Im trying to set up a home network with my broadband connection. Im really good with computers until it comes to networking. First i tried a router. THe internet on my copmputer works. the other it does not. It shows activity for that port. And the computer shows that its connected to the network. BUt i get a message from my broadband serivce saying that my account is active, but it doesnt recognize my ip number. Instructions state that I need to reset my cable modem. I tried that. Still nothing. I was told by a guy at work who knows a fair amount about networking to buy a hub. He says my problem with the router is that both computers were trying to use the same IP adrese. And that i would have to assign an IP number to the other comp. BUt if i get a hub. I wont have to. So i got a hub. And still same message when I go to the net. Any help would be greatly appreciated to aleviate this net headache.

These things are tricky to diagnose over the Internet - but I think it's likely that your problem has to do with MAC addresses.

Every cable modem I've toyed with has a tendency to get "attached" to the MAC address of the device it communicates with. Sounds like you've had it connected to your computer's Ethernet card (which has a MAC address of it's own). Now you're asking it to talk to the router, and you get nothing.

Some routers have a software utility that copies the computer's MAC address to a PROM in the router. If yours doesn't have such a utility, the fix may be to simply power down the cable modem for a while (not connected to the computer), then turn it back on and connect to the router.

Hopefully this helps:
