I have hooked 3 computes together using a router provided by Verizon. The router is rated 10/100mbps. Everything works but slave machines are slow when they have to talk to the box tagged as the server. The machines have enough horsepower but the link is slow. I thought of buying a dedicated mini hub, 8 ports, and trying that but unless you get into one of the gigabyte things, it seems they have the same transfer speed as the existing modem, 10/100.
Thus, in my mind I would gain nothing. Any advice would be greatly appreciated.
