A wireless router usually has provisions for wired ethernet connections as well, both Cat 5 and USB cables. Wireless is good for laptops, or you can get a wireless PCI card for a desktop computer. Cat 5 is the best way to go; it sounds like you are connected that way. USB connections are slower. Do you know if the ethernet card (or NIC) is working? Go to Start/Run and enter cmd & Enter. Type ipconfig /all to see the NIC address and any network connections. (to get out of this window, type exit & Enter). You could also go to the Device Manager on your PC and see if the network card shows up there and has a driver installed. The file you mentioned may be for that.
