Are you using a wired Ethernet connection to the VM hub or a wireless connection? Wireless is easily disrupted by a number of external factors, so a wired test is the best way to get a true picture of what speed your line is able to achieve. It also helps to pinpoint if the issue is with the wireless or your line.
Are you seeing slow speeds all day or only at peak times (typically 4pm-11pm weekdays and weekends)? Some areas are suffering with over utilisation, which results in very slow speeds at peak times but full speed at off peak times.
If off peak wired tests are slow then some hub stats might help. Go to http://192.168.0.1/ (or http://192.168.100.1/ if you are in modem mode) to get the VM hub GUI. Don't login but instead click on Router Status which is either a button in the top right of the screen or a text link at the bottom of the screen depending on which hub you have. Click on the Downstream, Upstream and Network Log sections and copy & paste the figures from those screens and post them here, don't worry about the formatting or you can post screenshots if that is easier. Be careful to edit out or obscure any reference to your WAN IP in the log to protect your privacy.
The community can have a look for you and see if anything in the figures looks wrong and advise accordingly. Or you can wait for the VM staff to pick up this thread (can take over a week) and run checks on your line.

Sorry to hear you're having trouble with your connection.
I've run a diagnostic on your equipment and I can see an issue with your signal levels. I've sent you a private message (purple envelope at the top right of your screen) to arrange for a technician to take a look.

Well I thought this had been resolved.. after being promised that in May this year we would be receiving a "big" upgrade to the network in my area..
In the last two months it has got to the point most evenings from 18:00 onwards we have to use mobile phones for internet because the virgin media provides 200mb... doesn't even go past KB's... which is rather interesting for £50 pound a month...
What are we going to do virgin??
Last time a engineer came round and did a speed test on his iPhone at 13:00 in the afternoon came back at a good speed!! Well that's not really a surprise... there is no demand on the network.
I think it's getting to the point I'm going to need to cancel virgin internet if this cannot be resolved!
