Free "upgrade" 20mb to 60mb, wish I hadn't...

Ok, on Friday I changed from my trusty Ambit 256 modem (rock stable 20mb connection 24/7) to the Superhub, and so I could get my free upgrade to 60mb.

My connection has gone from brilliant (albeit 20mb) to terrible, unusable, unsteady, laggy, whatever else you want to call it. I call it completely unacceptable.

Here's my thinkbroadband graph from last thursday (Ambit modem):



And from Friday, before I upgraded to superhub:



And here's Friday after I upgraded to superhub:



Saturday:



And finally, today's:



As you can see, the switch to the superhub wrecked my connection. The internet is unusable, Youtube won't play without constant buffering, neither will iPlayer or anything else for that matter.

I'm using the Superhub in modem only mode, as is recommended. Here are my settings:

I'm about 20 feet from the street cabinet, if that means anything. I'm using a -15dB forward path attenuator.

Any ideas about what I can do to get them to sort it out?

Thanks,

Gareth

Re: Free "upgrade" 20mb to 60mb, wish I hadn't...

I don't know how to post up graphs like that, but in keeping with the title ..........."I wish I hadn't"....... I am in complete agreement?

We upgraded from our 10Mbs to the 60Mbs, and all is not well

The speed is not the problem, its this new "super-hub" the Router side of it is so poor, we cant even use the lap top or I-Pad in another room, for most of the time.

Its only after 22.00 that the signal is strong enough to use in another room

I think most people agree that the Superhub is left in modem only mode.

To have your IP address monitored, Google "thinkbroadband monitor".

I've posted the same over at the VM Help Community, here's the link: http://community.virginmedia.com/t5/...t/td-p/1193573

Thats not entirely the fault of the superhub. Wifi issues and constant rebooting yes.

But if you are going from 20meg to anything higher then you move from the old legacy network to the DOCSIS 3 network. So essentially they are moving you from a nice empty network to a highly congested one. Yay.

Sorry to hear your probs on 60mb.
Daughter had visit from virgin tech today, advised her to hold off going 20 to 60 as new ver of shub to be introduced to improve on original spec.
(No date given for new ver, most likely statement to be made soon)

Re: Free "upgrade" 20mb to 60mb, wish I hadn't...

I got moved from 50Mb to 100Mb just a few days ago, i then got an e-mail to say that i'd been upgraded, and in the e-mail there is a button to click to get the superhub, i'm defo not touching it till it works correctly, with my old set up i'm getting between 94Mb and 98Mb download speeds, that'll do for me, i'm not risking fitting a new superhub for it to bugger it all up!

Re: Free "upgrade" 20mb to 60mb, wish I hadn't...

Same has happenned to me. Although my wi-fi issues aren't as bad.

I had a 99% connectivity with 10MB. With 60MB It's around 40% to 70%.

That is with both wired and wireless! I assume it's due to over subscription.

Re: Free "upgrade" 20mb to 60mb, wish I hadn't...

This is disgusting. I've had my fare share of Pooperhubs and gone straight to the top as a result of there inferior design, performance and reliability. All of which spanned from there release to Christmas just gone. I'm shocked (although not that much) that VM note there hardware is at fault and suggest modem only mode? How about a product recall (which is long overdue) and address the root of the problem

I do feel for you and others who are not pre-warned about there poor performance. A quick call to the CEO's office is order I would say.

TiVo is moving from docsis3 to docsis 1 so hopefully that can sort issues like this out

Happened in my area last week, can't say if it's everywhere but makes sense to do that

Re: Free "upgrade" 20mb to 60mb, wish I hadn't...

the OP is hard proof that lower latency lower speed = more snappy responsive connection than high latency, congested high speed.

whilst the superhub adds jitter it doesnt add that amount, thats docsis3 congestion whilst the old docsis1 was clearly lower utilised.

I thought TV and BB were totally separate anyway. Are you saying that some of the TV stuff gets delivered over the same channels that get used for BB?
