We've got a virgin media modem, and it seems to only allow one computer to connect at a time.
I've got some LAN Homeplug (lan over power line) devices.
Have got the virgin media modem plugged directly into a homeplug device, then the other computers connect with their own homeplug devices.
This only connects one computer to the internet, the others get a blank default gateway.
I'm wondering if I need a router?
Have looked at some comments from people who talk about getting a cable router (as against ADSL)
Any advice appreciated.
