Hi,just my 2 cents here. I also have a cable modem hooked up via ethernet cable.I first tried to connect both using a hub.I couldn't get that to work.Members suggested I try a router,which probably would have worked but I ended up getting a second ethernet card,which I used to connect to the Empeg using a static address as suggested by others.Just make sure you use a crossover cable. The one I bought is label "crossover" right on it.
