What sort of security are you using on your router?
Some types, such as WPA are not supported.
The easiest solution if you are using WPA encryption would be to switch to another security mode, such as WEP.
Find your IP address. Easily done by googling Find ip address. go http://(PUT IP ADDRESS HERE) on Web browser.
