Very slow upload and high packet loss

[coffeym]

For the last couple of days I am having huge packet loss, very slow upload speeds, and high latency. My BQM shows this clearly. Also, my upstream modulation looks wrong to me. 

Hub details to follow. Please can you book me an engineer? I’ve done all the usual things like resetting etc. Thanks.

Upstream power is too low!

I'd say VM need to send a tech to investigate.

Do you have any attenuators fitted?

[coffeym]

Hi, yes I do. I had an engineer out not long ago about downstream power issues. He said the upstream power levels above were OK for an FTTP connection (which I have, rather than HFC).

[coffeym]

The problem appears to have solved itself…no need for an engineer after all I think.

[Andrew-G]

Keep an eye on the hub status data.  Maybe it was an area problem that has been fixed, but the live BQM shows that on Saturday the problems did not start until 12pm.  I'm pretty confident that it isn't anything to do with network congestion, but it could be a noise fault that only becomes apparent when the network is busier, and as @lotharmat says yesterday's data points to an upstream problem.

Hi coffeym, thanks for getting in touch.

Sorry to hear about the issues you've had with your broadband.

I've taken a look into this today using your forum details and can confirm there's an issue with the signal levels that will require the attention of an engineer.

I'll get in touch via PM so we can get that arranged for you, just look out for the purple envelope.

Thanks for getting back to me coffeym. You will find confirmation of the booking via your online account (virg.in/myVM) and can reschedule from there if required.

Please keep us posted with how the visit goes, or let us know if there's anything else we can help with.

Tom
