I found something on the main computer and it's a 4-port powerline ethernet bridge (not sure its wot we're looking for).

The main computer is owned by the rest of the computer and they have got a less idea than i do so they'd be no help.

I just went onto the main computer and it's limewire says you're not fully connected to the network but its pretty good. It has been on for ages now and has taken tones of time to get to that point. I havnt tried any other p2p (p2p is like file sharing isnt it).
