Bad Latency Issues (With BQMs)

Apparently I should post my BQM here to see if "members can help" even though Virgin are the only ones able to fix their own cables. I've already had 2 engineers come out, had new wiring, new router, new ethernet cables and they both said the source of the problem was the cab, nothing to do with my home or router. Always experiencing constant fluctuation through out the whole day that is out of my control. 2 engineers both saying the same problem but no one tells the networking team to fix it...

Paying for 350MB Fibre (Average 380MB Up and 30MB Down when traffic is normal) this varies in the day sometimes only reaching 200/100MB. This has been happening since the start of covid, can also show the last 3 months of BQMs, here is the past 4 days, middle of the week and the weekend.

Re: Bad Latency Issues (With BQMs)

They all point to local over utilisation to me. One indeed for VM to sort out.

Re: Bad Latency Issues (With BQMs)

A local friend has the same problems at the exact same time. We have close to matching latencies, if I go to 100 he goes to 100. Baffles me how 2 engineers both say the networks need looking at and virgin refuse to send someone out

Re: Bad Latency Issues (With BQMs)

The fact that your VM neighbour gets the same tends to confirm it. 

Ttbomk there is additional cost and complexity for VM in addressing this issue and it rarely seems to be done quickly. 

You may wish to begin to explore alternative providers but do log a formal complaint via your online VM account.

Re: Bad Latency Issues (With BQMs)

Mate I've complained that much my complaints disappear online now. I've sent at least 10 complaints in the past 6 months and I've had answers to 2. One of them was when the engineer come out, the other was when they told me there was "work" being done but of course it wasn't fixed for the specified date.

Re: Bad Latency Issues (With BQMs)

Yikes you weren't kidding, with how bad that latency is, VM should've sorted this out ages ago. Things move very slowly at VM so don't expect a resolution for a good year or two judging by similar threads on here. But yes, Cardiffman281 is right, complain, give them chance to fix or go elsewhere if they can't.

Or maybe there's some really bad noise on the cables in the area? (assuming it's coax/hfc). What do your router stats show?

Re: Bad Latency Issues (With BQMs)

That is good news in a sense as you are likely now to be in a position to demand a deadlock letter and take it up with the arbitration service CISAS https://www.virginmedia.com/help/complaints

If you choose to you should ultimately be able to leave with no need to pay early leaving fees and possibly have some compensation too.

Because going to 100 is easy

Re: Bad Latency Issues (With BQMs)

They checked for noise too, the engineer himself said a couple of the channels needed tweaking but other then that it shouldn't be this bad especially on a Hub4. Is this the stats you were after?

Re: Bad Latency Issues (With BQMs)

Hey there @KC2000, thanks for the post and a warm welcome to the Virgin Media forums.

I'm sorry to hear about the issues you're having with the Virgin Media broadband.
From our end of the system, we can see that the upstream level is not where it needs to be and will require an engineer.
I will send you a private message to get this booked in - watch out for the purple envelope 🙂

Kind regards.
