Thanks for the reply. I made the request for a friend in a senior center who just obtained a "new" computer. She read the name on the side of a tiny USB device that she said was her wireless connection to the senior center's Wi-Fi. If, indeed, the number I listed is for a wired connection, I am looking for the wrong driver. But I'll follow through.
