I am also with Virgin and have a desktop and laptop.
I do not like bellkin. I have used a Linksys WRT 54G for three years. The deskptop and router are in the loft. The desktop connects to the router by ethernet cable - my choice, I could connect wirelessly with an adapter.
My laptop is wifi enabled as most laptops under 2 years old are. It connects wirelessly all over the house, in the summer house at the bottom of the garden and from my next door neighbour's house.
When you buy your router follow the instructions exactly. If you connect the laptop by ethernet during the setup it will find the connection once you disconnect the cable.
