Make sure network name is the same on the laptop as on the router. IP should be auto on laptop.
Use Wpa2 security and make sure the key on both are the same.
Set it up for home, private use on the laptop.
One not so obvious... Is the router 802.11G wireless or 802.11N wireless. It's usually G.
Thats all I can help with at the mo.

Just thought....set up the router using wired cable and make notes on all wireless setting, so that you can copy what you need for the laptop.
