to the newest 07.08. I made a reset and reconfigured all manually from scratch after switching to 07.08. Hopefully it will work.

Hello Dshoot,

Let me know how it goes and if any issues arise with unexpected reboots, please generate a troubleshoot file and provide it via hubspot, so I can look into the issue further.

Best regards,
DziugasS
