It is a virgin media modem that the daughter plugs her radio link into. Can you get some kind of splitter like they use in student flats?
Excuse me for being thick, but can I get one router/splitter that the PC plugs into and the wireless thingi plugs into that makes them totally separate from each other so they can be used at the same time via the Virgin modem?
Actually it's the same modem as mine and I've just looked and it's only got one lead out. Only one socket.
