We are running four pcs on a home network. The main pc is XP, the other three W2KPro. Set up is cable bb, four port hub, and is wired. Two of the W2K pcs are experiencing slow downs, and freezing, very reminiscent of the old days of MSN, when you would type, and nothing would appear for several minutes. Anyone have any suggestions as to how to remedy this, and would a router improve the whole set up? Cheers!
