Its a linksys 4 port wired router. I am splitting my connection with my roommates and they want to download stuff. I'll have a p2p program running, and then my roommate runs a different p2p program and everything lags terribly. Basically its just so me and my other two roommates can run whatever p2p they want and download what they want without lagging the entire network. the other two computers don't do any downloading.
