See to step the WiFi on the router, input a Wireless SSID, i.e. name of something, give it a name, can be anything. Then you need to setup a security mode and password. The mode is how the broadcast is encrypted, i.e. WPA or WPA 2 is the best and most secure. Setting a password can be anything that you'll remember. This is the password that you'll use to enter in on the wireless PC to connect to the router.
Can use the install wizard CD or it's preferred to log into the routers web page at 192.168.0.1
