I need to connec this router to my computer but I do not have the software to do it. what should I do?

You don't need a software to connect a router to your computer. All you have to do is to plug the ethernet cable at the back of the router to the computer. If you need to access the internet connection through your router. Please note, if you have cable internet connection, you can copy/clone the MAC to your router. If you have DSL that requires user name and password, you can choose PPPoE, enter the user name and password and apply the changes.
