There isn't too much to configure in the router itself. Initially, enter an SSID (network name) to replace the default name and make sure that its wireless capabilty is switched on. Later you can set up encryption to "secure" the network so that others cannot connect to it.
In the laptop, you need to "Connect" to the wireless network by running the wireless adapter's software, scanning for "Available Wireless Networks", finding and highlighting the one that matches your router's SSID (network name) and selecting the option to "Connect" to it? Once "connected", the little icon will get its "halo" to indicate it is connected to that network and it should then get its IP address by DHCP from the router and you should have internet access.
