Get your default gateway address say it comes up as 192.168.0.1 for example

Then you would open up internet explorer and type in 192.168.0.1 and it will prompt you for your router's username and password.

Please see your routers manual for the appropriate user name and pass code.
 
You can look at this: http://www.tomshardware.com/forum/38111-43-find-change-wireless-security .

Your question has almost no information, so the assumption that it is a password question is reasonable. Do you have Internet service at all? Can you get to the Internet if you connect to the router by wire? Is this the first time that you have set up a wireless connection to that router, or do you have other wireless devices in your house?

If the router is from your internet service provider, they will probably provide support. Until you provide more detail, we have to assume that your question is about passwords and is against forum rules.
