Do you get a connection? On the top bar of your desktop (after login) should be 
a symbol which looks like a bar graph, indicating the network is connected. If 
you hover the mouse over it you will get information.

If you have two little fireballs chasing each other in circles, it means the 
wireless can't connect to the router. And if you have a console with an "X" at 
the base, it means the connect was tried and failed.

What to do: if you have the bar graph your issue is with routing, you do have a 
connection. See other posts here which have thoughts on that.

If you have no bar graph, but the console and X, clicking on the icon will give 
you some status. It may give you a list of available access points, in which 
case look for yours and click it on the menu. With luck you will connect and can 
come back to ask about making that automatic. Note that you may need to provide 
a password if you have your access point set up right. Security is another 
issue, but default passwords (or none) are dangerous.

Hopefully that gets you going, or to more info you can report.
