Ok, i have two other roomates, and we just purchased AT&T @Home Cable internet service. Now the installation guy gave me a tiny usb plug that was connected to the cable that went in to the cable modem. That usb is currently in my computer. I just bought cat5 cables, a router, and ethernet cards. the cards are in the computers, and their drivers are installed. Now if someone could tell me exactly how to finish the job, so that all three computers can use the cable internet at the same time, i would greatly appreciate it. I am completely new at this networking stuff, so a very detailed explanation would help a lot. Oh yeah, and also i don't really know the lingo and how to change ips or anything. so if anyone can help me out of this frustration, it would really be prime. Thank you very much.
