Trouble shooting router crashes. Setting up crash logs


I'd like this topic to provide some general advice on trouble shooting router reboots. I couldn't find much material on this.

My router started to behave quite chimeric and reboots without apparent reason. I suspect it might be something HW related, but I am not sure. I just don't see any apparent triggers.

I couldn't find any logs older than since current boot. Is there a way to get some info on random crashes? Preferably without opening the case.

Start with the OpenWRT list of logging options...

What is the temperature of the router CPU? Overheating can cause similar issues.
