The original post asked about a 2100, and the links refer to that model. In any case, you will not need any drivers for what you want to do. Drivers are only required for usb connections - ethernet connections use no drivers.

As I said above, you will need to buy a 4-port wireless router (linksys, dlink, etc.), as well as a wireless card for the laptop if it does not have wireless built-in. You would 1) connect the phone line to the westell modem; 2) connect the modem to the router via ethernet; 3) connect the desktop to the router via ethernet. The router configuration will allow you to enter the login information for verizon. The router would assign ip addresses to your computers automatically.
