Vigor 2865ax debug error was created by xane
Hi, new user here.

I've had the router running for a while and it has not shown any issues, but I noticed that the uptime on the dashboard was a lot less than expected, so I checked the debug and it showed a firmware error, there was no timestamp so I am not sure if it correlates with the uptime.

Should I be concerned about this?

I noticed my version is 4.3.1_BT and the reported error has current version 4.3.1_RC7, so could this be an old error? If so is there anything I can do to see what caused the restart if not an error?

I've only just enabled the syslog on the console, so I can only see back a short time.

Please update to 4.3.2.1 firmware to see if that helps. Beyond that, if your wireless security is set to mixed WPA2/WPA3, try either WPA3/SAE only or WPA2/PSK only to see if that helps.
Please do get in touch with support if you find there are specific settings or clients that cause the router to be unstable, that can often be resolved with new firmware.
