Can I suggest you create a post on the below virgin media forum.
http://community.virginmedia.com/t5/Up-to-50Mb-broadband/bd-p/50mb
The more people that complain the better as they will probably do something about it.
Please pass this around on any other forums you are members of!
I have also gone to watchdog regarding this poor service.

Right, because clearly absolutely everyone has the same fault as you and it can all be resolved with the flick of a switch.
Much as I sympathise with you not being able to leech the movies from Usenet as quickly as you'd like there are a number of different faults that affect all tiers of cable services and there is no magic bullet that will resolve all of them.
A flood of people posting there will simply guarantee that none of the individual issues will get addressed. VM are very aware of issues on the 50Mbit service they actually have quite strong network analysis tools.

Broadbandings, rather than getting on the defensive about it if they are aware of the fault why do I get stupid people repeating the same fault diagnoises, engineers doing the same things time and time again when one has already said theres a problem. Why dont they say there is a problem and hold their hands up rather than promising all the time its ok!
For instance downloading from i tunes which is 100% legal servicve albums are taking longer than they should to download etc.

Broadbandings, why are branding practically anyone complaining of poor performance on 50meg as pirates? Your attacking of 'leechers' is getting boring now, would you sooner have customers just doing mundane net activities sitting on the end of 50meg pipes?
So looking at the complaint, Giganews are guaranteeing that they can offer a download speed to match that of your ISP?
richardc1983
16-09-2009, 12:33
yes that is correct because that is what you are paying for.
I know other people on other ISP's on 50mb also people on 100mb that are getting full download speeds!
The thing is even if you lower your connection speed to say 20mb or 10mb on the 50mb service the speeds fluctuate even on that, so it is something related to the connection of 50mb .
When we were on the 20mb service full speeds constantly even at peak times.

Perhaps they need a private peering arrangement with VM.

Err the guy's main bone of contention centres around Usenet performance issues.
I merely pointed out that there are many factors that affect 50Mbit performance and a load of posts griping and complaining won't be constructive or conducive to issues being resolved.
I can only recommend you read my posting history and the conversations around this more closely given that I have 50Mbit stability issues whenever I do less 'mundance net activities' before coming to a general assumption about my points of view based on one post without context.
Do keep up, old bill. ;)

Some people on 50Mbit obviously are having issues, just as they are on all the other service tiers, but it's best not to get drawn into OP's attempt to start a 'crusade'.

My 20Mbit ran like hell sometimes at peak times while my 50Mbit when it's stable runs just fine. YMMV - Your Mileage May Vary.
And no Giganews don't guarantee speeds, that would be extremely stupid and impossible to back up in case of issues. Read their T+Cs, you are paying for access to their news cache carrying groups as advertised with retention and completion as advertised, they do not promise or advertise a download speed to you due to a variety of factors which can affect it over which they can have no control, same as your own ISP doesn't promise a speed even over their own network.
Thanks Broadbandings, I didn't think of checking a traceroute, doh!

i have noticed that my my 20mb ping rates have almost doubled reciently while a friend of mine who is on 50mb his connection is usually a rock solid 47-49mb
The thing is even if you lower your connection speed to say 20mb or 10mb on the 50mb service the speeds fluctuate even on that, so it is something related to the connection of 50mb .
I'm now on a 50Mb CMTS on the 20Mb tier on DOCSIS1.1 and I get 20Mb all the time now, with no exceptions, and my ping is always around the 15ms to London. When I was on an old DOCSIS1 CMTS I was getting terrible speeds and terrible pings however that was due to oversubscription.
So I guess, some of us 20Mb people on the new 50Mb infrastructure aren't experiencing these same problems.

Broadbandings how do you explain when you reduce the speed of the connection manually on the newsgroup client to say 10mb the speeds still fluctuate massively even though u are not not downloading at 50mb.
However if you was on 10mb from vm you would get a consisten speed the same as on 20mb!
Its deffo at VM end!
Its a cable connection they shud guarantee the speed! Otherwise why not offer a 100mb service and say its upto 100mb if its that easy to sell a product!

Read my post again, I never said that it wasn't at the VM side, just that there was no guarantee from the NNTP provider of performance.
You work in IT so I would hope I don't need to explain overbooking of bandwidth to you.

Broadbandings there is no need for arrogance it really doesnt become you.
I dont know what the problem is I just know its on VM side as they have already said they are doing testing of the newsgroups compared to the 20mb service.
Ignitionnet
16-09-2009, 21:01
It wasn't arrogance, you're the one who works in IT and thinks 28GBP/month buys you a guaranteed on-demand 50Mbps. A number of people here who work in and outside IT will tell you that's not going to happen.
Cable can guarantee a peak speed, you will be connected to the VM network at a rate-shaped 53Mbit or you will not be connected at all, but whether that 53Mbit is available is a very different story.

