Re: Upstream regularly drops close to 0Mbps on ethernet

Hello willypimpernel

Thanks for the updates and stats 

Happy to get an engineer out for you as a few of the downstream levels a just out

I will need to send you a private message to pass security 
If you can check the purple envelope top right of your screen that would be great 
Regards

Re: Upstream regularly drops close to 0Mbps on ethernet

After a couple of engineer visits and a total loss of service, I'm still experiencing dropouts.  These seem more severe, which is to be expected now the cable is flapping around outside the trunking?  Both engineers said the problems would be fixed by things other people were doing.  I'm not sure how to get this addressed?

Weirdly downstream power levels are now around 3 compared to 6 yesterday, but the engineer said that was within range

Re: Upstream regularly drops close to 0Mbps on ethernet

Hi @willypimpernel

Thanks for coming back to us. I am sorry it's not sorted. I've done some further checks and there's low SNR on two of the upstream channels. 

This is another tech visit so I shall PM you now to advise further.

Best,

Re: Upstream regularly drops close to 0Mbps on ethernet

Hi @willypimpernel

Thanks for your message but please don't send a PM unless we ask 🙂

How's the internet been since the message? No issues are showing for the checks ran so I am hoping it was just a temporary blip.

Best,

Re: Upstream regularly drops close to 0Mbps on ethernet

Sure thing, sorry.

Unfortunately there's no improvement.  The connection is dropping regularly, just as before.  Looks like a replacement router has not solved the problem, so I still think the issue is outside my house.

Here are the numbers since yesterday

Re: Upstream regularly drops close to 0Mbps on ethernet

Things seem much worse than before.  Dropouts are far more regular (several times an hour) and the numbers look much worse.  There are several million more post-rs errors on each channel compared to yesterday, and a bunch of T3 errors on the upstream.  

I'm no longer able to take video calls, which is a real problem as I work from home.  Is there any way to go back to how it was before?  That would at least keep me going until I can get a new provider installed.  I really don't want to switch because the speed is important to me, but speed is useless if I can't maintain a connection.

I really appreciate any help.

Re: Upstream regularly drops close to 0Mbps on ethernet

Hi @willypimpernel,

 

Sorry to hear you're having some issues with the service.

 

I've taken a look at the account and our system has identified errors on the broadband network for several days. This could be causing slow speeds or a degradation of service (pixelating/buffering whilst streaming). I am going to pop you a PM now so we can take a closer look into this.

Hope to hear from you soon.

Re: Upstream regularly drops close to 0Mbps on ethernet

Thanks for confirming the requested details via PM @willypimpernel

I've booked a technician for you to come out and have a look into the issue with your service. You can find confirmation of the visit via your
online account.

Please let me know if there are any problems with the date or time and I can look to reschedule this for you. In regards to the appointment there are some details you need to know about. There will be no charge for this visit unless:

•The technician diagnoses the faults as not being caused by our network/equipment
•The technician discovers that the fault or problem relates to your equipment
•The technician discovers that the fault or problem relates to any system that we are not responsible for

The technician will confirm during their visit if any of these instances apply, and if so, a £25 charge will be applied to your account.

 Please ensure there is someone over the age of 18 present at the time of the visit. If you need to change or cancel your appointment you can also do this online or via the
MyVM app by 4pm the day before the appointment.

If you do miss an agreed appointment for any reason, a £25 missed appointment charge will be applied to your account on the day of the appointment.

Let us know how the visit goes!
