Hi @Serena_C

Tech came out, he couldn't understand why it was doing it (funny enough it won't doing it today!) he checked over the connection couldn't see anything wrong, but he replaced the white cable from socket to router, and the isolator connection on the hub, and moved me on a diff tap in the cabinet to see if that sorts it, he said he will give me a ring on Monday to see how things go. he said he will get in contact with networks to see if any issues show their end as well. other than that nothing else to say, but will wait and see if things change.

Hi @Anonymous,


Thank you for getting back to us with an update on this.

It sounds like they've carried out a few steps to narrow down and eliminate the potential cause of the issue.

Be sure to let us know how the call back goes on Monday, and if the issues appear to persist following today's visit.

Thanks,

Just to update. i had 3 days of no issue, then come Sunday evening it started again... ignore line at 4pm that was me updating my router. also downstream and upstream stats seem to be higher then before after he changed a few things..

Well there's definitely a problem!

I'd advise copying the data from the actual log page into a spreadsheet (I think the log only holds the last 20 entries (which is poor))

I'd do it hourly and remove the duplicates

Then you can show the T3 timeouts for a period of a few days - as we can see - it is an intermittent issue that when an engineer turns up - can't really fix as nothing is wrong at that time.

As a thought, does the issue happen when it is raining? - COuld be water getting into part of the circuit and causing an issue!

Hi StormW4tch3r,

 

I'm sorry to see you're experiencing some issues with the connection again. 

 

I've had a look and been through diagnostics and there are quite a few of the hubs levels showing out of specification, this will need an engineer visit.

 

I've booked this in, and you can view the time and date of the appointment via your online account here

Hi @Alex_RM

Thanks for another tech visit book, but the issue is, that not going to sort the underlining issue I was having in the first place which still hasn't been resolved, even with the connection put right it will still show, as stats were fine before tech came out.

 

@lotharmat as for your connect, this issue doesn't do it when it's raining or not, tech has check every point and said there no issue or so he says. t3 don't go up when this happens, it may got up 1 or 2 that's it

Hi StormW4tch3r,

 

Just to clarify this wouldn't be the same technician that attended last time, he would be different.

Update on today tech visit, couldn't see anything wrong with connection (again) said everything was in range, spoke about my issue, did a few checks, as my white cable to hub and isolator was already replaced he won't going to do that, be requested a re-pull which was done about 5 hours after he left, he also has a job to come back on Thursday, to see how things are going, but said to say after a cable re-pull issue is on going still, igore 10am packet loss that was him checking things, no idea what the 2pm was issue maybe? 3pm till 3:30pm was then doing a re-pull, just before 4pm was me restarting hub to clear stats so it was fresh due to cable re-pull, other packet loss is the issue i'm having. So now everything from my house to cabinet has been replace to me looks like a VM issue somewhere.

Hi @Anonymous,

 

Thank you for getting back to me on this issue and for updating us on your appointment.

 

It is really helpful that you identified all the drop outs on your BQM chart. In this case, I would advise you monitor your connection over the next 24 hours to ensure that this technician visit has helped.

 

Please get back to us then and we'll see what else we can do to have this issue resolved for you.

 

Thanks!
