Serious ping problems - erratic

I've been having erratic issues with ping for a few weeks now. Thought it might be a recurrence of an earlier issue with my coax cable, but no longer sure this is the case. Router stats:

I've posted most of this on previous pages, but will do so again. Ping is terrible this evening - and I note my upstream speed is down from its usual level in speedtest. Implies there's an upstream congestion issue?

There's nothing wrong with your connection data. You have the common problem of sharing your local network with too many users that Virginmedia have signed up to use it. 

You can complain of course, but...

Hi @Rogueywon thanks for getting back to us.

Sorry to hear of your ping issues and for any inconvenience this may be causing your household. I would like to have a look on your behalf. I am going to send you a private message. Please look out for the purple envelope in the top right of your screen.

Regards

Lee_R

After a week of being pretty much fine (other than the national outages on Tuesday, of course), the ping's gone to hell again this evening.

Hey Rogueywon, thanks for keeping the thread updated with this.

I am sorry to read the connection issue has re-occurred, I can see you've previously spoken to our forum team privately a couple of times and we've offered support with this.

Could you please confirm if this was a fix by tech visit we did last time and has your hub been replaced recently?

Upon our latest checks there are no known issues in your area network to explain this issue at this time.

Please, can you confirm whether you have any 3rd party equipment currently in use and if you have access to broadband and Wi Fi currently?

Let us know where you are with this and we're here to assist.

Your shared BQM is still showing over utilisation in peak hours, as pointed out by @jpeg1   last week.  The time scale for fixing such issues can be quite long.

But @Adri_G is following this, so hopefully they will be able to get something done to resolve it.
