As you all know, I've had a router sitting around my house for months.

Haven't used it yet.

Today, I decided to try setting it up. Well, I got the router plugged in right, and all the right lights were blinking - power, cable, one computer connection - but on the modem, I could just get power and cable. No connection. And so, I couldn't rout anything.

So, I unplugged it and came back online to ask the all important questions: What Is Wrong and How Do I Fix It?

My first guess is the router and cable modem fighting over IP addresses, and the router winning. Check the router manual/configuration to fix that.

That's extremly likely, espicaly if you've got a match brand pair. i assume they have web interfaces to reprogram them, if they have the same number, then bingo, youve got your problem. mine both have an internal ip by defult of 192.168.0.1 I changed my router's configuration to 192.168.1.1 and the setup works just fine.

If you haven't worked out the problem by this time, you could probably get more diagnostic output from the router's web interface. (I'm presuming it has one, but they almost always do.) There should be a way of scanning logs, or at least the output from the last connect attempt, and that may give you more information as to what the failure actually is.

For instance, it might be that your cable modem place is actually looking for the MAC address of your computer's ethernet card. If that's the problem, your router probably has an option to grab that information from your computer and pretend that it is its own; that might be a useful thing to enable.
