I am going to be switching my wired Internt connection to a WiFi setup, now that I have the Laptop. What is the best way to do this? In the setup manual for the wireless card, it mentions Infrastructure and Ad-Hoc, Which is better to use?

It also asks about security type. (64-bit WEP, 128-bit WEP, or WPA-PSK) Which of these is the better choice?

Sorry if these are stupid questions, but I have never worked with a wireless setup before, and I've heard horror stories about people having their wireless network set up wrong, and giving ANYONE with a wireless connection (Six ) complete access to their computer unknowingly...
