Only the one that that company uses.

you will need to install the usb drivers that accompanied this motorola modem

I have a similar problem. The common denominator seems to be the SB5101. I have a brand new Belkin Surf 300N, same issue. The modem will not give DHCP to the router. I can connect fine via ethernet to the modem directly.
This modem seems to be a dinosaur.

You need to input IP and DNS information in windows. I can only help you where to input but you need to contact your ISP for IP address.

you cant connect usb and ethernet on that modem at the same time you have to use a router

all you need to do is to connect the ethernet cable to the internet port on the back of the linksys router and then plug the routers power cord into the wall and you should be ready to go.

The easiest way to fix this problem is to not use the software CD that came with you WRT54G. If you type in the ip address of the router (usually for this model the default is 192.168.1.1) in the web browser, you should come to the firmware on the router. After that, log in to the router (usually the user name is admin and the password is either blank or admin). This will show you all of the configurations for the router. Make sure on the first page you have your router set up as DHCP. This will have the modem give your "router" an ip address from your cable company. From there you can set up you router your self.

You have to reset the modem from behind (little pin hole) with the modem and router not connected via ethernet, the let it restart and reset the router after both are reset connect the ethernet cable between them.

This web page has a wonderful graphic step by step to use port forward for your linksys router:
