Is there any difference if you disconnect the router and connect the main computer to the cable broadband on its own ?
I have two computers on a home network. They both are connected to a Linksys 4 port router. The main computer connects at a very slow speed. the second 900 MHz connects like a bullet. I have broadband cable hookup. It has a windows xp operating system, 1.2 MHz Intel processor, 256k memory. The computer works like its on dial-up speed.
