cannot get dhcp address from cable modem, using mandrake 9.0


ok, i just got 2.2mbs charter pipeline internet, and installed it on the uplink port on my hub, which also has two computers on it. The one computer I am on now is a win2000 system, and it picked up an address from the cable modem first try.
I have a 3c905c-tx nic card installed on my linux box, and it has the 3c95x module for it, and it will work fine with a static ip address (i can access my 2000 computer when i have it hear). When i set it to dhcp it will go down and stay there. i have tried using dhcpcd, dhcpxd, and dhcp-client to get the ip address from the modem, all but dhcpcd show nothing. dhcpcd will eventually end up saying:

NO DHCPOFFERS recieved
No working leases in persistent database - sleeping.

when i use the drakconnect wizard and tell it to use a cable connection i'm able to set the dhcp client to one of the above three (this is under expert mode--->configure internet access).

I have tried almost every possible different way to connect with the few dhcp clients i have, and I know that my cable modem can dish out up to 16 addresses, so there is obviously something i haven't done yet. I have used linux for a while, but I am not near intermediate, if anyone can help please post one for me....thanks!!!

ok, a friend made me realize that my isp server might just be assigning me one ip address, and he was correct. I unhooked my 2000 computer and unplugged my cable modem so it lose its ip tables, and then hooked only my linux box up to it, and it picked up an ip address just fine. I'll set my linux box up to a dhcp server so i can both of them on the net. maybe me fixing my problem myself and putting it here will help someone else, but if not oh well, thanks anyway!

This is true. I work for an ISP and that is all you get. (a single IP address) Setting up Linux as a dhcp server will work.
OR
To add more computers on the cable modem, just attach it to a switch and then your computers to the switch. Assign static private IP address to your computers.
OR
If you have a router you can have it give out IPs via dhcp.
