Hub 3 partial service (DS only))

Hi, three days ago my Virgin Broadband started dropping connection intermittently needing a restart of the hub each time. Since then it has got progressively worse and now drops out around every 15 minutes. 

I was running the hub in modem mode to an ASUS router so I reset the the hub to its original setting to see if that worked but still the same.

Most of the time I can’t get the Virgin Media app to connect to the hub and then when it does it says it’s fine.

When I run the network diagnostic on the PC it gives the error - Hub 3 partial service (DS only)).

Even when it does connect I’m only getting a speed of around 36megs when I’m on the 200meg plan.

Can someone please advise?

Thanks

Tony

Re: Hub 3 partial service (DS only))

Connect to the hub by clicking on this link http://192.168.0.1/  That should pull up the log in page for the hub.  But don't log in, just click on the link "Check router status"  That'll bring up a window with five tabs.  Open the Downstream tab.  Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here.  Post that, do the same for the Upstream and Network log.  You'll get an error message when you post the Network log, just click on "post" a second time.

Then we can check for any obvious problems with power, noise or error counts.

Of course if your Hub is back in modern mode that link won't work, but you'll know how to reach the log in page.

Re: Hub 3 partial service (DS only))

It's failed to provision the service properly, you are missing some of the DS channels entirely (hence the Partial Service messages) and because it's not too sure what it should be doing, it hasn't bonded the four US channels at all. The channels you do have seem quite 'noisy' and so there are excessive errors on them. The only thing you can reasonably do is to check all the cable connections are sound and no obvious damage anywhere, failing that it'll be an engineer visit.

Re: Hub 3 partial service (DS only))

In the network log there are numbers which aren't appearing in the message that I sent to you and are being replaced with asterisks in the email - I don't know if that has any bearing on your reply - just out of curiosity too, what are you looking out for to tell the channels are "noisy".

 

Thanks again
