Are you connected to the wireless router with an ethernet cable? Generally, you want to hook it up this way first so you can configure it. If you are hooked up with a cable open your web browser and type in the following address: 192.168.1.1 this should get you to the router's web page. The default login for linksys is username: blank, password: admin

See if you can connect to the router in this way. If you can then we can go through the next steps or you can try using the above link.

Good luck.
