SInce a few days, my 2yo RB4011 is randomly rebooting.
“router rebooted without proper shutdown, probably power outage” is in the logs, but there was no power outage, voltage is looking good at 23.7v
Devices on the same power outlet are all running fine, so no dip in the lines and such. Another PSU didn’t help.
I read people had it with 7,13.x firmwares, mine is running 7.14 now.
Support didn’t respond for a few days, so hope someone here has any idea on how to fix or at least can confirm the behavior i’m seeing is comming from 7.13+ releases.
For what it’s worth, I have an RB4011 (the US model) too, and it’s been on 7.14 for a while and now 7.14.1 and zero reboot issue here. So it’s unlikely to be a hardware-wide issue in that sense or I would also be affected..
I don’t use SMB, though - so yes, perhaps that’s where your issue lies (especially if both of you are using it, as seems to be the case…)
If you weren’t actually using SMB, perhaps try power the device from a suitable alternative/new power supply as a bad power supply is often to blame for a device that randomly reboots
Router has been up for over 24-hours now with SMB turned off. Seems like it might be working. Assume if you hear nothing more from me, disabling SMB resolved the issue.
Crashed after 5 days up on 7.13 … less frequent but appears to still have problems. Have since rolled back to 7.12. Too early to tell if it’s fixed it, has only been up for just over a day. But assume it has if I don’t post an update.
We have been seeing this on multiple sites as well.
Running ROS 7.14.2
Model: RB4011iGS+
Log states loss of power but its the only device rebooting and multiple devices are receiving power from the same source.
Do not hijack other topic, this is about RB4011.
I have dozen of ax devices, none do that problem, do not lost time, netinstall the device with 7.16.2, and if still have problem, do RMA.
The cause can be your wrong configuration that for some reason cause the reboot, or your particolar config that display a bug.
You do not post your config, on your topic, on the user forum for revision.
However it could be closely tight to the power problems. We do not know if there is or not a cable connection of two devices powered from different phases what could imply power spikes and reboots. I know that PSUs should do galvanic separation but who knows if it is true? Maybe different power loops bring that problems?
No, it’s “use the one with higher voltage”. Only if both supply voltages are almost exactly the same, then device will draw power from both (not necessarily exactly equal current).
Where concept of having twin supplies kicks in is if primary (with higher voltage) is failing … which can be expressed as (transient) voltage drop … when the secondary power adapter can cover the energy needs. But to determine if failing power adapter is actually the cause of problems, it’s easier to replace it with a known one (specced at similar voltage and at at least same amperage) and see if symptoms disappear.
