I think I'm having the same problem as someone else, almost. I have a Speedstream 5360 ADSL modem and I am trying to hook two computers up to it. I thought it wouldn't be that hard so I just went to Radio Shack and the guy told me to buy a "Ethernet 10 base-t splitter." Do I connected the "hub" side to the modem and the pc sides (obviously) to the pc's. Only neither of them work... shouldn't at least 1 of them work, is it possible I just bought a junky splitter or what??
