Very Slow Upload Speed

Hi,

For the past week my download and upload speeds have fluctuated hugely.  My upload during the day is very slow, anywhere between 0.2Mbps and 1.2Mbps.  I'm trying to work from home and the upload is dropping conference calls etc and making it very difficult to work.  This is both on wired and wireless connections, I've complete a hard reset of the router etc.  I used the help messaging and the only response I got (after 24 hours) was to hard reset the router which I'd already done.  No further replies.

I've called VM 4 times, disconnected after 30+ minutes 3 times and finally got through to someone.  They told me I had received a speed upgrade and to complete another hard reset of my router.  I did say that I was dubious that this would resolve the issue but completed nonetheless.  Still the same issues during the day.  It's fine first thing this morning but I know that come 9am it will slow to a crawl again.

Is this a backend capacity issue within VM or a localised issue?  I'm in the Cambridge area.

Thanks

An engineer has checked and my power levels are still wrong despite the previous tech visit 3-4 weeks ago.  I've got another tech coming out on Friday who will also fix my landline (hopefully!).

Thanks for you reply!

So the engineer that was supposed to come out on Friday was cancelled. This was because the visit was raised against the issue I was having with my landline, this was resolved centrally as part of a wider issue. My visit was automatically cancelled by the system.

One of the forum team confirmed my power levels are still out last week but now I can't get hold of them to make me a new engineer appointment. Could someone from the forum team contact me to arrange another engineer visit?

Hi All,

I can't upload or join my team meetings. My MS Team meetings are usually dropped and can't talk online. I have recently moved to Virgin M500 deal to enjoy high speed but my upload speed is driving me crazy and disrupts my job a lot.!!! My download is fine and around 200mbs but my upload is around 0.3 mbs. It is not even 1mb. This morning, I had to use my hotspot to upload a doc. Can you please look at the network status below and tell me what I need to do. I am in N14 area.

Hi Keith,

I've seen you give some great help to people on these forums, I was wondering if it would be possible to do the same for me?

I'll give you a quick rundown if that's okay.

I used to be on the 200M package with Virgin Media and for a long time it was perfectly fine. 20Mbps upload worked when I streamed, uploaded files, etc. About a few months after the pandemic, my upload speed took hits for months which affected my hobbies and job. I was offered a free upgrade to the 300M after countless phonecalls and complaints. I was told that the upgraded package to the 300M one would solve my issue because I would have "more upload to work with" during peak hours. For a while this was true but once again, my upload can go from 36Mbps+ so single digits and it is again affecing my livelihood.

I am going to complain again but I urgnetly need some kind of fix outside of VM just admitting they have absolutely awful traffic management.

Kind Regards,

Dan

Also in N14, identical problems (refer to my previous posts) for the first time I have seen engineers in the proximity of the property today. Hoping for a solution soon, I have spent dozens of hours on this matter + weeks trying to communicate.

And another one.  ON the MB200 package, upload speeds used to  be 20MB on the dot, but now, fluctuates between 1MB and 2.5MB.

 

Tried every setting imaginable, from firmware uploads on PC, router, tweaking network settings (Ethernet), but something's changed and also unable to get any useful support.

And another here in HP6. 

My slow speed is to the minute, 0900-1900. Either side of those times, I see ~20Mbps. Between 0900 and 1900 I get 1-3Mbps. 

Yet, Virgin Media are adamant they're not traffic shaping at all. 🙄

I can run a speed test at 08.59 and get 20Mbps, then at 09.01 it'll hit the floor at 1-3Mbps.

https://twitter.com/adamlstr/status/1361995687148290050 My twitter exchange with Virgin Media is a similar 'bang head against wall' type of interaction. 

Hello adamlstr

Thanks for your post 

Apologies for the poor service 

Can you please set up a BQM and leave it for the next 48 hours 

Post the results in here and we can have a look at what is happening

BQM's appear to only monitor latency by measuring ping response. 

My ping is unaffected during these times, it remains 11-15ms. 

My upstream speed between the hours of 0900 and 1900 drops from 20Mbps to 2Mbps. It's appalling. 

Hi adamlstr

Would you like me tro arrange an engineers visit then to check things over
