To initially setup the router, it's easiest if you configure it using wired connections, i.e. ethernet between the router and PC. Once you have the router config setup, especially the wireless info of encryption type, network name and stuff, then move over to wireless between the PC and router.

Normally the IP settings of your network are all auto established by your router. Thus when you click on network settings for your network connection, check properties for the card, and internet protocol (TCP/IP) properties make sure that is all set to do things automagically.