My brother works in IT also at network level and he also agrees that its not good enough.
A cable connection should be near spot on 50mb as they advertise it for small business as well and heavy users, this is how it was sold to me.
The speeds fluctuate you can get 10mb then 18mb, as I have said many times before.
20mb we got either 18mb or 20mb which didnt really affect the dl speed at all.
The 50mb is all over the place! This is the party your not listening to!!!!!!!!

Uhmm, you will find that 50Mb is not sold as a definitive speed, its sold as up to - VM have certain responsibilities to advertise it in that way. And not to put too fine a point on it, but that service tier is not sold to small businesses.

Again I never said that your performance was good enough I said that there was no guarantee of 50Mbit.
There is no 50Mbit cable service available for businesses of any size at this time, and services that are advertised for 'heavy' users doesn't mean they are any good just that you can cane the hell out of them without having the bandwidth police knock on your door.
I totally agree you've an issue, I totally agree it lies at or beyond your cable modem on VM's network, I just don't agree with your black and white view of things and think your 'crusade' will be counter-productive and your generalisations on the performance of the 50Mbit service as a whole unwarranted.
If anything your doing tihs will cloud your own issue as it'll be lost amongst a ton of non-issues. 50Mbit has a PEBKAC (Problem Exists Between Keyboard And Chair) rate even worse than the other services.
I also am not overly fond of people who whip out that they 'work in IT', as we both know there are several ways to work in IT and a lot of them give you absolutely no knowledge relevant to cable or ISP networks as a whole, even down to people who work in enterprise network environments.

I would doubt that seriously, no "other" ISP would seriously, with a copper backbone, be able to offer or get anywhere near those speeds. Seriously, it's probably a variety of issues, powerlevels, overloaded UBR, poor connection, etc etc, there could be a variety of issues.
Go to: 192.168.100.1 - in your browser and post the upstream and downstream power levels - It may have already been said, so if it has please ignore.
Flooding that thread, will not help. It will simply, slow things down.

That's actually just 1 disconnect you have there, the 'locked and synced' message doesn't appear to mean anything.
In any case all is well with me now.
Richard as i said NO! ISP on ANY! Network can guarentee u get top speeds 100% of the time.
its impossible to guarentee speeds 100% of the time on any network.

:LOL:
Whether there experts or not theres ways of communicating with people and wrong ways.
Then i suggest you look at your self. :rolleyes:

:LOL:
i have the right to report Virgin to the ISPA when they are not offering me ANY kind of service, when my service is non existant for a large portion of the day as it has been when i have reported it.
My problems have not only been down to poor speeds, but loss of service also.
Ok folks let's stick to the topic.

im on the new infrastructure on 20mb and reciently pings have almost doubled to websites.
Any chance of pings / traceroutes and stuff showing this?

The bits in red are probably causing the issue.

You can't really say that without knowing the up time of the modem. If it's been online for 2 weeks those numbers are fine. Apart from DS-3 the other two are uncorrectables from coming online and before getting FEC sync.
Leading on from that - Richard, when was the last time in your modem logs that you saw this message:
TLV-11 - unrecognized OID

Thanks - there is nothing in that lot to suggest issues. Each DHCP renew is 3.5 days apart so no major frequent errors. I get 10+ T3 timeouts a day.
I'm sticking with a firmware problem in the modem.
In other news those idle buggers at VM should really get a ToD server going serving Leeds.

Indeed, it would be interesting to know if they are increasing, and something else to keep an eye on. In my opinion, even low level RS errors can be a sign of an issue with DS signals.

That few over a week and a half or more (note the 3 DHCP renewals) shouldn't cause ongoing performance issues though, especially given that most are corrected so won't affect performance anyways.

VM have told me on the phone that the Noise Ratio levels are constantly up and down and think this may now be the problem?
Is that a reasonable assumption for them to make?

Technical support should have the tools to make that conclusion, it may be the cause of your problems. Whether that is down to the modem, or other interference on the line would have to be looked into.

Depends how up and down they are. That they are finally noticing it now is somewhat odd given the extremely comprehensive stats they should have, though I'm not sure how the stats are for the newer equipment.
If the cretins hadn't taken away the ability to self-monitor modems I could have shown you how to set up PRTG / MRTG to monitor some counters in the modem for signs of upstream disturbance :mad:
