It has now happened many times across multiple versions of the OS so it's not an isolated incident.
I've been noticing that my hub goes offline on a regular basis, requiring a hard reboot. There seems to be nothing in the logs. No IP conflict, so I am not sure how to troubleshoot.
Any ideas?
Relevant (unhelpful) section of the logs:
14:51 is when I rebooted, and there has been lots of events since 21:37...
