View Full Version : What now?

I have the VIP package and apart from Broadband everything is ok.
Broadband is awful and the fastest download speed I have achieved is 5mb and the service dropped out more times than it was worth. I reported this and they identified a node(?) or something. This was repaired in jig time with the download speed never increasing but the dropping out stopping almost entirely.

I contacted VM and a very nice lady downgraded the service to 10mb and I saved a few baw bees.
Trouble is that the download speed is under 1mb and I have only had one drop out in 5 days.
I am using a router and am realistic about not achieving top speeds but where do I go now?

Cheers

Firstly can you post the usual power levels, SNR levels, frequency of the modem, also try bypassing the router (modem connected directly to the PC) and then do a few speed tests at different times of the day. This'll help the techies on the site point you at least in the right direction

Thanks for quick response:

Sorry to be such a PITA but I dont know what this means.

I have tried hooking directly to PC and speeds are still low but I know I wont get lightning speeds using a router. I can live with that because alternatives are few and far between.

when connected directly to the modem (might work through the router as well) type in http://192.168.100.1 and login using the details supplied (it tells you the default username/password) all the details asked for are within them pages. Please though do not post your mac address/serial number

You can do it whilst connected via a router.

Incorrect, the 10240000 and 512000 data rates are for 10Mb down and 500Kb up

A techie should be about soon to check your power/snr levels ;)

He is definitely on 10 Mbits/s, the problem is how to measure the speed, be specific with Mbits and MBytes, there is a big difference!

Yeah, that was my mistake, i read the Frequency by accident :p

I take it that this thread is now effectively closed.
Thanks for the replies guys!

I will now refer the matter back to Virgin in the hope of some sort of resolution.

Have you tried the virginmedia.support.broadband newsgroup? That will get you straight through to second-level techs without being fobbed off by the "someone will call you back" bs http://www.virginmedia.com/customers/newsgroups/

Possible oversubscription on UBR?

The uBR is like a local exchange, oversubscription means that the may be to many customers connected to that uBR causing congestion so it needs to be upgraded to alleviate this problem.

Makes sense now.

So its back to Virgin I suppose.

How would I let virgin know that slow speeds are down to my local UBR being over subscribed and that it's causing me problems when using the internet? Im struggling to browse on 2 to 3 computers at the same time even though I am on 10mb due to only getting around 2mb between 6-10.30.

Is there anything they can do to help the problem, like making my speed not go lower than a certain speed?

Sorry to jump on this thread but there is no point starting another on the same subject.

Not really you would need to call in to tell them you have an issue.

Below are a couple of links regards Traffic Management.

They almost certainly know already and they don't give a ****. Expect it to get worse if they roll out 50MB to your area.

They already know about the UBRs being over subscribed.

They could spend some of the money they get, but most of it goes to the bank that they owe money to and they paid mega bucks to them film stars to advertise for them.

Will get better actually, as 20Mbit users on being moved onto docsis3 frequences thus freeing up bandwith for the rest of the other tiers.

Course, this wont help much as VM will just see it as a way to push even more customers on!

Have you rang Tech Support to see what they have to say about your issue.

I have not yet called tech support but will tomorrow.
They have already found a problem (node?) and fixed it but all that really happened was that I had fewer drops out.

Please mind your langauge, even semi-hiding the swear word still impacts a lot of meaning that is unacceptable on this family forum.
As for 50Mb it'll be run on a seperate system that eventually 20Mb should move to so should have no negative impact on oversubscription and should hopefully relieve some of it.
