Roadrunner and Networking

I have Roadrunner (Time Warner) internet service using a cable modem. The cable modem is a Motorola SB-4100 which connects to the computer via a USB connection not a network card, although there is an ethernet plugin jack for an ethernet cable on the modem. Roadrunner assigns a single IP address, dynamically.
I just purchased from D-Link its DWL-920 package containing a DWL 1000 Access Point and two DWL 120 USB adapters. There are three manuals, 2 CDs and a quick start-up guide and, although a pretty experienced user, I find the instructions baffling.
I have two computers and simply want to network computer A (which Roadrunner connects to) to another computer (B) and be able to access the internet from both computers and share files. The DWL 120s and all drivers are installed and all devices seem to be working fine. When I run the AP software, and it searches for the access point, it freezes up. What am I doing wrong? Do I need a network card or routher and if so how do I configure all of this? I'm assuming a router would allow me to network for internet access but not file sharing.
Any suggestions or experiences?

I would not opt for wireless unless it was extremely difficult to run CAT 5 network cable (http://duxcw.com/digest/Howto/network/cable/cable1.htm ) or you need some workstation mobility. Your wireless kit should work, but you are going to have a much more expensive and complicated network and it is not going to be as fast. I would send the wireless kit back and purchase a router/switch combination such as the D-Link DI-704 or SMC Barricade (http://duxcw.com/digest/Reviews/Network/smc/smc7004br/smc7004br.htm). My experience with the DI-701 (http://duxcw.com/digest/Reviews/Network/dlink/di701/di701.htm) indicates that the Barricade may be a better choice. There are many router/switches from many manufacturers to choose from. Before proceeding I would suggest putting a network adapter in your computer and making sure that the cable MODEM will work with the Ethernet interface. I know of no router that has a USB WAN (Wide Area Network; e.g., the Internet) interface to connect to a cable MODEM. A router/switch will allow local file and printer sharing. Larry
