Hi I have a pc router with OpenWrt 21.02.2 and from time to time the router goes into a loop where I get disconnected from the LAN and WAN, so the only way I regain connection is to power off and on. But I can't find the logs and don't know where to start. The only thing I have is the following picture showing the loop.
If anyone can give me a hint on what to do next, I will be grateful.
v21 is EOL, upgrade.
Ok, I re-install and move to version 23.5.3 and I'm having the same problem. I test the same version in a commercial router and I don't have any problem. So I thing it's hardware relate. I test the ram and no problem.
Since you have on a computer, write the log to disk, to be able to see the crashed log, after a reboot.
Let's have a look at your config to make sure there's nothing obviously wrong:
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
First, I can't connect using ssh since no LAN connection is possible, but on the other side I don't have a monitor and keyboard.
So here are the files ask, and some logs I can acquire while having the problem, and I'm starting to believe the problem is related to ddns script, although I'm not sure.

Remove these, then restart and try again.
Can I ask why? I use the first 2 to access my servers, the last one was for a test.

Yes, I already disable the last one. thanks
After disabling the ddns service, the problem persists. My new theory: it has something to do with my download volume? I haven't got any problem for the last two weeks, today I downloaded two torrents and the problem came back.
