Slow upload speeds for a full month now
I'm currently on Volt M600 Fibre Broadband which usually gives me around 40mb up and for the last month or so my upload speeds have been terrible and sitting around 25% of what they should be, someti...

Hi Kreg 👋
Thank you for keeping us updated! So sorry to hear that you have still been experiencing these speed issues!
It does look as though the SNR outage has been extended to 06.11.23 at 1pm.
SNR (signal to noise ratio) is just a technical term for interference of the Broadband signal caused by noise which ingresses on to our network. It's a difficult problem to locate and diagnose because noise can ingress anywhere on the network. As a general rule it's normally caused by customer equipment e.g. loose connections or 3rd party equipment attached to our network. However it can also be attributable to local architecture, e.g street cabinets, cabling or at the origin of the signal which we call the Headend (servers/routing system). The only way to establish where the noise is originating is for the Network Techs to run a series of trace routes. Once found then the cause dictates the amount of work required and the time frame for resolution.
It also looks as though you have been in touch further since your last post and that an engineer appointment was booked. Hopefully this went well? Please let us know how you are getting on following any actions being taken by the engineer! We do hope this improves things, but keep us posted if you continue to have issues so we can provide further support or outage updates if needed.
Wishing you all the best! 🌞
Hi Molly, yeah we had an engineer out on Friday who swapped my Hub 3 for a Hub 5, all tests he done on the line were showing full speed capability and I was hitting 40mb most of Friday night and able to upload 9GB to YouTube in 35 mins or so. However, yesterday afternoon my uploads dropped to 5mb and this morning they're all over the place, ranging from 10-37mb and ~90 mins to upload the same amount of data so things are still very intermittent.
Samknows is also reporting varying speeds, sometimes the router upload is 17, sometimes it's 40.
I'm noticing a fair amount of T3 timeouts on channel 4 on my upstream and these are flagged as "critical" on my network log, not sure if this is related?

I set up a BQM and this is the results from yesterday/today.
and this is my upload this morning, these two tests are within minutes of each other:
Service Status phone number reported an eningeer in the area to fix a broadband and TV fault today and speeds have been flying all day so I assumed this issue was over as I was getting a solid 40mb upload on each test until around 6pm. However, it’s crawling once again and the service status is back to the intermittent issue I've been facing for weeks on end.
I'm getting really, really annoyed with this.
I appreciate it's a priority 4 but it's continually bumped down the list and I can't even speak to anyone regarding it. Whatsapp takes hours to be fed the same script and it takes days for a reply on the forums.
We've had engineers in the area for the last 2 days according to the service status website and absolutely nothing has changed.
The 6th November date has come and gone with no resolution which is now the 7th date I've had for this to be fixed with none of them actually happening. It's nigh on impossible to speak anyone about it either, I've still got around 12 months left of my contract but I don't think I'll be staying with Virgin after the length of time this has been ongoing.
When it works, it's incredible... when there's an issue, it's an absolute nightmare.
