Because either the "eclipse" device was a router, or the broadband service that was in use there provided multiple public IP's.

So... am i right with this... VM provides 1 IP address that both our PCs cant share at the same time. Why cant we both use it?.... but buying the mentioned wireless router (or any router?) or the VM wireless one will allow us to do this.
Every device on a network(the internet is just a very big network) must have it's own unique IP address, this is how data knows not only where it's going, but how to get there. Having two devices with the same IP would be like having you and your next door neighbour having the same house number. Yes buying a router(or getting the VM supplied one) will solve this.

Another point to make is that the internet seems very on/off at time. sometimes just wont connect to the PC for hours. i think it maybe to do with me trying the 2nd pc all the time but not too sure.
May be, may be not, you may just be in an over-subscribed area. Does the internet seem to go off at regular times of the day? You may have a problem with the signal level to your modem, or you may have another problem that only Virgin can (try) and diagnose. Best way to make sure it's not your equpment is to take the hub out completely and connect one pc straight to the CM.

so basically, my hub is never going to work - and this isnt anything strange.... i need to but a new router.?
Yes, using the house number analogy, imagine if your house was divided into flats, but the flats all shared the same house number. But you had a record of which flat requested every piece of mail that comes through the door. Well that's what a router does, allows multiple access through a single public IP, and records every request sent out, so that it know where to send ant replies it gets.

All a hub does is mirrors everything it sees on one port to every other port on it.

Hope this helps
