ThomRU,
Your device at the very least, should have come with a pamphlet and a CD pre packaged in the box by the manufacturer. As Health Edge stated, the device comes pre-secured by the manufacturer and there is a label right on it that displays the Network Name (SSID) and key or network password.

As for the Home Network Security Check application, it only works in compatibility mode. This is an issue that we are aware of. It seems that Microsoft left the compatibility feature out in IE 11. But I can tell you that the application will only verify if the network is secure, which it will be by default when using factory settings on your device. For reference, here's a link to your device's user manual: http://media.cox.com/support/print_media/internet/equipment/Netgear_CG3000D_User_Guide.pdf
**edit** Thank you Health Edge for your never ending fountain of knowledge 
Hi Colleen, the only thing in the box was a phamplet on how to hook it up. AND you talk to me like I should have known the silly network name and password was on the thing. Instructions would have been nice - or at least something telling me where to go online for the silly instructions. The girl at the solution store had told me their would be usage instructions on the inside on how to name the network and set a different password. I hooked it up and didn't even have a clue if anyone in the neighborhood could log on or what. There wasn't even anything telling me that the password was on the label on the side of the thing, and I couldn't even log on to it. I have been having horrible connection problems with Cox and after this fiasco wishing I would have taken my friends advice who left cox for the bad connections for something else.
Thanks to healthedge I knew what to do. I am certainly glad it was healthedge helping me and not you with your attitude. Cox needs to give their people some lessons on how to deal with customers better you came across rudely now that I am rereading that.
