I'm a 20mb subscriber which is fine during the day time. I generally get 12-15mb out of it.

But the evenings are now down to <2mb (currently ~1200kb) and it's becoming a pain to use.

Is there any course of action I can try to get a better service ?

Do i just call customer service and complain ?

I wouldn't personally ring customer services first without letting tech support look at your connection. You're got to give VM a chance of checking their equipment on your connection before complaining. May be something silly, then again it may not.

Just out of interest what modem do you have?
If you post you're modem signal page here, someone will probably tell you if everything's OK with your modem (SNR, power levels, etc).

No as they would transfer you to Tech Support so we could check your connection, best just to call us o 151 option 3 from a Virgin landline or 0845 454 1111 option 3 from from any other phone and save waiting time.

You could also try this below as Noggo said.

---------------------------------------------------------------------------
Post what modem you have and your power levels from your config pages of your modem. The should be a sticker on the bottom saying what model.

Open a browser and in the address bar put or click the link > http://192.168.100.1/ the password and username are both root if required.

What I want you to post is the Downstream power levels including the SNR and the Upstream power levels for me thanks.

I'll raise it with faults then. Only reason I wasn't sure about that is that fine during day time. (currently 10mbit). So seems to just be local congestion. For the record I tried a download from blueyonder server and got about 35kb download which is pretty poor.

Modem is the "NTL 250" type

I didn't what to be the first to mention UBR capacity but as you did. Yes it does look a lot like it :(. I wouldn't class 10Mb during the daytime fine as well, you should be getting close to 19.5Mb when everything’s running OK.

From past experience I would personally go through virgins newsgroup group support in the evening when the problem is at its worst. They will check the state of your connection / UBR. You should get a better response back (fingers crossed and all that). If you do get what you need to here (over subscribed, capacity issues on the UBR) get a date (which will be 'subject to change') from them when the work is going to take place to resolve the issues. Once you're got the date, that's the time to speak to customer services about some reduced monthly subs, from when you first reported the problem to the estimated fix date.

Hope the above helps you out.

Laters,

oops almost forgot, I don't know much about the NTL modems (don't know much about ex-Telewest either, but more than ex-NTL), so if someone could shed some light on the NTL 250's compatibility with 20Mb service and state of affairs regarding the power levels, SNR etc.

Also have a look here: http://www.cableforum.co.uk/board/34527446-post6.html to help you with what info newsgroup support may ask you for.

Re:
Start 2 simultaneous downloads from the VM demo games server plus 2 simultaneous downloads of Zen test files. That's four file downloads happening at once! Now add up each of the four download speeds to get your accurate download rate.

They only ask for two simultaneous downloads now from VM demo server.

Do what I did? Downgrade to the 2 meg service and save £19/month :D

Noggo
05-11-2008, 18:19
Yep downgrading is an option. Normally and if you have a valid reason for it, VM will give you a faulty over subscribed 20 Meg connection for the price around 2 Meg untill the problem is resolved (half price). Then at least during the day you get 10 or so Meg and hit or miss in the evening / weekend.

Yep I get exactly the same thing..
Desktop or laptop direct wired or via the router. Nearly full 20mbit during the earlier part of the day, drops off from around 5pm until 12am then it's back up to decent speeds. It was fine on 10mbit but started being very intermittent when I upgraded a week or so ago.

This isn't much use to me as I'm at work during the day and only use my home internet in the evenings.
I've been off sick today and have been able to monitor the speed all day. It's definitely a lot slower in the evenings. Spoken with 'technical support' twice and they say nothing's wrong.. as an IT professional I find it very painful to speak with the indian call centre and can't bring myself to call them again ;)

Currently around 7mbit.
Where do you guys do that test posted above?

If you are a Virgin Media customer then the best speedtest is from the link below.

Have you tried going to this link to check your speeds http://gamefiles.virginmedia.com/

click on blueyondergames>demos>then click on at least 2 large files around 400/500 mb and save them to your desktop, and then wait a couple of minutes then write down the transfer rates on the files that are running > times them by 8 and you will get a truer download speed.

Remember to stop and delete the files.



i.e : 250kBps X 8 = 2MB, 500kBps X 8 = 4MB, 1250kBps X 8 = 10MB, 2500kBps X 8 = 20MB

So if I call customer services will they give me a credit until decent service is restored ?

Yes it is out of spec, 16QAM requires 55dBmV transmit power or lower to ensure proper operation.

