I can't install a Linksys USB Network Adapter with a Rogers@home cable modem. Computer detect usb adapter but can't install driver from disk, keep saying unable to find drivers. I download the 75 KB zip file from Linksys and extract it to a disk. It has three files usb100tx.inf, usb100tx.sys and usb100tx.cat Am I missing any files? The Adapter is Model USB100TX.
