Router crashing any diagnostic help?

Installing and Using OpenWrt
1

Hi.

I have a Nanopi R4S. I’ve had it about 6 months and I’m running latest build of openwrt.

My router crashes around once every 3 days or so, there isn’t like a set time or any form of logic to it. It just stops.

Dhcp stops giving out IP’s rebooting brings it straight back online.

I’m using high end major branded 32gb sd cards. I have tried an alternative card today but it’s already crashed once. It isn’t a major hassle hence I’ve put up with it for so long but I would love to know what’s going on with it.

I’m no expert in the openwrt field so any help would be appreciated

Can you still reach the device even when it is not handing out DHCP (via ssh or web interface)? Does it continue routing, or does that stop, too?

Please copy the output of the following commands and post it here using the "Preformatted text </> " button:

Either logging to an external syslog server in your lan -or at least keeping an ssh session with logread ; logread -f running- might provide some further insight into what's happening, I'd probably also keep htop running in a second ssh session as well.

So when it crashes the end results are different. Once when I didn’t have the family shouting at me I was able to set a static and log in. Everything seems rosy on the Nanopi.

Last night though when it crashed I could hit the login screen but that’s all would t log in felt like a full crash.

I will grab those results when home later. Thanks

I only have a smallish environment. Don’t have much in the way of excess hardware to leave running full time. Let alone the experience to decode the logs!! :joy:
