Hi,
Our RUT955 reboots regularly (once or twice a day) without giving any errors. The event log just shows the wifi devices reconnecting and the mobile internet being joined.
It is using the supplied power supply, and that power supply is plugged into a UPS, so the power should be as good as can be.
There is nothing plugged into the USB port.
It is running the latest firmware (RUT9_R_00.07.04.5)
Please could you advise how to diagnose this fault?
Hello,
Did you notice any particular circumstances, when the reboot occurs, does it happen randomly or with a certain periodicity?
Does your router have any custom configurations or additional packages installed?
Could you log in to the device‘s WebUI and check if there are no running instances in Services → Auto Reboot → Ping/Wget Reboot and Services → Auto Reboot → Reboot Scheduler pages?
Could you login to the router via SSH and provide the output of the command:
Could you tell, whether the firmware update to 7.4.5 performed with keeping the configuration settings from previous versions? If that is the case, did you try resetting the router to factory default settings?
Best regards,
Hi! Thank you so much for your reply. I’ve just performed a factory reset (holding down the reset button for the right amount of time). I’ve just updated the admin password and WiFi SSID/password and I’ll leave the rest alone for now to see if that resolves it. Will report back in a day or so (or sooner if it keeps resetting) and shall provide the df -h output then.
Thanks again!
Hi,
Quick update - I performed a factory reset of the device and that seems to have restored stability.
Would it be worth adding this as a recommended step to any firmware upgrade that might need it in the wiki?
Thanks again!
I replied too soon. Unfortunately it is still rebooting.
As requested, I can confirm that there are no custom configs or packages installed and no auto reboot schedules in place.
Here’s the df command as requested:
root@RUT955:~# df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 10.3M 10.3M 0 100% /rom
tmpfs 61.0M 204.0K 60.8M 0% /tmp
/dev/mtdblock6 3.4M 444.0K 2.9M 13% /overlay
overlayfs:/overlay 3.4M 444.0K 2.9M 13% /
tmpfs 512.0K 0 512.0K 0% /dev
/dev/mtdblock7 576.0K 404.0K 172.0K 70% /log
Does the above look as expected?
Edit: This df command was run immediately (well, within a minute or two) of the device crashing and rebooting itself.
Edit 2: (Missed the “no” off of the answer to whether custom configs are in place… to confirm - nothing custom is installed)
Hi,
As an update to anyone else who stumbles on this. I’ve found what might be at least part of the problem.
As our RUT955 moves about the place, we had to add “_nomap” to the end of the SSID, as per google’s guidance.
I removed this, and the device seems to crash less often.
The issue seems to be with SSIDs that have an underscore “_” in them.
Removing the “_nomap” is a workaround, as it’s reasonable to have ssids with underscores.
Hope this helps Teltonika find a way to fix this, and for other customers with similar issues to work around it until a fix is in place.
