Also, from looking it appears to just be a small USB stick modem, correct? If so, you can plug the Router into a open Ethernet port on your Computer (one end of cord into PC other into "Internet" port on router). Simply "Set up a small office or home network" and say "This computer connects directly to the internet". It should lead you through the steps and it should route internet access through the router and around the house.
If need be you change change some settings in the router page <192.168.1.1> and enable Wireless security, and change the channel of it for more range.
