Please read post #2. No software or driver is required.... you access the router settings by using a web browser (eg: Internet Explorer, Firefox, Chrome, Netscape, Mozilla, etc.)
Most routers are accessed using address 191.168.1.1 (but yours could be different) and all require a username and password. Username = admin, password = password (default) but consult the router documentation to determine what the exact username and password is. If the password is different than what I posted, that means it's been changed from default and will require the user to reset the router using a hidden push button switch on the backside of the router. Then try using the default username of "admin" and password of "password".
