I'm sure we will easily be able to determine your exact problem and provide you with an easy solution given all the great info you supplied us with. /sarcasm
You want people to help you, but you provide absolutley no details as to what the problem is, other than "my internet isn't working." What kind of internet connection do you have? Dial up? Broadband? We aren't mind readers, we need some details in order to diagnose your problem.
i know the solution...just plug that wire thingy in the internet thingy...remove that one red thing from the network thing and click on that one icon...then the only step left is to type that thing in under that program thingy and then ur set son..and ur big cousin will no longer have to look at ur ugly face.
