Disconnects and low Upload speed.

Joining in

Hi just wanted to have someone check on my connection had major issues last year that was sorted with a Hub 5. However the last few months I've been getting disconnected every few days and my upload speed is around 23Mbs when it should be 100Mbs.

Would appreciate if someone could look into my connection and get back to me or book an engineer if needed please?

With only 5x 3.0 DOCSIS Upstream channels, reaching 104Mb/s is at the limits of what might be possible.

Check the VM Hub's Configuration Tab,
does it show the Upstream Max Traffic Rate as being set at 55 Mb/s or 110Mb/s.

Use the link below to speed test the Hub...

Once the test begins click on: Run full test to see Upload speed / Jitter  / Latency / Packet loss.

Do share a screen shot of the results.

Thanks for the response did that help you? As for the speedtest that link wouldn't work I will try on PC later on but here is one from I definitely should be on the 100Mbs package. 



 the second photo is a wired connection through an Xbox Series X use to always be like 98Mbs till last month and the drops started.

Hi @StealthDavid 👋

Welcome to our Community Forums and thanks for your post. 

Sorry to hear you've been experiencing issues with your service. 

I have ran some tests for you and our system has identified a short-term connectivity issue which may cause intermittent or performance related issues with your connection.

In the vast majority of cases, these types of issues are resolved after 24 hours.

We haven't identified any other issues that would impact your connection and we believe that it'll only be a very short term issue and your connection will return to normal very soon.

Our network can sometimes be susceptible to the occasional blip. These can be caused be network fixes happening in the area or new customers being installed. 

In the meantime, please can you check that all the white cables are connected securely to the Hub, any TV boxes, splitters and the wall socket.

Please monitor your connection and if the issue persists after 24 hours, let me know and we will arrange a technician visit.

Gave it a bit longer than you said unfortunately still bad had two hard crashes today alone. If you can't see anything that will get sorted on your end then I guess we'll have to do technician?

Hi StealthDavid, 

Thanks for coming back and updating us on this. 

Checking things today, it looks as though the hub is having some issues. We won't be able to fix this remotely so I would like to arrange for an engineer to come to take a look at this for you. 

I just need to confirm the address to ensure we are booking the visit on the correct account. I have sent you a direct message to allow us to do this with you in a private space. If you are using a PC/Laptop then you can just click on the little ✉ at the top right-hand side of the page to access your inbox. If you are on a mobile/tablet device then instead click on the little circle icon in the top right then select 'Messages'. 😊

Hi StealthDavid,

Thanks for coming back to via private message to confirm your information. 🤩

I have booked you in for the next available appointment. To view this please sign in to My Virgin Media here 👉 My VM. Once you log in scroll down to Orders & appointments then click on View your orders. Please note it can take up to 24 hours to show but you should also receive a text message with the details. You can also view this in the My VM app. If you have any issues with accessing your account or unable to see your visit, please do let us know and we’ll pop you a message to pass data protection and confirm the appointment details.

Just to confirm, 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 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.

We will continue to monitor your services and if we can see that the fault has cleared and the visit is no longer required we will cancel the appointment and let you know by text and email.

Let us know how the appointment goes. 😊

Take care.