DOCSIS specifies that cable modems must support an upstream transmit level range of +8 dBmV to +58 dBmV for QPSK, and +8 dBmV to +55 dBmV for 16-QAM

Overdriving the transmitter causes distortion, distortion causes upstream SNR problems, upstream SNR problems cause slow speeds.

From the customer's modem, DPC2100, datasheet, http://www.arenaservicesinc.com/manuals/Cable_Modems/SA/DPC2100datasheet.pdf

Operating Level Range
+8dBmV to +58dBmV
+8dBmV to +55dBmV ( 8QAM, 16QAM )

I didn't mention that if it's transmitting that high it's also in itself indicative of a fault, either noise that the modem is trying to overcome to be heard or a bad upstream path that's overattenuated.

Either way 56dBmV on 16QAM is not at all good and is the equivalent of about 59-60dBmV on QPSK, a 16QAM signal having (ish) 2 times the peak symbol power of QPSK, which is likewise not good (16QAM symbol power = (2.5 x QPSK squared) / 2.

That's not the 'truth' there is no 'reduced service' apart from the 5Mbit that the 20Mbit goes down to when STM'd. There are no refunds for that though. That's probably what they were referring to. 1 to 3Mbit at peak times sucks and is certainly worth the refund mind.

yes stm,d was mentioned,what is the purpose for stm ? does it normally go on for long and should i be paying for 20mb and only getting 5mb,as a customer im not happy with this if thats the case:mad:

Are you on a router if so try a direct connection if possible.

Of course! Routers introduce 300,000 ms of latency don't they? and the firmware is set to only do this after 5pm as well :dunce:

I wish people would stop blaming a poor network on anything but. If it was his router then it would be poor all the time, geez....

Please try to be more respectful to the other members of CF..Many of the VM CS and VM techs do give their time freely on Cable Forum to help people resolve any issues they may have.

Indeed any helpful info you can provide will be very much appreciated and is much more likely to be respected IF you are as respectful of others.Rubbishing the help given in honesty is not helpful if accompanied by phrases such as 'inane drivel'.

I know it doesn't help much with the above but I'm on a Bromley UBR too :(

I'm glad I am not alone.

I'm on VIP package so not sure if I can downgrade to 10 Mb.

With your 10 Mb is that working at a constant decent speed all the time?

My 10mbit connection was absolutely fine before I upgraded to 20mbit. I tried it for a couple of weeks but was never happy.
The downgrade came through Sunday morning. I tried it at various times during the day and evening and it was a consistent 10mbit connection. I'll have another play around when I get home from work this evening as that's the time it usually misbehaved on the 20mbit connection and let you know how it goes.

Thank you.

I am almost at the point of considering dumping Virgin Broadband and going to someone like BE but that means also dumping the Virgin phone too and having to move back to BT.

Sounds like overkill I know but I do have another issue too and that is the slow upload speed available from Virgin.

Tested last night. I was using the connection pretty much from 7pm to 12am with a break at around 8:30 - 9:00pm to avoid getting STM'd..

Consistent 10mbit all evening.

Thanks - interesting!!!

Makes me think I should be downgrading to 10 Mb as well.

Just a little point on this one, like i have already pointed out and not saying this is going to be everyones problem BUT, if you have problems at 20Mb then downgrade to 10Mb and get consitent speeds at 10Mb, could there possibly be an issue with your setup?

From my point of view and obviously I am still on 20 Mb; it runs fine most of the day until we get to the late afternoon when I have had it go down to 256k. This doesn't happen every day but has happened several times.

I can't see how it could be anything wrong with my setup otherwise I would have thought I would have had problems all the time.

OK, just a thought. But to drop that much?

Not really as...
a) It would give me a 20mb connection out of peak hours then drop during peak hours then go back up around 12am. No changes to setup, no rebooting taking place.
b) I used to work for Telewest before VM took over as a 2nd line BB technician - so I know exactly the things to look for on a PC or home network that cause problems with cable BB connections.
c) I'm a Microsoft certified engineer with a 'proper' job in IT now (as opposed to working for TW!) and have a quite high understanding of PCs and networks ;)

Yes even the best of us miss things, as i sometimes do.

And also not everyone has certificates, high understanding, or a job in IT as you would know working as 2nd line support for BB. Even the most simple things can be missed because we are looking to in depth or think we know it all,(not saying that part is you).
