Netgear N600 Installation HELP!?!?

Ok I'm good with computers but not so much routers and modems and gateways and such.....I followed the cd instructions perfectly they even show you what to do that part is fool proof. The router cd than says we determined you use a static ip please type in your Default Gateway, DNS Servers, IP Adress and Subnet....I went into cmd prmpt did ipconfig /all wrote them all down jotted them in there and it constantly says internet connection failed after about two mintues of tryen to connect....Any other suggestions on what i should do or any other ways to find my information maybe i have the wrong ones..?
