Are you running Windows XP or Vista on your computer? before you can download the drivers for this wireless USB network adapter you must first check if the hardware is being detected by your computer hence its useless to download the drivers. Normally if you connect the USB adapter on the back of your tower(I believe there are several USB ports on the back), a pop up windows on the system tray will inform you that it detected a new hardware(Found New Hardware) then the Found New Hardware Wizard will ask you if you want to install the device automatically or you will specify the location of the drivers, now if you don;t see this screen check your device manager if you will see anything that say's other device with a yellow exclamation or question mark(UBS device or Network controllers) right click and choose update driver and specify the location where you save the drivers, here's a link where you can download it; http://web.belkin.com/support/download/downloaddetails.asp?lang=1&download=1379
