My mum's modem has just stopped working. I stupidly said I would set her up wirelessly. But as she is with Virgin, I am having trouble. Firtly, I purchased a router from PC World. Do I also need a modem as well?? If so, what is the basic modem I can get? Am I right in thinking for BT / Sky broadband etc that you just need a wireless modem, but for Cable you need a modem and a router?? My Sky wireless was straight forward to set up, and I need some advise PLEASE!!!!
