Random hub 3 reboots

[IanLodge]

I have been struggling with random Hub3 reboots now for a little over a month.  I can go a few days without a reboot then have 3 in an afternoon.  There is no pattern, no local VM work being carried out, no differences in load/connections.

Can someone take a look at the Status reports and see if anything is blindingly wrong.

Thanks In Advance.

PS

Trying here first as my interaction with the 'call centres in India' have been far from helpfull in the past

Yes there is a problem on the connection. Down channel 13 is awful. Low SNR and far too many Post RS errors - suggests that Noise is getting into the channel and overwhelming the Signal dropping the Ratio

Post up the 2 tables of Upstream data - but you are going to need a Tech visit to investigate

Try a pinhole reset and see if channel 13 magically repairs itself. If not call it in

Hello IanLodge

Sorry to hear of the Hub 3 issues but we appreciate you taking the time to raise this via the forums.

Were you able to complete the Hub pinhole reset? If so, did this resolve the issue at all?

Rob

[IanLodge]

I was able to complete a Pin Reset and still getting drop outs.

It is really strange as it can go a week without a drop and then 3 in an hour all whilst the usage has not changed.

Hi IanLodge, thanks for the reply. Can you do a reboot please as the hub has not been rebooted for 7 days. Once done please forget all devices and then connect only one to see if you are getting the same issue. Can you confirm if the hub is in an open area or is it in a cupboard? ^Chris
