It's been awful for me, but there's so many factors since I'm networked with 3 other computers. But I just checked there's no downloading etc, I ran Adaware/Spybot on all PCs. Is there anything else I can do? Or is it VM's problem? Would be interesting to see some similar screenshots of other Virgin Media users.

It's not god-awful but it still affects me a lot on Counter Strike, the loss/spikey latency makes the recoil so random.
 
You could possibly try plugging your computer straight into the modem see if it gets any better.

if not could be noise in the line or something :(

Was talking to a friend and I'm getting closer to figuring out the problem.

Right now the setup is Cable Modem (Motorolla SB5100) -> PC (Acting as a router) -> Hub -> Other computers, and the cable modem is connected to the PC via a 1.0 USB port, which I've found out is limited to 5mb. ( http://www.virginmedia.com/help/ethernet/index.php )

He said I should buy a real router and it will fix all the problems. So the question is, which one do I buy that will be good and compatible?
 
lol you think thats bad, check mine out :) This is exactly the same through 2 routers as it is directly connecting to the modem

Code:
Ping statistics for 195.8.66.1:
    Packets: Sent = 50, Received = 46, Lost = 4 (8% loss),
Approximate round trip times in milli-seconds:
    Minimum = 29ms, Maximum = 76ms, Average = 42ms

Love 20mb!
 
Copy and Pasted wrong thing in first time around? i smell ninja edit.. :p

I'd get the line investigate for noise if your getting packet like that on all your connections bud

Fear my 20mb cable connection :p
 
lol yeah ninja edit there :p shhhhh

Well the loss doesnt always happen and everytime I phone up they say theres nothing wrong blah blah.

The conclusion, after wasting 5-10quid is that I have spyware on my macbook and erm thats it.

Code:
Ping statistics for 82.133.85.65:
    Packets: Sent = 50, Received = 43, Lost = 7 (14% loss),
Approximate round trip times in milli-seconds:
    Minimum = 25ms, Maximum = 89ms, Average = 46ms

Wooo ! :p

edit:

How would I get them to check the line? Everytime I ask if the UBR is having problems etc they say no, even though during peak times it seems to get overloaded but even now its struggling along!
 
In terms of finding out if their getting bogged down at their end then theres nothing you can do but ask.

In terms of testing the line for Noise then once again they are the only people with the equipment to do it. Just ring them up and say your getting "major packet loss" they'll send out an engineer and he'll look into it. ignore any stupid lecture they give you about white noise that could be caused by anything like a microwave. they'll say that to cover their bums but chances are within a week it'll be fixed :)
 
Thanks, will phone up next week.

But I can bet anything that when I try next week during the day it will be perfect as people are at work etc and when the kids go back to school the connection is fine, this is my arguement everytime with them but they never say yes we have a problem :/

Yep, this is one reason why I left NTL (VM) a few months back. I was sick and tired of incredibly unstable latency/packetloss in the evenings, I had an engineer round once but of course during the day it wasn't so bad and he reckoned some 'fixes' in the local area that day had sorted it.

So a couple of months later when things were getting so bad I couldn't browse (60% packet loss, latency anywhere from 7-700ms) they arranged to send out another engineer, but he never showed up and they claimed there was no record of it being booked in :rolleyes: That was the final straw so I used their price increase on the 10meg service (£35->£37) as a way of getting out of my 12 month contract.

What annoys me the most about mass-market ISPs like NTL/Sky is that their technical 'support' line staff all cater to the lowest denominator. I'm sure they are very good at telling people how to setup their email, what socket to plug an ethernet cable into etc but if you have a genuine problem then it is so frustrating to have to jump through all the hoops (plugging directly into modem, rebooting modem, rebooting pc, checking local cabling bla bla) that I've already done before calling them. If you have any kind of query that deviates from their script then they start trying to pigeon hole it into one of their boxes. If the person on the other end of the phone doesn't even know what 'packet loss' means in relation to an internet connection then it really doesn't fill me with any confidence that they can understand or fix my problem. They keep banging on about "is your speed slow for downloading?" etc.

Don't get me wrong, I'm a realist. I know that they need a lot of staff to cope with all the everyday queries they must get from novice internet users and hence they are trained to deal with that. But as someone who works in IT, and has been using the internet since the 90s I just wish I could get through quickly to someone with a modicum of experience and knowledge. At the end of the day, in all those years of using the internet, I have NEVER had to call a technical support line to subsequently find that the problem was something I could have resolved myself. The fact I'm calling a support line means that there is definitely a problem with my line or ISP somewhere or other.

I'm convinced that NTL have, in some regions, congestion somewhere on their network. The problem is that as long as browsing is fine, your line stats look good to the engineer, and speeds (not latency) are mostly OK, then they aren't going to do anything about it.
 
Update:

Bought a Linksys WRT54GS router. Just set it up. And the latency seems to just be as bad, pic:

Don't know what else to do but phone them up and complain about noise on the line or something, what are my other options to try and resolve this?

Perhaps theres a few settings in the router that I need to configure?
