Upload Speed Issues

I have been getting poor upload speeds over the past week or so, though download speeds are as expected. This problem persists despite restarting the hub 3, having only one device connected directly via ethernet and over different devices.

I am starting to think its an issue in the area but nothing has flagged up on the service status page.

Re: Upload Speed Issues

Upstream channels are dropping qam and you are getting too many T3's. You need VM to look at the connection in more detail.. Either call it in and report it or wait for a VM person to get here in a day or so.

In the meantime can you set up a free and secure “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph” (as per instructions on the TB website) when it starts to develop.

Re: Upload Speed Issues

Thought as much, will wait for the guys on here to respond since my experience with the phone support has unfortunately been less than stellar previously.

I created a BQM previously, so here is the lvie graph:

Re: Upload Speed Issues

Hi Valdis

 

Thanks for posting and welcome to the community. My apologies for the broadband issues. 

 

I've ran a fault diagnostic and it's come up with the following; 

 

There is an SNR (signal to noise ratio) affecting your service. You might find that your Virgin Fibre, Virgin TV or TiVo® services are intermittent, with the picture freezing or disappearing now and then. We are sorry and our engineers are working hard to resolve this for you. Your fault reference is F009206106. 

 

The estimated fix date is the 12th August 2021 at 4pm. 

 

Kind regards,
