Connection Disconnects

[viperius]

Hi my network has been working fine and in the last 3 months it has started randomly disconnecting. This happens 4 or five time a day....

I have a hub 3 in modem mode

Unify Dream machine as my router.

All connected via ethernet.

I have extracted this from the logs. Seems when I am time traveling back to 1970 it causes some problems.

I see, is the service back on now? Is this via wireless or wired connection?

monitoring the wired connection.....out of the wall, into the back of the Hubv3 (in modem mode) into a Unify Dream Machine that have a number of switches, AP's and devices hanging off it.

Absolutely everything is fine on our end after checking through my tools, the BQM looks fine, the hub powerr/signal levels etc and absolutely nothing suggests any reasoning our equipment / network can be causing the disconnects. Can you run the BQM over a 7 day period and keep us updated with the logs please?

ok Guys, had a few disconnects over the weekend, can clearly see them on the graph.....thanks goodness I was beginning to think I was imagining it..

Happy for any insight. Dont think anyone on the NW was doing anything out of the ordinary....

Thank you for that information. Please do provide us with BQM after 7 days.

ok Chaps, BQM has been running for 7 days and I have had a few disconnects

Thursday 22nd - 1 disconnect

Friday 23rd - none

Saturday 24th - 2 disconnects

Sunday 25th - 2 disconnects

Monday 26th - none

Tuesday 27th - 2 disconnects

Wednesday 28th - None

Thursday 28th - 1 disconnect so far

They all happen at different times and nothing I am doing seems to cause it, least not anything I can see.

Thanks for coming back to us, I've been able to run a flow on your connection and have been advised of the following;

Our system has identified a very short term connectivity issue which may cause intermittent or performance related issues with the connection.

We believe that the issue is only impacting this connection but it'll only be a very short term issue and the connection will return to normal very soon.

As the issue is only impacting you connection, please check that all cables are connected securely. The issue that has been identified may be the result of a loose connecting cable.

Kindest regards,

Thanks for that. Just checked all the connection from the box to the back of the superhub. They all seem to be tight. I have given them a finger tight turn.

This has been working without interruption for the last 4 years and only recently started doing this.....

I shall keep monitoring the connection and let you know.

Thanks for your help

Thanks for coming back to us

Hopefully as the flow stated, this will clear up very soon and the connection will return to the expected standard

Our Forum Team will be on hand if you need any further assistance moving forward

Kindest regards,

Morning. its been a couple of weeks now and I have left the BQM running.

Good news is that I have weeks worth of data

Bad news is that it is still doing the dropping thing.

As per previous suggestion I have checked the connections to make sure they are nice and snug. I have even been noting what I have been doing when the connection drops to see if there is anything funny happening...it seem to be totally random though it is hard to see what some of the smart devices are doing but if they were doing weird stuff then other people might be having the same problem.
