internet connection problems

I have two computers running Windows 2000. I also have a cable modem. I used to be able to unplug the cat5 cable running from the cable modem into my router and plug it directly into my computer (to obtain a semi-permanent IP address), and I still can do that on one of the two computers. The other computer loses its connectivity when I plug into it directly, but regains it when I reconnect to the router. As far as I can tell, the relevant settings are identical between the two computers, and I'm using the exact same cat5 cable.

Does anyone have any ideas as to what could be causing this and/or suggestions on how to correct it?

Hi Marilyn,
how many computers (MAC addresses) does your provider allow? I'm allowed 4, but because these MAC addresses get entered into some cache or table on the provider side, I cannot disconnect one computer and add another once I have exceeded a running total of 4 MAC Addresses.
What I mean is: suppose I had at some time connected different computers/filewalls/active-hubs A, B, C, D not necessarily at the same time. (I was playing with different configurations first two or three computers, then a fourth connection sharing box, then a active hub, then a filewall.)
Then I had filled up this cache thing. If I then tried to connect a new computer E (even if it was the only one connected) the connection was refused.
There is no timeout where a MAC address is deleted from the cache if it has not been seen for a while.
The provider has to reinitialize on his side to clear this cache and that can take a week of waiting.
