Page 1 of How exactly do I set up WPA encryption on a new laptop ?

As in the heading. I`m familiar with setting up the wireless router, but I`m really getting bogged down trying to set up the laptop with WPA encryption. Despite using wizards etc and using the same key, I can`t get a connection to the router or beyond to the internet. An absolute idiots guide would be most welcome. OS is Windows XP Home with Service Pack 2. Thanks. :/
