I'm assuming you're trying to do this wirelessly? The SSID is what your wireless router calls itself. You can find what this is by clicking on the wifi icon near the clock on your computer and seeing which one you're connected to. I can't give exact instructions, because you didn't say what operating system you're on; but just click on the wifi and it'll tell you in one of the options. ===================================================== Please rate me if you found this helpful, thanks.
