I am no expert but is it to do with this in the event log?
11:38:29, 30 Jun.
I've been having issues recently too. I noticed there was a firmware update last week. There are issues nearly every time they roll out Smart Hub firmware updates so I expect it's linked to that. I'd not had any issues for months prior to that.
I am still getting a disconnection roughly every 2-3 days always in the evening. Disconnects then immediately reboots/comes back up.
Any ideas folks for troubleshooting this?
