Okay, right now I have cable internet and a 2 computer home network to share files, but mainly to share internet. I have the standard setup with two network cards in my main comp, one goes to the cable modem, the other goes to the hub. Then other computer has one network card that goes to the hub. Now I'm headed off to university, and I don't want to have to swap out a network card to my other computer and move the cable modem over and stuff (would create problems). I was told I could simply plug my cable modem into my hub, and then plug both computers into it, and do it that way? Then my computer could come and go freely, and wouldn't affect the other computers' connection? If I did this, I would be leaving the settings the same in my internet connection settings for my main computer (ie. exactly what my ISP says to do?) and chaning my other computer's settings to match (instead of the local network settings such as 192.168.0.2 IP and stuff). I tried that, and my main computer wouldn't connect to the net. Do I have to do something to get it to "see" the modem? Or should it just think a modem is directly connected to it? Now a few other things: - I do get two IPs from my ISP, and I've only been using the one up until now, so that's not a problem. - My hub has little lights that light up when something is connected (like when my other computer is off, the light is off because there is no connection, but when something makes a connection, the light goes on). The light does not go on when I plug the modem directly into the hub. I know the port works because I tested it, so it's not that. I'm thinking it might be just because the modem isn't a computer, and only a computer will make the light go on? I hope I explained that clearly enough. Thanks for any help you can offer.  Forgot one thing. I say "hub instead of router" in the thread title because ever other guide seems to say a router is needed for this job. I'm just hoping a hub will work too (although I know it won't give me the same speed).
