how to configure my laptop for WPA2 setup

I can not hook my T42 on this wireless connection (my neighbors), but it worked on my wife’s computer.

It said the following:
Unable to connec to the selected wireless network.
You may need to configure your system to support the authentication method that in use.

Wireless mode is 802 11g

install that update from Microsoft first and see if it works and then if you are still unable to connect update your driver (link in my first post)
let me know if that solves your problem
Make sure your lap top can connect to a "g" wireless network, then work on getting driver that allows you to connect to the "g" network using your wireless card if you can find it you have to replace it for a newer one that supports this type wireless network  connection ans safety protocols. I hope this helps you to answer your question
