if you have a Cable Provider and you have a Router and you would like to setup with your internet connection .
You can install the router the way every router should be installed without the CD . . .
Plug a cable from your computer to a LAN port of your router not the internet WAN..
Then look under your router for the IP information and type that in a browser (internet explorer firefox etc..)
Enter the default user name and password that might be written on the router also..
And from there you have to configure it yourself there might be some sort of setup wizard to help in there..
