As snoopz mentioned, you can not change the modem they gave you.
It is only if you use an ADSL connection that you can use your own modem combined router.
With VirginMedia, keep the modem that they gave you.
Then choose a Wireless cable router. Many people here reccomend the Linksys models.
eg. here:

You then plug the modem into the router through ethernet cable and connect to the router from each of your PC's via wireless.
The first time you connect a PC you will need to do it through ethernet to set it all up, but once that is done, you can use your machines wirelessly.
