Hub3 rebooting

After persevering with numerous intermittent  hub reboots and calk to help desk, eventually engineer arrived.  No issus since 14th May but today 19th May another 2 reboots and when I look at the network log, the same T3 I critical errors logged just prior to the reboot.

 

VM had previously blamed my 3rd party wifi mesh setup but prior to the engineer visit I disconnected everything from hub and it rebooted that night.  After his visit it has been fine until today.

 

Any ideas?

Re: Hub3 rebooting

In most cases spontaneously rebooting hubs are not rebooting, but doing a full re-registration with VM's network gear.  And the usual reason for that is cable noise which can be intermittent.  I'll assume any power problems were addressed by the technician visit.  If you post the hub's status data for Downstream, Upstream and Network log (text, not screenshots) then we'll be able to comment.
