As far as I'm aware Tiscali is not a cable internet provider, therefore you have a router which only supports the Virgin Media cable service. You need to get it replaced with a router that works with a normal line, this one is designed for cable lines. :)
Oh and by the way, Belkin's support line is no longer free, it's national rate. It'll tell you to ring another number if you ring the 0800 one.
